Explained: Foundation Colours Standards, Composition, and Industrial Use

Types of Foundation Colours

Selecting the right foundation colour is essential for achieving a natural, flawless finish that enhances your complexion. The ideal match closely aligns with your skin's undertone—whether warm, cool, neutral, olive, or beige—ensuring seamless blending and long-lasting wear. Below is a detailed breakdown of the most common foundation colour types, their characteristics, and who they best suit.

Beige Tones

Beige foundation shades offer a balanced blend of warm and cool undertones, making them ideal for skin tones that fall in the middle of the spectrum. These versatile shades include variations like sand, taupe, and light caramel, allowing for precise customization to match natural skin tones.

Advantages
  • Blends seamlessly with a wide range of skin tones
  • Natural, skin-like finish
  • Allows skin to breathe under makeup
  • Widely available and commonly used in drugstore and luxury brands
Limitations
  • May appear ashy on very cool or very warm undertones
  • Can oxidize and darken slightly after application
  • Less effective at correcting extreme redness or sallowness

Best for: Medium skin tones, neutral complexions, everyday wear

Olive Undertones

Olive skin features subtle green or yellow undertones that don’t fit neatly into warm or cool categories. Foundations for olive skin often contain a hint of yellow, red, or golden pigments to neutralize greenish hues and create a harmonious, even complexion.

Advantages
  • Neutralizes redness and discoloration
  • Enhances natural warmth without looking orange
  • Provides a smooth, natural-looking finish
  • Great for Mediterranean, South Asian, and Middle Eastern skin tones
Limitations
  • Harder to find in standard foundation ranges
  • May appear too yellow if undertone isn't matched correctly
  • Can shift in colour under artificial lighting

Best for: Olive, tan, and golden skin tones; those with greenish or yellowish undertones

Cool Undertones

Cool-toned skin often exhibits pink, red, or bluish undertones, especially in the cheeks and wrists. Foundations in cool shades—such as porcelain, rose beige, and pink-neutral—help balance warmth and create a fresh, even appearance.

Advantages
  • Minimizes redness and flushing
  • Creates a bright, radiant look
  • Complements fair to medium skin tones with pink undertones
  • Offers a clean, polished finish
Limitations
  • Can appear ashy or gray on deeper or warm-toned skin
  • May emphasize dryness or texture if not well-formulated
  • Limited shade range in some brands

Best for: Fair to medium skin with pink or red undertones; ideal for winter and spring palettes

Warm Undertones

Warm skin tones have golden, peachy, or honey undertones and often tan easily. Foundations with warm bases—like golden beige, honey, caramel, and butterscotch—enhance natural radiance and prevent the skin from looking dull or washed out.

Advantages
  • Enhances natural glow and warmth
  • Blends beautifully with sun-kissed skin
  • Reduces the appearance of sallowness
  • Ideal for autumn and summer complexions
Limitations
  • Can look orange or muddy on cool-toned skin

  • Some formulas can oxidize and darken over time

Best for: Golden, tan, and deep skin tones; those with yellow or golden undertones

Neutral Undertones

Neutral skin strikes a perfect balance between warm and cool undertones, making it highly versatile for foundation selection. These complexions can wear a wide range of shades—from pinkish beiges to golden neutrals—without looking too warm or too cool.

Advantages
  • Highly adaptable to various foundation shades
  • Less prone to discoloration or ashy appearance
  • Can experiment with seasonal colour changes
  • Looks natural in both natural and artificial lighting
Limitations
  • May still lean slightly warm or cool depending on lighting
  • Can be challenging to identify exact undertone
  • Some neutral shades may still shift toward pink or yellow over time

Best for: Versatile complexions; ideal for those who tan evenly and don’t flush easily

Foundation Type Best For Skin With Key Characteristics Common Shades Top Tips
Beige Tones Neutral to medium skin Balanced warm-cool mix Sand, taupe, caramel Test in natural light to avoid ashy results
Olive Undertones Greenish-yellow tones Unique blend, not purely warm/cool Olive beige, golden neutral Look for "olive" or "neutral warm" labels
Cool Undertones Pink, red, or blue undertones Fresh, bright appearance Pink beige, porcelain, rose Avoid overly yellow formulas
Warm Undertones Golden, honey, or peachy tones Radiant, sun-kissed glow Golden beige, honey, caramel Use a primer to prevent oxidation
Neutral Undertones Equal warm-cool balance Highly versatile True beige, neutral warm/cool Can experiment with seasonal shades

Expert Tip: Always test foundation on your jawline in natural light to ensure the most accurate match. Swatching on the hand or wrist can be misleading due to differing skin tones. Additionally, consider how your skin changes with seasons—many people benefit from having two shades (lighter for winter, darker for summer).

Ingredients Used in Making Foundation Colours: A Comprehensive Guide

Foundation is one of the most essential products in modern makeup routines, designed to even out skin tone, provide coverage, and enhance facial appearance. The performance, texture, longevity, and safety of a foundation depend heavily on its formulation. Understanding the key ingredients helps consumers make informed choices based on skin type, desired finish, and long-term skincare benefits.

Core Ingredients in Foundation Formulations

Modern foundations combine pigments, binders, emollients, and functional additives to deliver a balanced blend of cosmetic appeal and skin compatibility. Below is a detailed breakdown of the most critical ingredients used across high-quality foundation lines, including premium brands like Dermacol.

Titanium Dioxide

A naturally occurring mineral, titanium dioxide is a powerful white pigment widely used in cosmetics for its excellent opacity and UV-protective properties. It acts as a physical sunscreen by reflecting and scattering harmful UVA and UVB rays, making it ideal for daily wear foundations.

Beyond sun protection, titanium dioxide enhances coverage by providing a bright, even base that helps neutralize discoloration. Its fine particle size allows for smooth blending into the skin without clogging pores, making it especially suitable for sensitive and acne-prone skin types. Additionally, it contributes to the creamy consistency of liquid and compact foundations, improving spreadability and finish.

Iron Oxides

Iron oxides are the cornerstone of foundation color technology, offering a wide spectrum of natural-looking shades through combinations of red, yellow, and black pigments. These inorganic compounds are prized for their exceptional stability, light-fastness (resistance to fading in sunlight), and low reactivity, ensuring consistent color performance throughout the day.

Available in both natural and synthetic forms, iron oxides are non-comedogenic and safe for most skin types, including those with sensitivities or conditions like rosacea. In formulations such as Dermacol foundation, iron oxides enable precise shade matching across diverse skin tones, from fair to deep complexions. Their compatibility with water- and oil-based systems makes them versatile in liquid, cream, powder, and stick foundations.

Mica

Mica is a naturally occurring silicate mineral known for its luminous, reflective properties. When finely milled and added to foundation, it imparts a soft radiance that mimics healthy, well-lit skin. This luminosity helps blur imperfections such as fine lines, enlarged pores, and minor blemishes by diffusing light across the skin’s surface.

Widely used in anti-aging and illuminating foundations, mica enhances the overall finish without appearing glittery or overly shiny. It also improves the slip of the product during application, allowing for seamless blending. Ethically sourced mica is increasingly prioritized by cosmetic brands to ensure responsible mining practices and sustainability.

Ethylene/Glycidyl Methacrylate Copolymer

This synthetic polymer functions as a film-forming agent and thickener in advanced foundation formulas. By creating a flexible, breathable film on the skin, it enhances wear time and prevents smudging, transfer, or breakdown due to sweat and moisture.

The copolymer improves emulsion stability, ensuring that oil and water components remain well-blended during storage and use. It also reduces water evaporation from the formula, helping the foundation maintain its texture and adherence over extended periods. This ingredient is particularly beneficial in long-wear and waterproof foundations, where durability is key.

Dimethicone

A lightweight silicone oil, dimethicone is a star ingredient in many high-performance foundations due to its ability to create a silky-smooth texture and improve application. It fills in fine lines and pores temporarily, creating an airbrushed effect that serves as an ideal canvas for makeup.

Dimethicone forms a protective barrier on the skin that locks in moisture while shielding against environmental pollutants. It also prevents foundation from settling into creases, maintaining a fresh appearance throughout the day. Non-comedogenic and hypoallergenic, it is generally safe for all skin types, including oily and combination skin, where it provides hydration without greasiness.

Ingredient Primary Function Skin Benefits Common In
Titanium Dioxide Pigment, UV protection Shields skin from sun damage, evens tone, suitable for sensitive skin Mineral foundations, SPF-infused bases
Iron Oxides Color pigmentation Natural-looking coverage, color stability, non-reactive All foundation types, especially full-coverage
Mica Light reflection, texture enhancement Blurs imperfections, adds radiance, soft-focus finish Luminous, anti-aging, and pressed foundations
Ethylene/Glycidyl Methacrylate Copolymer Film former, stabilizer Long-lasting wear, water resistance, reduced touch-ups Long-wear and transfer-resistant formulas
Dimethicone Emollient, primer effect Smooths texture, fills pores, locks in moisture Silicone-based and pore-minimizing foundations

Why These Ingredients Matter

  • Customizable Coverage: The combination of titanium dioxide and iron oxides allows manufacturers to create foundations with buildable, full, or sheer coverage while maintaining a natural appearance.
  • Extended Wear: Polymers and silicones work together to anchor the foundation to the skin, resisting fading, flaking, or oxidation over time.
  • Skin-Friendly Formulas: Many of these ingredients are non-irritating and compatible with sensitive skin, reducing the risk of breakouts or allergic reactions.
  • Multifunctional Benefits: Beyond aesthetics, ingredients like titanium dioxide and dimethicone offer skincare advantages such as sun protection and hydration.
  • Versatility Across Shades: Iron oxides enable inclusive shade ranges, supporting diverse skin tones in products like Dermacol foundation, which is renowned for its extensive color matching.
  • Important: While these ingredients are generally safe, individuals with specific sensitivities—especially to silicones or mineral particles—should perform patch tests before full application. Always check product labels for ethically sourced mica and non-nano titanium dioxide if these concerns apply. Choosing the right foundation involves balancing ingredient benefits with your skin type and lifestyle needs.

    How to Choose the Perfect Foundation Colour

    Selecting the right foundation colour and formula is essential for achieving a flawless, natural-looking complexion. The ideal foundation not only matches your skin tone precisely but also complements your skin type, lifestyle, and environmental conditions. Understanding the key factors involved ensures a seamless blend, long-lasting wear, and healthy-looking skin.

    Skin Type Compatibility

    Your skin type plays a crucial role in determining which foundation formula will perform best. The wrong choice can lead to dryness, excess shine, clogged pores, or irritation—especially when wearing foundation daily.

    • Dry Skin: Opt for oil-based, hydrating, or cream foundations that lock in moisture and prevent flaking. Look for ingredients like hyaluronic acid, glycerin, or squalane.
    • Oily Skin: Choose water-based, oil-free, or matte formulations that control sebum production and minimize shine throughout the day.
    • Combination Skin: Use dual-finish products or apply different formulas to different zones (e.g., matte on T-zone, dewy on cheeks).
    • Sensitive Skin: Select fragrance-free, hypoallergenic, and dermatologist-tested foundations to reduce the risk of redness or breakouts.

    Pro tip: Always patch-test new products behind the ear or on the jawline before full application.

    Coverage Preferences

    Foundation coverage ranges from sheer to full, each serving a different aesthetic and functional purpose. Your desired look and skin concerns should guide your selection.

    • Sheer to Light: Ideal for everyday wear, providing a natural finish while evening out minor imperfections. Perfect for those embracing a "no-makeup" makeup look.
    • Medium Coverage: Balances natural appearance with improved skin correction—great for work, events, or casual outings.
    • Full Coverage: Offers maximum opacity to conceal acne scars, hyperpigmentation, redness, and discoloration. Often used for photography, stage, or special occasions.
    • Buildable Formulas: Allow layering without caking, giving flexibility to adjust coverage as needed.

    Key insight: Higher coverage doesn't always mean heavier feel—modern lightweight full-coverage foundations offer both opacity and breathability.

    Desired Finish

    The finish of your foundation dramatically affects your overall complexion look—whether you want a glowing, natural, or polished appearance.

    • Matte Finish: Absorbs oil and reduces shine, making it ideal for oily or combination skin. Common in long-wear and HD formulas.
    • Dewy Finish: Imparts a radiant, hydrated glow by reflecting light—perfect for dry or mature skin to avoid a flat or ashy look.
    • Satin Finish: A balanced middle ground that offers a soft luminosity without excessive shine, suitable for most skin types.
    • Natural/Skin-Like Finish: Mimics real skin texture, often found in tinted moisturizers and serums for a breathable feel.

    Expert note: Pair your foundation finish with appropriate primers and setting powders to enhance longevity and effect.

    Undertone Accuracy

    Matching your foundation’s undertone is just as important as matching the surface shade. An incorrect undertone can result in an unnatural, orange, gray, or ashen appearance—even if the shade seems close.

    • Warm Undertones: Characterized by yellow, golden, or olive hues. Common in medium to deep skin tones. Look for labels like "W" or "golden beige."
    • Cool Undertones: Have pink, red, or blue bases. Often seen in fair to medium skin. Check for "C" or "rose beige" designations.
    • Neutral Undertones: A mix of warm and cool, blending characteristics of both. May suit "N" or "neutral beige" shades.
    • Neutral-Warm/Cool: Slight dominance in one direction—test multiple swatches in natural light for best results.

    Quick test: Check the color of your veins under natural light—greenish suggests warm, bluish indicates cool, and a mix points to neutral.

    Environmental & Climate Considerations

    External conditions such as humidity, temperature, and pollution can significantly impact how your foundation performs throughout the day.

    • Humid Climates: Choose long-wear, sweat-resistant, or transfer-proof formulas to prevent melting and sliding.
    • Dry or Cold Environments: Prioritize moisturizing foundations with nourishing ingredients to prevent cracking or flaking.
    • Hot & Sunny Conditions: Consider foundations with SPF or pair with sunscreen, and use setting sprays for added protection and hold.
    • Urban Areas: Pollution-blocking foundations with antioxidant-rich formulas help protect skin and maintain makeup integrity.

    Smart strategy: Adapt your foundation seasonally—lighter, matte finishes in summer; richer, dewy options in winter.

    Shade Matching Techniques

    Getting the exact foundation colour match requires more than just comparing bottles in-store. Lighting, skin condition, and application method all influence the final look.

    • Test foundation on your jawline or neck—not the hand or wrist—to ensure seamless blending with your face and body.
    • Evaluate the match in natural daylight, not under artificial store lighting.
    • Wait a few minutes after application to see how the foundation oxidizes (darkens slightly) before deciding.
    • Use shade-matching apps or in-store spectrophotometers (like those from L'Oréal or Sephora) for precise digital analysis.
    • Consider seasonal changes—your shade may need adjustment between summer and winter.

    Golden rule: The right foundation should disappear into your skin, not sit on top of it.

    Professional Recommendation: When in doubt, opt for a reputable brand with a wide shade range and inclusive undertone options. Brands like Fenty Beauty, L'Oréal True Match, or NARS offer scientifically developed formulas with diverse color matching. Always sample before committing—many brands offer travel sizes or testers. For best results, consult a makeup artist or dermatologist, especially if you have complex skin concerns like melasma or rosacea.

    • Inclusivity: Support brands that offer 40+ shades and diverse undertones for accurate matches across all skin tones.

    Mastering Foundation Application: A Complete Guide to Flawless Coverage

    Applying foundation correctly is the cornerstone of any polished makeup look. Whether you're aiming for natural daytime coverage or full-coverage glam, the right technique can transform your complexion. This comprehensive guide walks you through each essential step—from skin prep to setting—for a seamless, long-lasting finish that enhances your natural beauty. Learn how to avoid common mistakes and achieve a professional-quality result every time.

    Pro Tip: Always apply foundation in natural daylight when possible. Artificial lighting can distort skin tone, leading to mismatched shades or uneven blending.

    Step-by-Step Foundation Application Process

    1. Prep the Skin for Optimal Adhesion

      Proper skincare is the foundation of flawless foundation. Begin with a gentle cleanser to remove impurities, followed by a toner to balance your skin’s pH. Apply a lightweight moisturizer suited to your skin type—oily, dry, or combination—to hydrate and plump the skin. Allow 5–10 minutes for absorption before proceeding.

      For enhanced staying power and a smooth canvas, use a makeup primer. Primers fill in fine lines, minimize pores, and create a barrier between your skin and makeup, preventing oxidation and extending wear. Look for silicone-based primers for longevity or hydrating versions for dry skin. This prep routine is essential for achieving a waterproof foundation effect, especially in humid conditions or during long wear.

    2. Choose the Right Application Technique

      The tool you use dramatically impacts your foundation’s finish. Here are the most effective options:

      • Damp Beauty Blender: Ideal for a natural, airbrushed look. Dampen the sponge, then bounce the foundation onto the skin for seamless blending.
      • Foam or Flat Foundation Brush: Provides medium to full coverage with precision. Use stippling motions to build product evenly.
      • Synthetic Kabuki Brush: Great for buffing in liquid or cream foundations for a polished, Instagram-ready finish.

      Always start application from the center of the face—cheeks, nose, and forehead—then blend outward toward the hairline and jawline. This technique ensures you don’t waste product and allows for a more natural gradient.

    3. Use the Right Amount of Product

      Less is more when it comes to foundation. Applying too much at once leads to a heavy, cakey appearance and can settle into fine lines. A general rule: start with a pea-sized amount for light to medium coverage. For full coverage, use two pea-sized drops—one for each side of the face.

      Apply in thin layers, building up only where needed (such as redness around the nose or under the eyes). This method allows for better control, reduces product waste, and prevents clogged pores. Remember, you can always add more, but removing excess foundation without disturbing your base is challenging.

    4. Master the Art of Blending

      Blending is what separates a professional finish from a patchy one. Pay special attention to transition zones:

      • Jawline and Neck: Extend foundation slightly onto the neck to avoid a harsh line of demarcation.
      • Hairline and Temples: Use a light hand to prevent product buildup in fine hairs.
      • T-Zone: Blend carefully around the nose, forehead, and chin—common areas for shine and caking.
      • Eyelids and Under-Eye Area: Gently press foundation into these delicate zones using a sponge or fingertip to avoid creasing.

      Ensure no visible edges or color shifts exist between your face and neck. A well-blended foundation should look like your skin—just better.

    5. Set the Foundation for Longevity

      Setting locks in your foundation and prevents creasing, fading, or transferring. Choose your setting method based on skin type and desired finish:

      • Setting Powder: Use a translucent or color-matched powder with a fluffy brush for oily or combination skin. Focus on the T-zone to control shine.
      • Setting Spray: Ideal for dry or mature skin. Spritz a hydrating, long-wear spray to melt powders together and add a dewy glow.
      • Baking (Optional): For extra staying power, apply a thick layer of loose powder under the eyes and on oily areas, let it sit for 2–5 minutes, then dust off. Best for photography or long events.

      Always apply setting products evenly and in moderation. Over-powdering can make the skin look dry or ashy, especially in photos. The goal is to enhance—not mask—your flawless base.

    Application Step Best For Avoid If Recommended Tools
    Skin Prep All skin types Rushing or skipping moisturizer Cleanser, toner, moisturizer, primer
    Foundation Application Liquid, cream, or hybrid formulas Using dry sponge or dirty brushes Damp beauty blender, flat brush, kabuki
    Blending Seamless coverage Skipping jawline/neck Sponge, clean brush, fingertips
    Setting Long wear, photography, humid climates Dry skin with heavy powder Translucent powder, setting spray, puff
    Touch-Ups Oily skin, long days Over-applying during the day Blotting papers, pressed powder, mist

    Expert Tip: Test your foundation shade on your jawline in natural light. The right match should disappear into your skin without leaving a visible line. Keep your skin type and seasonal changes in mind—your winter shade may differ from your summer one.

    Additional Tips for a Flawless Finish

    • Wash your application tools weekly to prevent bacteria buildup and patchy application.
    • Store foundation in a cool, dry place away from direct sunlight to preserve formula integrity.
    • Exfoliate 1–2 times per week to prevent flakiness, especially if you wear makeup daily.
    • Use color correctors under foundation to neutralize redness, dark circles, or sallowness.
    • Reapply setting spray midday for a refreshed look without adding more product.

    Perfect foundation application is both an art and a science. With the right prep, tools, and technique, you can achieve a radiant, even complexion that lasts all day. Remember, consistency and practice are key. Over time, you'll develop a personalized routine that works best for your skin type and lifestyle. When in doubt, less product and more blending will always lead to a more natural, flattering result.

    Frequently Asked Questions About Foundation Makeup

    Q1: Can foundation colors be mixed to achieve a better skin match?

    Yes, mixing foundation shades is a widely used technique among both professional makeup artists and beauty enthusiasts to create a custom color that perfectly matches your skin tone. Most complexions have unique undertones (cool, warm, neutral, or olive) and varying levels of depth that may not be fully captured by a single off-the-shelf shade. By blending two or more foundations—such as a lighter and darker tone, or one with a warmer undertone and another with a cooler one—you can fine-tune the result for a seamless, natural finish.

    • How to Mix Foundations: Start by placing small amounts of each shade on the back of your hand or a palette. Blend them together with a brush, sponge, or clean fingertip before applying to your face.
    • Test Before Wearing: Always apply the mixed foundation to your jawline or neck and observe it in natural light. Wait 5–10 minutes to see how it oxidizes and settles into your skin.
    • Pro Tip: Consider mixing a full-coverage foundation with a lighter one to adjust opacity without changing the color.
    • Caution: Avoid mixing foundations with vastly different formulas (e.g., water-based with oil-based), as this can cause pilling, separation, or uneven texture.

    This method is especially helpful for seasonal changes when your skin tone may darken in summer or lighten in winter.

    Q2: What is the best method for removing foundation stains from clothes?

    Foundation stains, especially those containing oils and pigments, can be stubborn but are often removable if treated quickly and correctly. Since makeup products are designed to adhere to skin, they can bond with fabric fibers if not addressed promptly.

    • Act Immediately: As soon as the stain occurs, gently blot (do not rub) the area with a clean paper towel or cloth to lift excess product. Rubbing can push the foundation deeper into the fibers and spread the stain.
    • Rinse with Cold Water: Hold the stained area under cold running water from the back side to push the stain out, not further in.
    • Apply a Stain Remover: Use a liquid laundry detergent, dish soap (like Dawn), or a dedicated makeup stain remover. Apply directly to the stain and gently work it in with your fingers or a soft brush.
    • Soak if Necessary: For older or set-in stains, soak the garment in cold water with detergent for 30 minutes to an hour before washing.
    • Wash According to Care Label: Launder the clothing using the warmest water safe for the fabric. Check the stain after washing—do not dry in the dryer until the stain is completely gone, as heat can set it permanently.

    For delicate fabrics or persistent stains, consider taking the garment to a professional cleaner and point out the makeup origin of the stain.

    Q3: Do foundations contain sunscreen, and is it enough for sun protection?

    Yes, many foundations today include SPF (Sun Protection Factor) as part of their formulation, typically ranging from SPF 15 to SPF 30. These products offer some defense against UVB rays, which cause sunburn, and sometimes UVA rays, which contribute to aging and skin damage.

    • Benefits of SPF in Foundation: Provides daily, lightweight protection ideal for incidental sun exposure, such as commuting or running errands.
    • Limitations: Most people don’t apply enough foundation to achieve the labeled SPF protection. Dermatologists recommend using about 1/4 teaspoon for the face, but typical application is much less.
    • Reapplication Challenge: Unlike sunscreen, foundation isn’t designed to be reapplied every two hours, especially over makeup.
    • Not a Replacement: Foundation with SPF should not replace a dedicated broad-spectrum sunscreen. For extended outdoor activities, always apply a proper sunscreen underneath your makeup.

    For optimal protection, layer a moisturizer or primer with SPF under your foundation, or use a setting spray with SPF for touch-ups during the day.

    Q4: How should foundation be stored to maximize its shelf life and safety?

    Proper storage is key to maintaining the integrity, texture, and hygiene of your foundation. Most liquid and cream foundations last 6–12 months after opening, while powders can last up to 2 years. However, poor storage can shorten this lifespan and promote bacterial growth.

    • Avoid Heat and Sunlight: Keep foundation away from windows, bathrooms (due to humidity), and hot environments like cars. Heat can break down active ingredients and alter consistency.
    • Keep It Sealed: Always close the cap tightly to minimize air exposure, which can cause oxidation and drying.
    • Use Clean Application Tools: Apply with sanitized brushes, sponges, or fingertips to prevent introducing bacteria. Never share makeup applicators.
    • Refrigeration (Optional): Some natural or preservative-free foundations benefit from cool storage. Check the manufacturer’s instructions—refrigeration can extend shelf life and soothe skin when applied cold.
    • Watch for Signs of Spoilage: Change in smell, texture (separation, thickening), or color, as well as irritation upon application, are signs it’s time to replace the product.

    Writing the purchase or opening date on the bottle with a waterproof marker helps track freshness and ensures you’re using safe, effective makeup.
