This Sesderma cream incorporates a revolutionary ingredient, DMAE (dimethylamino ethanol or deanol), a natural nutrient obtained from fish encapsulated in liposomes that makes your skin instantly firmer, more elastic and smoother by 2 mechanisms: It increases the release of acetylcholine, a neurotransmitter that decreases as we age, producing an increase in muscle tone and stimulates collagen synthesis, reducing wrinkles and increasing skin elasticity.
