Allergy & Safety Information

About UV Filter / Sunscreen Agent Ingredients
UV filters absorb or reflect ultraviolet radiation to protect skin from UV-induced damage. They fall into two categories: chemical filters (which absorb UV and convert it to heat) and mineral filters (zinc oxide, titanium dioxide, which physically scatter UV). Both can cause reactions in sensitised individuals, though mineral filters have lower overall allergenicity.
Relevance for Octocrylene: The most allergenic chemical UV filters include oxybenzone (benzophenone-3), octocrylene, and avobenzone. If you react to chemical sunscreens, switching to pure mineral sunscreens (zinc oxide or titanium dioxide only) is usually the safest alternative.
