homosalate

Homosalate is an FDA-approved sunscreen active ingredient that provides primarily UVB protection. Its UVA range is very narrow, and so it is not used alone in sunscreens. Homosalate is internationally approved for use in sunscreens, up to a maximum concentration of 15%. It’s considered non-sensitizing, and is most often seen in sunscreens rated SPF 30 and greater.

This sunscreen active is one of several currently undergoing further safety testing under the purview of the United States Food and Drug Administration (FDA). This testing is to gain a better understanding of the systemic absorption, metabolism, and elimination of these sunscreen actives when small amounts enter the body via topical use. It’s important to know that the presence of this or other sunscreen actives in the body does not mean your health is at risk. It is anticipated that the additional testing being done will reaffirm the safety of these ingredients; however, those who remain concerned can choose sunscreens with mineral actives (titanium dioxide and zinc oxide) which are not included in the FDA’s new call for additional testing.
