Mechanism of Action
Oxybenzone
Although benzophenones are primarily UV-B absorbers, oxybenzone absorbs well through UV-A II. Oxybenzone can be considered a broad-spectrum absorber. It significantly augments UV-B protection when used in a given formula.
Avobenzone
Often referred to by its trade name, Parsol 1789, butyl methoxydibenzoylmethane or avobenzone provides superior protection through a large portion of the UV-A range, including UV-A I. A significant addition to sunscreen products for true broad-spectrum UV protection, concerns have been raised regarding its photostability and its potential to degrade other sunscreen ingredients in products in which it is used.
Titanium dioxide
The ideal sunscreen agent would be chemically inert, safe, and absorb or reflect through the full UV spectrum. Titanium dioxide meets these criteria limited only by aesthetics. By decreasing the particle size of this pigment to microsize or ultrafine grades, thereby making it less visible on the skin surface, some of these advantages could be used. This ingredient can be classified as a broad-spectrum agent.
Padimate O
Padimate O is the most potent UV-B absorber.
