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).

The cold side really works. It's nice ;)
Size: King (2 Pack)
The soft side aspect of it is really awesome. We like the whole cold pillow thing but personally I feel like it keeps my head too high up so I wake up with a neck pain. But for someone who likes support, this would be a perfect option.

Perfect pillow
Size: Queen (2 pack)
Very comfortable! A light firmness yet you sink into the pillow perfectly. Keeps shape. Fluff right back up instantly when you leave it. Supports and the quality is great for the price.

Love these pillows!
Size: Queen (2 pack)
I’m a side and stomach sleeper. I’ve bought so many pillows recently trying to find one that doesn’t kill my neck or shoulder. I felt like I was looking for a unicorn. For some reason this pillow just works. It has a higher loft, which I prefer, but it’s also super squishy, which I also prefer. It somehow has the best of both worlds. They feel high quality, are adjustable in terms of density since you can remove as much filling as you want, they actually fill my pillowcases so they’re not flopping around the pillow, and they maintain their shape after a full night of sleeping on them, the price point for two pillows is just right, and best of all, they actually stay cool. I am a hot sleeper so that last point is worth the cost of entry all by itself. I have no neck or shoulder pain after getting a full night’s sleep on these pillows. The only negative is the initial smell of the pillows. It’s pretty strong, but I’m sure this will lessen over time.
