COSRX Niacinamide 15% Peptide Booster Set

• COSRX combines two of skincare's most effective actives — 15% Niacinamide and multi-peptide complex — in this Booster Set for a comprehensive approach to brightening, pore refinement, and anti-aging in one targeted bundle.

• Skin Types: All skin types

• Skin Concerns: Enlarged pores, hyperpigmentation, dullness, fine lines, uneven skin tone

• Item Form: Serum set

• Package Description: Niacinamide 15% serum + Peptide Booster (sizes vary)

• 15% Niacinamide (Vitamin B3) visibly minimizes pore appearance, controls sebum, fades dark spots, and brightens overall skin tone.

• Peptide complex supports collagen production and skin elasticity, targeting fine lines and improving skin firmness over time.

• Combining niacinamide and peptides creates a synergistic anti-aging and brightening effect greater than either ingredient alone.

• COSRX's clean formulation approach ensures high concentrations of actives without unnecessary fillers or irritants.
