Why COSRX?
COSRX was born from a single belief: that effective skincare doesn't need a long ingredient list. Every formula is built around one or two hero actives at clinically meaningful concentrations, stripped of unnecessary fragrance, colorants, and fillers. The brand gained global traction not through marketing campaigns but through ingredient-literate skincare communities who recognized the value of 96% snail mucin and 4% betaine salicylate. Today, COSRX sells in over 60 countries and remains one of the most-reviewed K-Beauty brands on Amazon.

Snail Secretion Filtrate 92%A true multitasker — 92% snail mucin layered with niacinamide and panthenol means this gel-cream simultaneously moisturizes, calms inflammation, and accelerates post-breakout healing in one step.

Betaine Salicylate 4%Betaine salicylate — a gentler BHA ester derived from sugar beets — penetrates sebum-filled pores and dissolves plugs without the pH-sensitivity and irritation associated with traditional salicylic acid formulas.

Tea Tree Oil + BHA + pH 5.0A pH of around 5.0 means it cleanses without disrupting the acid mantle, preserving the environment your serums and actives need to actually work — something most cleansers fail to do.
