Salicylic Acid vs Snail Mucin
Two popular actives, side by side — no fluff.
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.
Snail Mucin
aka snail secretion filtrate, snail extract, Cornu aspersum
Snail mucin is one of K-beauty's most iconic — and most debated — ingredients. The evidence suggests genuine hydrating and wound-healing properties from its glycoprotein, glycolic acid, and hyaluronic acid content, but the clinical data specifically for skin application is more limited than the hype implies.
