COSRX The 6 Peptide Skin Booster Serum 150ml

The COSRX The 6 Peptide Skin Booster Serum is a powerhouse, multi-benefit "first serum" (or prep serum) designed to target multiple skin concerns at once. Instead of focusing on just one active ingredient, it combines six different peptides to act as a comprehensive skin booster that amplifies the results of anything you apply on top of it.

🌟 Key Benefits

1. Multi-Dimensional Anti-Aging

• Firms & Plumps: It stimulates collagen production to improve overall skin elasticity, helping to firm up sagging areas and restore a youthful bounce.
• Smooths Fine Lines: By targeting the micro-muscles and structural integrity of the skin, it helps soften the appearance of expression lines, crow's feet, and fine wrinkles.

2. Refines Skin Texture & Pores

• Minimizes Pore Appearance: It helps tighten and refine the look of enlarged pores by strengthening the skin matrix surrounding them.
• Smooths Roughness: It promotes gentle cellular turnover, leaving the skin texture feeling remarkably smooth, soft, and even.

3. Brightens & Evens Skin Tone

• Fades Hyperpigmentation: The formulation actively works to clarify the complexion, reducing the appearance of dark spots, post-acne marks, and dullness for a more radiant glow.

4. Deep Hydration & Barrier Support

• Locks in Moisture: It delivers an immediate wave of weightless hydration, quenching dehydrated skin and plumping it from within.
• Soothes & Calms: It aids in repairing a compromised skin barrier, reducing redness and irritation.

5. Ultimate Booster (Enhances Other Skincare)

• Prep Step Efficiency: Designed to be used as the very first step after cleansing, its ultra-lightweight texture enhances the absorption and efficacy of subsequent serums (like Vitamin C, Niacinamide, or Retinol).

🧪 The Science: The 6-Peptide Complex

Each peptide in this 4.7% complex is chosen to tackle a specific skin concern:

1. SH-Polypeptide-121 (Collagen Boosting): Plumps the skin and promotes elasticity.
2. Copper Tripeptide-1 (Texture Retexturizing): Smooths uneven skin and helps repair damaged tissue.
3. Acetyl Hexapeptide-8 (Wrinkle Smoothing): Often called "Botox in a bottle," it helps relax facial tension to soften fine lines.
4. Palmitoyl Tripeptide-8 (Soothing & Calming): Reduces skin sensitivity and calms inflammation or redness.
5. Palmitoyl Pentapeptide-4 (Firming): Strengthens the skin structure to reduce wrinkle depth.
6. Oligopeptide-68 (Brightening): Targets melanin production to brighten dullness and even out tone.
7. Supporting Ingredients: Enriched with Niacinamide (for brightening and sebum control), Adenosine (for cellular energy and anti-inflammation), and Hyaluronic Acid / Allantoin (for deep hydration).

💧 Texture and Application

• The Feel: It has a water-like, incredibly lightweight, and non-sticky consistency. It absorbs almost instantly into the skin without leaving any heavy residue.
• How to Use: Apply 2–3 pumps onto clean skin immediately after cleansing (before toner or as your toner step). Because it is highly stable, it pairs beautifully with all actives, including Retinol, Vitamin C, and AHAs/BHAs, without causing irritation.
• Skin Types: Suitable for all skin types, including oily and acne-prone skin (due to its weightless, non-comedogenic texture) and highly sensitive skin (it is fragrance-free and hypoallergenic).
