TKN HA MW 2% is a solution of non-crosslinked hyaluronic acid of medium molecular weight, specially designed to obtain long-lasting results. Hyaluronic acid has the capacity to retain water in a percentage equivalent to thousands of times its molecular weight, providing volumen and favouring epidermal hydration. It activates fibroblastic functions and the synthesis of collagen, as well as various skin growth factors slowing down the ageing processes. TKN HA MW 2% has long-term firming and moisturising properties, providing an immediate smooth effect.
