Cell-Communicating Ingredient

Adenosine

Adenosine is a naturally occurring purine nucleoside found in all living cells, where it plays a vital role in energy transfer (as part of ATP) and cell signalling. Applied topically, it acts as a cell-communicating ingredient that can interact with adenosine receptors in the skin to stimulate collagen production, support barrier repair, and reduce visible signs of ageing. It is well tolerated and widely used in anti-ageing serums and creams.
