COSRX 6 Peptide Collagen Booster Toner Serum is a first-step serum formulated with six potent peptides that enhance overall skin condition and prep the complexion before other treatments. This 2-pack set includes 2 bottles of 150mL each plus 2 travel-size 30mL bottles. The formula targets multiple skin concerns including excess sebum and pore control, brightening, soothing, firming, fine line reduction, and collagen boosting.

The six peptides include SH-Polypeptide-121 for collagen boosting and plumping, Copper Tripeptide-1 for retexturizing and wound healing, Dipeptide Diaminobutyroyl Benzylamide Diacetate for excess sebum and pore care, Oligopeptide-68 for brightening and fading pigmentation, Palmitoyl Tripeptide-8 for soothing and reducing skin sensitivity, and Acetyl Hexapeptide-8 for smoothing fine lines and enhancing firmness. The serum also contains niacinamide for brightening and anti-acne benefits, sodium hyaluronate for intense hydration, adenosine for anti-inflammatory and barrier repair properties, and acetyl glucosamine for additional brightening and wrinkle reduction.

The lightweight formula is fragrance-free and essential oil-free, making it suitable for all skin types including sensitive skin. After cleansing, apply this serum as the first step of your skincare routine, spreading it on the entire face and applying several times to amplify the effect of subsequent serums or ampoules.
