Peptides vs Snail Mucin
Two popular actives, side by side — no fluff.
Peptides
aka copper peptides, matrixyl, palmitoyl tripeptide
Peptides are short chains of amino acids that can signal skin cells to produce more collagen and elastin. The category is broad and evidence quality varies dramatically — some peptides (like Matrixyl) have decent clinical data, while many others are supported by little more than in vitro studies and marketing enthusiasm.
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.
