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).

Ash vs. Moisture/Success?
Scent: Smoky coffee, Size: 4 Fl Oz (Pack of 1)
The product feels great on the skin and moisturizes well. Although, don't be fooled by the smokey coffee detail. I'm an avid expresso bean grinder and drinker, this is no coffee. Smells like strong chain smokers favorite corner of the house on a stressful day. Imagine ash trays and Jojoba blended. Now that that's explained, it genuinely feels great on the skin/beard/scalp. Unfortunately, I am unsure how long my wife will tolerate this as a nighttime routine.

So far nothing amazing
Scent: Smoky coffee, Size: 4 Fl Oz (Pack of 1)
So I’ve been using for a couple of weeks now and I haven’t noticed any difference. I am going to continue on. I don’t know if it takes time for it to actually show some results. I will say two things about it. It comes solid for 12 my jar cracked and broken And it’s non-returnable so I just have to deal with it so that’s unfortunate after paying $20 second of all it is a solid mass so you have to put it in your hands and kind of warm it up for it to become any sort of an oil and I wouldn’t even consider it an oil at that it’s more of like a cream once you warm it up in your hands, but it doesn’t make your hair greasy. I use a small amount I would think that the jar would last a long time given that you don’t need a lot to get through to your scalp unfortunately, with my jar being cracked, I don’t know how that’s gonna affect the longevity of the product And it does have a smell think of burnt coffee beans that will dissipate after about an hour to an hour and a half after putting it on, but if you’re not putting it on, I’m just going to bed. It might be become an issue. I’m gonna wait it out. I hope I do see results from doing this but again so far nothing.

Wonderful product
Scent: Smoky coffee, Size: 4 Fl Oz (Pack of 1)
I used this on a bald spot I had and it worked extremely well. Consistency is key though it needs to be used every day

It works and I love it!
Scent: Smoky coffee, Size: 4 Fl Oz (Pack of 1)
I love this product.. been using it for a few months now. My hair is more manageable and my thinning crown looks and feels fuller. The smoky smell, am not bothered because it disappears after a few minutes. I use it twice a week, massage very little amount on scalp and hair, then the next day wash it off with shampoo. I used to need to dye my gray every 3 to 4 months when some appear. Now, it's been 4 months since my last visit to the salon. I noticed my hair has darken a bit. I can delay my salon visit for another month unless I need a haircut!! Yehey!
