This super hydrating oil-free serum is a tall drink of water for the skin.  Clinical studies showed that this combination of polyphenol-rich grape water and hydrating hyaluronic acid reduced skin redness rapidly (as compared to skin not treated with serum) following exposure to lactic acid, so this product is optimal for skin that is sensitized from active anti-aging or anti-acne treatments.  This pairs perfectly with Caudalie Vinosource Moisturizing Sorbet, and is ideal for acne-prone skin as polyphenols are clinically proven to improve inflammatory acne.
