The Ordinary has several different Retinol based serums, ranging in strength and irritation risk levels.
While Retinol has been studied extensively, it is irritating to the skin and newer technologies exist that mimic the visible effects of Retinol without causing skin irritation.
Plus, The Ordinary Hyaluronic Acid + B5 not only supports skin hydration but can also reduce signs of aging like fine lines and wrinkles.
