Analysis of UV Filters in Sunscreen Products on the Lithuanian Pharmacy Market

Abstract

Ultraviolet (UV) radiation is a recognized human carcinogen, and topical sunscreens remain the primary strategy for photoprotection. As community pharmacies represent trusted sources of skincare products, evaluating the composition of sunscreens distributed through this channel is particularly relevant. This cross-sectional market analysis investigated UV filters used in sunscreen products available in Lithuanian community pharmacies in November–December 2025. Products were identified through online pharmacy catalogs and assessed for labeled Sun Protection Factor (SPF), number and type of UV filters, and filter combinations in accordance with Regulation (EC) No 1223/2009. A total of 467 products from 98 brands were included, and 26 distinct UV filters were identified. Triazine derivatives predominated, particularly bis-ethylhexyloxyphenol methoxyphenyl triazine (64.67%) and ethylhexyl triazone (58.03%). Most products (61.67%) were labeled SPF ≥ 50 and contained multiple UV filters (mean 4.29 ± 1.66), with significantly more filters in SPF ≥ 50 formulations (p < 0.001). These results indicate that sunscreen products available in Lithuanian pharmacies are dominated by high-SPF formulations and selective multi-filter systems, providing region-specific insights relevant to regulatory oversight and consumer exposure assessment.
