Octocrylene is a chemical compound commonly used in sunscreens and cosmetic products as a UV filter. It helps protect the skin from harmful ultraviolet rays, which can cause sunburn and skin damage. Octocrylene is often combined with other sunscreen agents to enhance their effectiveness and stability. In addition to its use in sun protection, octocrylene also acts as a solvent and stabilizer for other ingredients in formulations. It is generally considered safe for topical use, but some individuals may experience skin sensitivity or allergic reactions. Always check product labels for specific ingredient information.
