What it is & what it does
Octocrylene is a UVB/UVA2 filter that also helps photostabilize avobenzone.
WHAT IT IS: Octocrylene is an organic sunscreen filter used primarily for UVB and shorter UVA-region support, with additional photostabilizing roles in some formulations.
HOW IT WORKS / EVIDENCE: It can help stabilize other filters such as avobenzone in suitable systems. This is a formulation function, not independent proof of broad-spectrum protection. Some people can develop contact or photoallergic reactions to octocrylene, and sunscreen tolerability varies.
WHY THE FINISHED PRODUCT MATTERS: The whole sunscreen's tested protection and suitability matter more than the ingredient's reputation alone. No ingredient name alone establishes the measured clinical result of a complete formula.
