Homosalate
Homosalate is a clear, oily liquid commonly used in UK sunscreens and daily moisturisers with SPF. It works as a chemical (organic) UV filter that helps protect skin from UVB rays, which can cause burning and contribute to premature ageing. Shoppers will often find it paired with other filters for broad-spectrum protection in lightweight, non-greasy formulas.
How it works in skincare
In cosmetics and skincare Homosalate functions as an oil-soluble UVB absorber. It is incorporated into emulsions, lotions and sprays where it converts harmful ultraviolet radiation into harmless heat, thereby helping to stabilise the overall SPF system and prevent the degradation of other UV filters within the product.

Where it comes from
Although used in its synthetic form in cosmetics, homosalate is chemically related to compounds naturally occurring in the bark, leaves and flowers of certain plants in the Salicaceae family.
