COSRX The 6 Peptide Skin Booster Serum 150ml

📜 The Lowdown

The COSRX The 6 Peptide Skin Booster Serum is an all-in-one first-step serum engineered to unlock your skin's full potential. Powered by a potent blend of six distinct peptides, this weightless, water-like formula acts as a total skin enhancer—tackling everything from enlarged pores and excess sebum to fine lines, rough texture, and loss of firmness. Applied right after cleansing, it primes your skin matrix, allowing every subsequent product in your routine to absorb deeper and perform significantly better.

🧬 Why It’s Different (and why your skin needs it)

• 6-Peptide Power Complex: Features 6 specialized peptides that each target a specific skin concern: SH-Polypeptide-121 (collagen boost), Copper Tripeptide-1 (texture & repair), Dipeptide Diaminobutyroyl Benzylamide Diacetate (wrinkle care), Acetyl Hexapeptide-8 (smoothness), Oligopeptide-68 (brightening), and Palmitoyl Tripeptide-8 (soothing).
• First-Step Absorption Booster: Works as a lightweight prep serum that opens up the skin barrier's pathways, drastically improving the absorption rate of your serums, ampoules, and creams.
• Oil-Free, Water-Light Texture: Glides on like water without a drop of stickiness or weight, making it suitable for layering even under heavy morning and night products.
• Comprehensive Multi-Care: Addresses oiliness, loss of elasticity, uneven tone, dullness, and dehydration all in a single step—eliminating the need to layer multiple single-ingredient serums.

🏆 Why It's a Winner for Your Routine

• Force Multiplier for Skincare: Makes every product you apply after it work twice as hard, giving you faster results from your existing routine.
• Jumbo 150ml Size: Comes in a massive bottle compared to traditional 30ml serums, giving you unbelievable long-term value for daily morning and night application.
• Universal Compatibility: Hypoallergenic and non-comedogenic, making it a seamless addition to any routine regardless of your skin type, age, or sensitivity level.
