Yes! This will work for you. 14-days money-back guarantee.
COSRX The 6 Peptide Skin Booster Serum is a lightweight first step treatment designed to target multiple early skin concerns including fine lines, uneven texture, dullness, dehydration, enlarged pores, and loss of firmness. Formulated with a powerful 6 Peptide Complex alongside hydrating and barrier supporting ingredients, this multi concern serum helps improve overall skin condition while preparing the skin for the rest of your skincare routine.
Unlike heavy anti aging treatments that can feel rich or overwhelming on the skin, this booster serum features an ultra lightweight toner like texture that absorbs quickly without stickiness or residue. The formula helps support smoother, firmer, and healthier looking skin while enhancing hydration and skin comfort throughout the day.
The serum combines six different peptides that work together to support elasticity, skin texture refinement, pore appearance, hydration balance, and skin resilience. Additional ingredients including niacinamide, hyaluronic acid, allantoin, and adenosine help brighten dull skin, maintain moisture retention, and support smoother looking skin over time.
Designed for all skin types including sensitive and acne prone skin, the COSRX 6 Peptide Booster Serum integrates easily into both beginner and advanced skincare routines. It layers comfortably with ingredients such as vitamin C, retinol, hydrating serums, and moisturizers, making it ideal for preventative skincare and long term skin maintenance.
Clinical testing shared by COSRX reported improvements in hydration, texture, radiance, and skin density with continued use.
