Allergy & Safety Information
4-Methylbenzylidene Camphor is generally safe for most people but may cause irritation or allergic reactions in sensitive individuals. If you experience redness, itching, or swelling after using a product with this ingredient, discontinue use and consult a dermatologist.

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 4-Methylbenzylidene Camphor: 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.
