The COSRX The 6 Peptide Skin Booster Serum is a highly popular serum designed to drastically improve skin texture, elasticity, and radiance. This ultra-lightweight, water-like serum functions as a hybrid between a toner and a booster. It prepares the skin barrier to absorb subsequent active ingredients more deeply

Key Ingredient Breakdown

The formula combines three major powerhouse categories to target multiple skin concerns at once: 

• 6 Peptide Complex: Features SH-Polypeptide-121 to boost collagen, Copper Tripeptide-1 to retexturize, Acetyl Hexapeptide-8 to smooth fine lines, Dipeptide Diaminobutyroyl Benzylamide Diacetate for oil control, Oligopeptide-68 to brighten, and Palmitoyl Tripeptide-8 to minimize redness.

• Niacinamide: Works to calm inflammation, manage excess sebum, and fade hyperpigmentation or dark spots.

• Hyaluronic Acid: Delivers lightweight, deep hydration to plump parched skin cells.

• Supporting Actives: Contains Adenosine for wrinkle-smoothing and Allantoin to soothe irritated skin barriers
