Ingredient
Avobenzone
What is Avobenzone?
Avobenzone is a synthetic chemical used in sunscreen products to absorb the full spectrum of UVA rays from the sun, helping to protect the skin from damage. It is typically produced through chemical synthesis processes.
Avobenzone is favored in sunscreens for its ability to protect against a wide range of UVA rays, which are known to contribute to skin aging and cancer. However, it can be unstable in sunlight and break down, potentially reducing its effectiveness unless stabilized by other ingredients. The evidence on its health impact when used properly in sunscreen is generally considered acceptable, though some sources mention it can cause skin sensitivity in rare cases.
When reading labels, note that avobenzone is often part of broader formulations containing other UV filters that help stabilize it and enhance sun protection.
