Study of poor-quality sunscreen products

Area of Science:

• Cosmetic Science
• Dermatology
• Public Health

Background:

• Counterfeiting and substandardization of healthcare products, including cosmetics like perfumes, is a global concern.
• While counterfeit cosmetics are known, research on substandard cosmetics, particularly sunscreens, is lacking.
• Sunscreens are crucial for photoprotection against harmful ultraviolet (UV) radiation.

Purpose of the Study:

• To evaluate the photoprotective efficacy of substandard sunscreens.
• To investigate the presence and quantity of UV filters in poor-quality sunscreen products.
• To assess the risks associated with using ineffective sunscreens.

Main Methods:

• In vitro determination of Sun Protection Factor (SPF) and UV-A protection factor (FP-UVA).
• High-performance liquid chromatography (HPLC) analysis to quantify UV filter content.
• Testing of seven sunscreen creams acquired through online purchases.

Main Results:

• None of the tested sunscreen creams contained any UV filters.
• The creams exhibited a lack of both SPF and FP-UVA efficacy.
• The analyzed sunscreens were found to be ineffective for sun protection.

Conclusions:

• The counterfeit and substandard sunscreens evaluated pose a significant risk to users' skin health due to their ineffectiveness.
• Consumers are at risk when using sunscreens that lack adequate photoprotective properties.
• Urgent attention is needed to address the prevalence and dangers of substandard sunscreens in the market.
