COSRX The 6 Peptide Skin Booster Serum 150ml

The Core Benefit

Advanced skin health has evolved past reactive defect correction; today, it is about sustaining and optimizing your skin’s natural biological functions from the very first step of your routine. The COSRX The 6 Peptide Skin Booster Serum delivers a high-integrity, mechanism-based approach to skin longevity, working as a cellular facilitator to enhance overall skin resilience and health.

Formulated with an ultra-lightweight, water-based texture, this jumbo-sized booster liquid sinks instantly into the cell architecture without leaving any sticky or heavy film. It serves as an essential priming treatment that cooperates harmoniously with your skin microbiome, balancing sebum, smoothing micro-texture, and dramatically boosting the absorption of any serum applied afterward.

The Science of the 6-Peptide Mechanism

Instead of chasing trend-driven "miracle molecules," this clean formulation utilizes a highly precise blend of six target peptides that work as biochemical messengers to optimize different skin functions:

• SH-Polypeptide-121: Cooperates with the skin structure to promote noticeable plumpness and density.

• Copper Tripeptide-1: Works at a cellular level to refine skin turnover, smoothing out uneven texture and targeting surface marks.

• Acetyle Hexapeptide-8: Targets micro-lines, promoting a relaxed, smooth, and youthfully elastic surface.

• Palmitoyl Tripeptide-5: Significantly enhances skin firmness and builds long-term barrier structural resilience.

• Palmitoyl Tripeptide-1 & Palmitoyl Tetrapeptide-7: Work in tandem to deeply soothe redness, protect against environmental stress, and maintain cellular tranquility.

How to Use & Routine Integration 

To achieve an authentic, natural glow while fully respecting your cutaneous ecosystem, integrate this booster safely into your daily habits:

• How to Apply: Immediately after cleansing, pump an generous amount onto your hands and gently press the liquid into your face and neck until fully absorbed.

• Skin Longevity Tip: Treat this product as your ultimate skin prep. Because it acts as a biological booster, applying it on clean skin optimizes the efficacy of subsequent actives. For a complete structural routine, layer it right before a fermented treatment—like a botanical essence—or a plant-based PDRN serum, locking in deep cell hydration and sealing your barrier for the day.
