Octyl Methoxycinnamate (Octinoxate) is an oil-soluble organic UVB filter widely used in sun-care formulations. It works by absorbing UVB radiation and converting it into low-energy heat, helping protect skin from sunburn and UV-induced damage while contributing to a smooth, lightweight sensory feel.

Helping prevent sunburn, photoaging, and DNA damage
