What Is Adenosine?

Adenosine is a naturally occurring nucleoside found in every cell of the body that plays a crucial role in cellular energy (ATP). In skincare, adenosine has been clinically validated as an anti-wrinkle ingredient — it stimulates collagen production, accelerates wound healing, and soothes inflammation. Approved by Korea's MFDS as a functional anti-wrinkle ingredient. Works well at low concentrations (0.04-0.1%) and is exceptionally well-tolerated.
