N-Acetyl-Glucosamin (NAG), a natural fragment of hyaluronic acid (hyaluronan), stimulates the endogenous formation of hyaluronic acid and supports the turgor of the connective tissue. The turgor has a decisive influence on the elasticity and tightening of the skin. Externally applied hyaluronic acid (hyaluronan) forms a permeable, moisture-retaining film with wrinkle-reducing and plumping effect due to the hydrogen bridge linkage with the keratin of the skin. Together with NAG an increase of skin moisture and a visible wrinkle reduction are obtained. Liposomes enable the transport of NAG through the skin barrier, whose membranes consist of physiological phosphatidylcholine. D-Panthenol (provitamin B5) also supports the transport of NAG and simultaneously has regenerative effects – among others through a stimulated epithelialisation. Barrier-affine ceramides and sebum-related lipids additionally generate a sustainable skin care effect.
