Cosrx The 6 Peptide Skin Booster Serum 30 ml

COSRX The 6 Peptide Skin Booster Serum 30 ml is a lightweight Korean skin booster designed to support your skin before the rest of your routine. Rather than a traditional treatment serum, it delivers hydration and multiple peptides that help improve firmness, smoothness, and overall resilience — ideal for fine lines, enlarged pores, uneven texture, or loss of elasticity.

Powered by COSRX’s signature 6 Peptide Complex alongside Niacinamide, Hyaluronic Acid, Panthenol, and Allantoin, this fast-absorbing, non-sticky formula improves the appearance of wrinkles, refines texture, and strengthens the skin barrier. Built on Multi-Peptide Technology and Skin Booster Technology, it’s suitable for beginners and experienced users alike, layering easily with Vitamin C, retinol, moisturizers, and sunscreen as the ideal first treatment step in a daily K-Beauty routine.

Key Benefits

•           Supports firmer-looking skin – improves the appearance of elasticity over time

•           Reduces fine lines – softens early wrinkles for a smoother, youthful look

•           Strengthens the skin barrier – Panthenol, Allantoin, and peptides reduce moisture loss

•           Lightweight hydration – Hyaluronic Acid keeps skin soft, plump, and comfortable

•           Refines texture and pores – smooths rough texture for a more refined complexion

•           Brightens dull skin – Niacinamide improves clarity and evens tone

•           Layers easily – watery, fast-absorbing texture pairs with Vitamin C, retinol, and peptide creams

Key Ingredients

The 6 Peptide Complex is the core of this formula: Copper Tripeptide-1 supports firmness and resilience; Acetyl Hexapeptide-8, an expression-line peptide, softens fine lines; Palmitoyl Tripeptide-5 supports collagen-rich, firmer-looking skin; Palmitoyl Tripeptide-8 conditions skin for added comfort; Palmitoyl Pentapeptide-4 targets wrinkles and texture; and SH-Polypeptide-121 supports overall skin renewal.

Supporting ingredients include Niacinamide for brightening and clarity, Hyaluronic Acid for lasting hydration, Panthenol and Allantoin to soothe and reinforce the moisture barrier, and Adenosine to further smooth fine lines.

Product Specifications

Skin Type Suitability

Suits normal skin for everyday maintenance, dry skin through lightweight hydration and barrier support, and oily skin thanks to its watery, fast-absorbing feel. Combination skin benefits from balanced moisture, while Panthenol and Allantoin make it comfortable for sensitive skin. Mature skin benefits most from its firmness- and elasticity-supporting peptides. Avoid if you have known allergies, broken or infected skin, or are pregnant/breastfeeding — consult a professional first.

How To Use

Apply as the first treatment step after toner: dispense 2–3 pumps and pat gently over the face and neck until absorbed, then follow with your treatment serum (Vitamin C, retinol, or brightening serum) and moisturizer. Suitable for daily morning and evening use; finish daytime routines with broad-spectrum sunscreen (SPF 30+).

Authenticity

COSRX is a globally recognized Korean skincare brand known for evidence-based, skin-friendly formulations rather than exaggerated claims. To ensure authenticity, buy from an authorized retailer specializing in genuine Korean skincare, and check for the official COSRX logo, batch number, and expiry date.
