Our hydroquinone-free Skin Brightening Serum is safe and fast-acting. A powerful blend of kojic (2%) and azelaic (10%) acids helps exfoliate the skin and generate cellular turnover to visibly reduce discoloration and even out skin tone (Click here to see before-and-after photo). All our formulas include our unique patented COSMEDERM-7 technology, which helps minimize irritation and inflammation in the skin that can cause redness and premature aging.
