Octocrylene
Octocrylene is a widely used synthetic UV filter found in sunscreens, moisturisers and lip balms. It helps protect skin from UVB and short-wave UVA rays while also stabilising other sunscreen ingredients so they last longer in sunlight. It is a clear, oil-soluble liquid that feels light on the skin.
How it works in skincare
In cosmetic formulations octocrylene works as a photostable UVB absorber and weak UVA filter that converts harmful ultraviolet radiation into harmless heat. It is frequently paired with avobenzone and other filters because it prevents them from breaking down when exposed to sunlight, helping the overall SPF remain effective for longer. Its oil-soluble nature allows it to blend seamlessly into creams, lotions and lip products, giving a smooth, non-greasy finish.
