TOSKANI TKN HA XS 2% is a biorevitalising complex of non-crosslinked hyaluronic acid with very low molecular weight, especially designed to optimise skin hydration. Hyaluronic acid has the capacity to retain water in a percentage equivalent to thousands of times its molecular weight, providing volume and favouring epidermal hydration. Thanks to its small molecule, TKN HA XS 2% penetrates deeply into the skin, filling the interfibral spaces of collagen causing water retention. It improves the smoothness of the skin, keeping it firm and elastic with a healthy and youthful appearance.
