Fragrances and dyes are commonly added to cosmetics to improve their scent and appearance. However, these ingredients are also among the most common causes of allergic contact dermatitis.
Dermatologist and cosmetologist Paulina Gruselionytė, who specializes in inflammatory skin conditions such as dermatitis, rosacea, and acne, explains how these additives may affect skin health.
"In my experience, fragrances and dyes in cosmetics can significantly affect both skin health and overall well-being. Some of my patients notice a remarkable improvement after reducing unnecessary fragrances not only in cosmetics but also in their home and work environments."
What Are the Risks of Using Products with Fragrances and Dyes?
For people with sensitive skin, fragrances and colorants may contribute to:
- Skin irritation and rashes.
- Itching and redness.
- Eczema flare-ups.
- Chronic skin inflammation.
- Dryness and flaking.

Ingredients to Watch For
- Fragrance (Parfum). This single ingredient name can represent dozens or even hundreds of fragrance chemicals, some of which may trigger allergic reactions.
- Linalool, Limonene, Citral, Geraniol, Eugenol, and Cinnamal. These common fragrance allergens may cause skin reactions, even when derived from natural sources.
- Synthetic colorants such as CI 17200, CI 19140, and CI 42090. Frequently used in makeup products, especially lipsticks, eyeshadows, and blushes.
-
Red dyes.
- CI 15850 (Red 6 and Red 7), commonly found in lipsticks.
- Carmine (CI 75470), a natural dye derived from insects that may also cause allergic reactions.
- CI 17200 and CI 16035 (Red 33 and Red 40), synthetic dyes associated with skin irritation in susceptible individuals.
- Purple dyes. Often created by combining red and blue pigments, which may carry similar allergy risks.
Why Can Fragrances and Dyes Irritate the Skin?
- Some dyes are derived from azo compounds, which are recognized allergens.
- Makeup products often contain relatively higher concentrations of colorants, increasing skin exposure.
- Products applied to sensitive areas, such as the lips and around the eyes, typically remain on the skin for extended periods, increasing the likelihood of irritation.
Why Reading the INCI List Matters
The INCI (International Nomenclature of Cosmetic Ingredients) list shows not only which ingredients are present but also their relative concentration.
Ingredients are listed in descending order by quantity. This means that if fragrance (Parfum), common fragrance allergens (such as Linalool), or colorants (such as CI numbers) appear near the beginning of the ingredient list, the product contains relatively larger amounts of them.
Even ingredients listed near the end—typically present at concentrations below 1%—may still trigger reactions in people with sensitive skin.
As a general rule, the fewer ingredients labeled "Parfum," "Colorant," or beginning with "CI," the better—particularly if your skin is prone to irritation, eczema, or dermatitis.
Fragrances and Dyes Are Found Beyond Cosmetics
Potential allergens aren't limited to skincare and makeup. They're also commonly found in everyday household and personal care products, including:
- Scented toilet paper and printed tissues.
- Intimate care products containing fragrances or dyes, including cleansers, sanitary pads, and wet wipes.
- Laundry detergents and fabric softeners with added fragrances and colorants.

The Bottom Line
While fragrances and colorful cosmetics may enhance the user experience, they can also increase the risk of skin irritation, especially for people with sensitive or allergy-prone skin.
Reading ingredient labels, choosing fragrance-free and dye-free products whenever possible, and reducing unnecessary exposure to scented household products may help support healthier, more comfortable skin.
Take care of your skin by choosing products that prioritize gentle, skin-friendly ingredients.
