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).

DURABLE
Size: 2.8in for Small & Medium Dogs
My dog loves these balls almost as much as she loves tennis balls, which she tears up within a day. These two balls have lasted over a week with no signs of wear. I was unsure when I ordered them but they do bounce, not quite like a tennis ball but enough to keep my dog's attention. When using toothpaste in these balls I had to put it deep into the openings or she just licks it off of the surface and when its that deep, it doesn't squeeze out like I think it should. It just stays in the crevasses and gets old and hard. As a ball it's great, as a toothpaste delivery system it's not so great.

Perfect For Sophia!
Size: 1.8in for Puppy Dogs, Size: 1.8in for Puppy Dogs
These little balls are the perfect size for Sophia who is a 7 lb Yorkie with a teeny tiny mouth. The slots in the balls make them very easy for her little teeth to grab hold of and carry. The quality of the rubber is excellent, strong and durable. They're holding up great so far! She loves them and so does her Mama! 5 stars!

Horrible, don't buy
Size: 1.8in for Puppy Dogs
I wanted to love these. They had so much potential. It's a good size. It seems like a good shape. But ... 1) first red flag should have been the packaging. It looked like it was a dollar store item that had beenblost on the shelves for years. 2) the rubber is super flexible. I was expecting it to be sturdier. I can flatten the ball without lich force. Maybe that doesn't matter. Naybe flexible is good. But I never got a chance to test out it's durability against a pup because... 3) it smelled. I expected it to smell like rubber, like most rubber toys. Rubber smell is okay. Usually rubber smell goes away. But, this was NOT a rubber smell. It smells like peppermint or something similar. It's like someone sprayed essential oils when mixing the rubber and now the smell will not leave. I soaked it in dawn soap half the day and overnight. I rubbed. I scrubbed. The smell actually gets worst the more you scrub it!!! It's like a scented marker or scented eraser, but you do NOT want the scent in a dog toy! My dog cannot smell the food in it because the smell of the weird mint-like scent is so overpowering. He saw it had food, and wanted it, but every time he started sniffing wildly, he would recoil. Whoever thought it was a good idea to scent this was WRONG. Mint in the form of an essential oil is extremely poisonous to dogs!! So, why they would put a mint-loke scent ijto the dog's rubber treat toy is beyond me. I would return this if I hadn't throw out the package immediately. I considered pulling the package out of the trash once i realized the scent issue but other trash had already been dumped into the trash can over it and i didn't want to dig through trash. The ball is still soaking in soap. I scrubbed again this morning. I let obe dry out. No luck. It actually seems to get worst the more you scrub, like it really is embedded in the rubber itself. Yuck!!!

Excellent, unless your pup is a dedicated destructo-dog!
Color: Yellow and Orange
I purchased this twice for a young puppy. She loves these slippers, and they are quite resistent to her piranha teeth. The same can't be said for my adult Golden Retriever, who destroys almost every toy; it's one of his missions in life. A slipper accidently found its way to him, and he shredded it within about 45 minutes. I have to say that I'm surprised it lasted that long, attesting to its relative durability. Overall, I recommend these for most dogs.
