Adenosine vs Vitamin C
Two popular actives, side by side — no fluff.
Adenosine
aka adenosine triphosphate
Adenosine is one of the most quietly effective anti-aging ingredients in K-beauty. Approved by Korean regulators as a functional anti-wrinkle ingredient, it's found in an enormous number of products but rarely featured on the front label. It smooths fine lines, promotes wound healing, and has anti-inflammatory properties.
Vitamin C
aka L-ascorbic acid, ascorbic acid, ascorbyl glucoside
Vitamin C is one of the most thoroughly researched antioxidants in dermatology. It neutralizes free radicals, inhibits melanin production, and supports collagen synthesis. The challenge is formulation stability — L-ascorbic acid oxidizes easily, and many products degrade before you finish the bottle.
