What it is
Oxybenzone is a long-established organic (chemical) UV filter that works by absorbing ultraviolet energy and dissipating it as heat. It covers UVB and the shorter UVA2 wavelengths and is often combined with other filters for broader coverage. It is photostable and has historically been used both for skin protection and to help stabilize other ingredients against light.

Safety & warnings
Oxybenzone is a recognized skin-penetrating filter and has been associated with contact and photo-contact sensitivity in some individuals, so people prone to sunscreen reactions sometimes prefer alternatives. It has been the subject of endocrine and environmental scrutiny, including concerns about reef ecosystems, which has led some jurisdictions to restrict it. It is non-comedogenic and remains permitted within regulated maximum levels.
Origin & sourcing
Synthetic. It is a benzophenone-class organic compound manufactured for use as a UV-absorbing active.
History
Oxybenzone is one of the older organic UV filters and has been used in sunscreens for decades, which is why it appears widely in legacy formulations. In recent years some regions and retailers have moved away from it amid environmental and regulatory discussion, while it remains an approved active within set concentration limits in several markets.
