Background

Homosalate is an organic compound that belongs to salicylates. It is an ester formed from salicylic acid and 3,3,5-trimethylcyclohexanol, a derivative of cyclohexanol. Salicylates prevent direct skin exposure to the sun’s harmful rays by absorbing ultraviolet (UV) light. Homosalate specifically absorbs short-wave UVB rays, which are associated with DNA damage and increased risk of skin cancer.

It is a common ingredient in many commercially available sunscreens. There are no reported adverse effects from homosalate.
