COSRX The 6 Peptide Skin Booster Serum transforms daily skincare by acting as the ultimate foundational prep step for the face. This water-based formula targets enlarged pores, loss of firmness, and uneven tone while priming the skin to absorb subsequent products more efficiently. A powerhouse blend of six unique peptides regulates excess sebum and smooths rough texture without leaving a sticky residue. The lightweight liquid delivers immediate hydration and balance to create a vibrant, healthy glow. Every application sets the stage for a stronger, more resilient complexion. Why You Will Love It: Multi-Peptide Complex: Combines six unique peptides to address firmness, fine lines, and skin tone in one single step. Texture Refinement: Works to minimise pore appearance and regulate sebum for a smoother, more matte skin surface. Prep and Prime: Functions as a high-performance booster that increases the absorption of subsequent serums or moisturisers. Weightless Hydration: Features a toner-like consistency that provides deep moisture without any greasy or tacky feeling. How to Use: Apply several pumps to the face immediately after cleansing as the very first step of your skincare. Tap the liquid gently into the skin until fully absorbed, repeating the process if your skin feels particularly dry or lacks bounce.
