Does avobenzone absorb through the skin?

Avobenzone, like other organic UV filters, can penetrate into deeper skin layers to absorb UVA radiation. However, safety assessments have found it acceptable at concentrations used in sunscreens, and most regulatory bodies approve it for topical use.

Does avobenzone break down in sunlight?

Yes, avobenzone is known to degrade when exposed to sunlight unless paired with photostabilizer ingredients that extend its UV-absorbing effectiveness. This is why formulas using avobenzone typically include stabilizing actives.
