It works by restoring moisture in the skin's numerous layers. The Ordinary's Hyaluronic Acid 2% + B5 penetrates the skin to reach its deeper layers, providing long-lasting hydration and visible freshening and moisture retention for skin that appears softer, smoother, and healthier. In addition, vitamin B5, an essential ingredient of this serum, boosts the skin's barrier function and stimulates the development of stronger tissue to mend dry and damaged regions. Apply a small amount on your face before applying oils, moisturizers, and creams in the mornings and evenings.
