What's inside ·

PEPTIDE-132, the repair molecule

Peptides are short chains of amino acids that act as chemical messengers inside the skin. When applied topically, they mimic the signals that trigger collagen synthesis, essentially nudging the skin into repair mode. In COSRX PEPTIDE's oil, Peptides targets dehydration, delivering smooths rough texture for a refined, even surface with consistent use.

Ingredients

PEPTIDE-132 and nutrient-rich plant oils in a lightweight bonding oil serum.

Damaged hair often looks dull and frizzy because the cuticle becomes rough and the protein structure weakens over time from heat, coloring, and mechanical stress. A bonding oil serum is designed to address both surface feel and visual finish at once. PEPTIDE-132 is positioned here as the key bonding-care ingredient, helping support the look of stronger, better-sealed strands, while plant oils create a lightweight protective layer that reduces roughness and improves shine.

The texture is important because heavier oils can make fine or damaged hair feel coated. A lighter oil serum spreads more thinly, helping it smooth the cuticle and reduce frizz without leaving sticky residue. When the cuticle lies flatter, hair reflects light more evenly, which makes it look shinier and feel softer. In practical use, the formula works as a finishing and protective step: it helps seal in softness, reduces the appearance of damage, and leaves hair looking glossier and more polished without sacrificing movement.
