One of the main active ingredients of SEA BUCK SWITZERLAND is hyaluronic acid which is a endogenous substance. Therfore Hyaluronic acid is very effective and can easily be absorbed by our human skin. Hyaluronic acid is a part of our connective tissue and is embedded between the collagen- and elastin fiber. One of its main capacities is to keep the skin hydrated and to plump it up. It can be considered a multi-talent with supporting and firming properties. With increasing age the endogenous hyaluronic acid production decreases and skincare products containing hyaluronic acid are able to compensate this deficit.
