Moisturizing Booster is a hydrating serum with plumping and revitalizing effects. Rich in small-molecule and macromolecular hyaluronic acid, this gel quickly and profoundly hydrates all layers of skin. Reinforced with an NMF-like complex containing almost all of the natural moisturizing factors, including PCA and many amino acids, Moisturizing Booster replenishes the moisture-binding capacity of the epidermis and protects the skin from dehydration.
