Serum containing hyaluronic acid, a latest generation biotechnology product (biomolecule) with strong moisturising and firming effect. Hyaluronic acid is a structural component of the connective tissue of the skin. It can retain up to 1000 times its weight in water, which is gradually released, thus enhancing skin moisture. It is the most effective moisturising ingredient in cosmetology. It contributes to the structural integrity of the cutaneous extracellular tissue, forming a strong supporting net for collagen and elastin fibers and reinforcing skin texture. It restores the skin’s moisture balance and vigour.
