GUNILLA Botanical Cell Rejuvenator Active Serum is a light, transparent, and highly effective concentrate that maximizes the anti-aging potential of your skin's natural repair cycle. Because it is comprised of smaller molecules, this serum enables the active ingredients within to penetrate the skin's lipid barrier to nourish the deepest layers and help prevent the breakdown of elastin and collagen. This deep penetration infuses the antioxidants, vitamins, and botanical nutrients of the serum to calm and soothe skin while rejuvenating, revelaing new cells, and reducing the appearance of fine lines and wrinkles..
