Reverse the harsh effects of aging with this gentle, reparative serum. We combined two of the strongest age-fighting ingredients – hyaluronic acid and collagen – to plump and fill wrinkles, leaving skin fresh, soft and supple. Hyaluronic acid is a key component of skin moisture, and as production wanes with age, unwanted wrinkles form. This highly concentrated mixture moisturizes and repairs skin while giving it a soft, velvety feel.
