Homosalate

What it does

Homosalate is an organic UVB sunscreen filter that absorbs UV radiation in the 280-320nm range, converting it to heat to protect skin from sunburn and photoaging. It is commonly used in combination with other filters in broad-spectrum formulas. At typical use concentrations (up to 13% in US formulations), it provides moderate UVB protection.
