Hyaluronic Acid vs Snail Mucin
Two popular actives, side by side — no fluff.
Hyaluronic Acid
aka HA, sodium hyaluronate, hyaluronan
Hyaluronic acid is a naturally occurring molecule that can hold up to 1,000 times its weight in water — a claim that's technically true but slightly misleading in skincare context. It's an excellent humectant that draws moisture to the skin, but works best in humid environments or when sealed with an occlusive.
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.
