Octinoxate is a chemical compound found in sunscreen formulations, formed from a combination of methoxycinnamic acid and 2-ethylhexanol. This compound functions as UV filter by absorbing the sun’s rays before they can reach the deeper layers of the skin, where they often cause damage and signs of aging.
Octinoxate primarily absorbs UVB rays, the type of rays most commonly associated with sunburn and skin cancer. Because it primarily absorbs one type of UV rays, octinoxate is not considered a broad spectrum sunscreen ingredient. Therefore, it’s best used in conjunction with other UV filters and photostabilizers. In fact, if this compound isn’t combined with other UV filters, it can cause sun sensitivity.
In addition to preventing sun damage and absorbing UVB rays, octinoxate has also been found to be helpful in reduction and prevention of scarring.
