Allergenicity and Unregulated Marketing Claims in Tinted Sunscreens.

Background

Tinted sunscreens are gaining popularity among skin of color populations due to their protection against visible light-induced hyperpigmentation and elimination of the white cast. Despite growing use, little is known about their allergenicity or the reliability of safety-oriented marketing claims.

Objective

To assess the relationship between allergen content, active ingredients, marketing claims, and price in top-rated, best-selling tinted sunscreens.

Methods

We conducted an analysis of 49 tinted sunscreens from 3 major online retailers. Products were evaluated for allergens listed in the 2020 American Contact Dermatitis Society Core Allergen Series, presence of marketing claims, UV filters, and price per ounce.

Results

Ninety-eight percent of products contained at least 1 allergen (mean 3.1). The average price per ounce was $18.95. Products with multiple shade options were more expensive ($22.92 vs $16.65/oz; P = 0.04), while "nano-particle free" products were less expensive ($14.26 vs $20.83/oz; P = 0.04). Marketing claims were abundant (mean 11.7). "Fragrance free," "cruelty free," "reef friendly," and "nano-particle free" claims were associated with fewer allergens (P < 0.05). Octisalate and octinoxate correlated with more allergens; zinc oxide with fewer (P < 0.05).

Conclusions

Tinted sunscreens frequently contain allergens despite safety-related marketing claims. Clinicians should guide product selection based on allergenic potential, active ingredients, and cost.
