SkinMedica Vitamin C and E Complex 1 fl oz.
This highly active serum contains 15% vitamin C in both aqueous and lipid forms. The actives are encased and delivered in a very sophisticated non-aqueous silicone gel delivery system, which acts as an invisible time-release transdermal patch, to transport the actives to the stratum corneum gradually, on demand. The actives are ascorbic acid and tetrahexyldecyl ascorbate.
