Adenosine is a powerhouse anti-aging ingredient naturally found in the body and widely used in Korean skincare for its firming and wrinkle-smoothing effects. It works by energizing skin cells and boosting collagen and elastin production, helping to reduce the appearance of fine lines and improve overall skin elasticity. Beyond its anti-aging benefits, adenosine also soothes and calms the skin, making it suitable even for sensitive types. The result is a smoother, plumper, and more revitalized complexion with a healthy, youthful glow.
