COSRX – The 6 Peptide Skin Booster Serum (150ml)

VETTING STATUS: PASSED. Verified for multi-pathway dermal support, enhanced active ingredient absorption, and foundational structural reinforcement.

The Curator's Summary: The COSRX 6 Peptide Skin Booster Serum is a high-volume, first-step treatment engineered to prime the epidermis and exponentially increase the absorption rate of all subsequent active ingredients. Formulated with a synergistic matrix of six distinct peptides, this watery serum addresses multiple cellular concerns simultaneously—from structural elasticity and pore refinement to redness reduction and hyperpigmentation. It functions as the ultimate non-conflicting base layer to maximize the efficacy of your entire regimen.

Skin Type: Suitable for all skin types. Highly recommended for those utilizing high-potency actives (like retinol, chemical exfoliants, or Vitamin C) who require a structural buffer and enhanced penetration.

The Clinical Formula:

• 6-Peptide Matrix: A comprehensive blend including Copper Tripeptide-1 (textural refinement), Acetyl Hexapeptide-8 (fine line reduction), and SH-Polypeptide-121 (collagen synthesis). Verified to support the dermal structure from multiple biological angles.

• Niacinamide: Visibly regulates sebum production, refines enlarged pores, and interrupts melanin transfer to unify uneven tone.

• Hyaluronic Acid & Allantoin: Delivers deep, immediate hydration and soothes micro-inflammation, preventing trans-epidermal water loss (TEWL) post-cleanse.

• Water-Light Base: Engineered for rapid, zero-residue absorption. It creates a weightless moisture net that never pills or conflicts with heavier serums and sunscreens.

How to use:

1. Use as the very first step after cleansing (Step 2 or 3). If you use a toner, apply this booster immediately after the toner has absorbed.

2. Dispense 2–3 pumps into your palms and press into the face and neck.

3. The Stacking Tech: While your skin is still damp from this booster, immediately apply your next treatment (e.g., COSRX Snail Mucin). The booster acts as a delivery vehicle for these actives.

4. Use morning and night to maintain a perfectly balanced, clarified, and resilient complexion.
