Neutralize skin-damaging particles with The Ordinary EUK 134 Serum 0.1%. This lightweight serum contains a rare self-regenerating molecule called EUK which scavenges for free radicals and helps to eliminate them from your skin before they can do any damage. The antioxidant formulation helps to enhance the complexion by protecting skin from harmful pollutants such as smoke, air pollution, and UV-light before they oxidize. The Ordinary’s unique formula boasts an exceptionally high concentration of EUK, which at 0.1% does not sound like a lot, but is actually one of the highest available concentrations on the market. EUK can help to reduce visible redness and protect against the appearance of UV damage. It can be used as a shield against environmental pollutants such as free radicals, hydrogen peroxide and reactive oxygen species, which all contribute to skin imperfections and signs of aging. This formula does not contain any water, silicones, oils, alcohol, nuts, gluten or soy. It is also vegan and cruelty-free. This product should not be used alongside other acids such as glycolic or salicylic acid.
