Adenosine vs Salicylic Acid
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.
Salicylic Acid
aka BHA, beta hydroxy acid, 2-hydroxybenzoic acid
Salicylic acid is the only commonly used BHA in skincare, and its oil-solubility is what makes it special. It can penetrate into pores to dissolve the sebum and dead cells that cause blackheads and breakouts — something water-soluble AHAs simply can't do.
