Area of Science:

• Dermatology
• Cosmetic Science
• Allergology

Background:

• Contact dermatitis from cosmetics is a frequent dermatologic issue, affecting patient quality of life and healthcare costs.
• Approximately 60% of cosmetic-related dermatitis cases are allergic, with skin hygiene, moisturizing, hair, and nail products being common culprits.
• Fragrances, preservatives, and hair dyes are leading causes of cosmetic allergies, but all ingredients, including natural ones, can be sensitizers.

• To aid in the diagnosis, treatment, and prevention of cosmetic contact dermatitis.
• To highlight the diverse range of cosmetic components that can act as potential sensitizers.

Main Methods:

• Literature review of common cosmetic allergens.
• Analysis of dermatological complaint data related to cosmetic products.
• Categorization of frequent allergens by product type and chemical class.

Main Results:

• Fragrances are the primary cause of cosmetic allergies, followed by preservatives and hair dyes.
• Skin hygiene and moisturizing products are the most common sources of contact dermatitis.
• A comprehensive list of potential allergens including fragrances, preservatives, antioxidants, excipients, surfactants, humectants, emulsifiers, natural ingredients, hair dyes, sunscreens, and nail cosmetics is detailed.

Conclusions:

• Understanding frequent cosmetic allergens is essential for managing contact dermatitis.
• All components of cosmetic products, regardless of origin, should be considered potential allergens.
