Soskin hyaluronic serum contains two hyaluronic acids with two complementary actions. A hyaluronic acid of intermediate molecular weight acts on the surface with a film-forming effect to reconstruct the missing or deteriorated protective lipid film. Hyaluronic acid fragments of a lower molecular weight penetrate deeper into the skin's layers to lastingly binds moisture in the skin to restore an optimal rate of nmf (natural moisturizing factors). Ideal to be used when skin needs deep recovery, when skin is subject to local skin reactions (dehydration, sun, air conditioning) or as a result of cosmetic procedures.
