Pure Adenosine

Adenosine is a naturally occurring purine nucleoside and one of the most widely used anti-ageing actives in cosmetic science. It helps improve the look of firmness and elasticity and smooth the look of fine lines and wrinkles — without the irritation or photosensitivity associated with retinoids, making it suitable for all skin types including sensitive.
