Traditionally found in mouthwashes and throat lozenges thanks to its antiseptic and anesthetic properties, hexylresorcinol has also been used to treat minor cuts, scrapes and skin infections. However, its ability to target pathways in the skin that lead to hyperpigmentation has propelled it into the skin lightening ingredient category.
In recent studies, 0.5% hexylresorcinol has proven to be just as effective as a 2% concentration of Hydroquinone in correcting the appearance of hyperpigmentation and brightening the skin. Hexylresorcinol has more potential benefits as well, including an ability to reduce the appearance of fine lines and wrinkles, increase protection against UVB and UVA rays, and improve the skin's barrier against pollution and sun exposure. Hexylresorcinol is considered safe for topical use and there are no warnings about its application.
