Skin Balancing Super Antioxidant Concentrate Serum with Retinol is a brilliant serum for all degrees of oily skin. Substantial, well-researched antioxidants, cell-communicating ingredients and potent anti-irritants are delivered in a silky base that feels weightless on skin. Once applied, this product forms a breathable barrier which not only protects the skin but works to nourish and repair it. It also significantly reduces irritation and inflammation from environmental exposure, allowing skin to repair itself naturally. Those with oily skin will love the special absorbent ingredients that leave a smooth matte finish, plus ingredients that normalize how skin behaves. No need for a separate foundation primer, as this provides all the benefits of a primer plus anti-aging and mattifying ingredients! This product is 100% fragrance- and colorant-free.
