Nourish and protect your skin with Mad Hippie Super A Serum. This novel formula features HPR, a form of vitamin A that is readily available to the body without having to undergo metabolic conversion the way retinol does. HPR supports youthful-looking skin. Also includes phytoceramides, sodium hyaluronate (hyaluronic acid), oat beta glucans and aloe vera which work together to aid moisture retention and skin hydration for soft, supple skin.
