COSRX 6 Peptide Skin Booster Serum: Your First Step to Firmer, Younger-Looking Skin

Peptides have earned their place as skincare royalty, and for good reason. These tiny protein fragments communicate with your skin cells, signalling them to produce more collagen, repair damage, and basically act younger. The COSRX 6 Peptide Skin Booster Serum takes this science and packs six different peptides into one lightweight, fast-absorbing formula that preps your skin for everything that comes next.

Korean skincare brand COSRX (short for "Cosmetics + Prescription") has spent over a decade perfecting effective, no-nonsense formulations. The COSRX Serum continues that legacy, offering a multi-tasking booster serum that addresses firmness, fine lines, texture, pores, and dullness all at once.

Why Six Peptides Are Better Than One

Different peptides do different things for your skin. Rather than relying on a single peptide to handle everything, the COSRX 6 Peptide Skin Booster Serum combines six carefully selected peptides, each targeting a specific skin concern. The result? Comprehensive anti-aging care that works on multiple fronts simultaneously.

The Booster Serum functions as your first step after cleansing, prepping skin to absorb better whatever comes next. Think of it as a primer for your serums and moisturisers, amplifying their benefits while delivering its own powerful dose of skin-renewing ingredients.

The Six Peptides and What They Do

Acetyl Hexapeptide-8 (Argireline): Often called "Botox in a jar," Argireline helps relax facial muscles, reducing the appearance of expression lines and wrinkles. Supports collagen production for firmer skin.

Copper Tripeptide-1 (GHK-Cu): A wound-healing powerhouse that stimulates collagen and elastin production. Improves skin texture, firmness, and clarity while providing antioxidant and anti-inflammatory benefits.

sh-Polypeptide-121: Boosts collagen synthesis to help maintain skin's structural integrity and youthful bounce.

Dipeptide Diaminobutyroyl Benzylamide Diacetate (SYN-AKE): A "snake venom" peptide that mimics the muscle-relaxing effects of certain snake venoms. Helps smooth fine lines by reducing micro-muscle movements.

Oligopeptide-68: A brightening peptide that works on skin pigmentation by inhibiting melanin production. Helps achieve a more even, radiant skin tone.

Palmitoyl Tripeptide-8: A calming peptide that soothes inflammation and irritation, particularly helpful for skin stressed by UV exposure or environmental aggressors.

Additional Power Ingredients

Niacinamide: A multitasking superstar that strengthens the skin barrier, reduces acne, fades hyperpigmentation, and minimizes pore appearance. Works beautifully alongside peptides.

Adenosine: An anti-aging ingredient that boosts collagen production and helps reduce the appearance of fine lines and wrinkles.

Sodium Hyaluronate: A smaller form of hyaluronic acid that penetrates deeper to deliver intense hydration from within.

Allantoin: Soothes and protects skin while promoting healing. Particularly helpful when using active ingredients.

Amino Acids Complex: Includes serine, alanine, glycine, threonine, arginine, and proline. These building blocks of proteins support skin's natural repair processes and maintain hydration.

Vitamin E (Tocopherol): An antioxidant that protects skin from free radical damage while nourishing and conditioning.

Benefits You Can Expect

The COSRX 6 Peptide Skin Booster Serum delivers multiple benefits with consistent use:

Reduced Fine Lines and Wrinkles: The combination of muscle-relaxing and collagen-boosting peptides works to smooth existing lines while preventing new ones from forming.

Improved Firmness and Elasticity: Peptides signal your skin to produce more collagen and elastin, resulting in bouncier, more resilient skin over time.

Refined Pores and Texture: Regular use helps minimise the appearance of enlarged pores while smoothing overall skin texture.

Brighter, More Even Tone: Oligopeptide-68 and niacinamide team up to fade dark spots and hyperpigmentation, leaving skin more radiant.

Intense Hydration: Hyaluronic acid and amino acids ensure skin stays plump and moisturised without any sticky residue.

Calmed, Soothed Skin: Anti-inflammatory peptides and allantoin keep irritation at bay, making this serum suitable even for sensitive skin.

How to Use COSRX 6 Peptide Skin Booster

Getting the most from your COSRX Serum is straightforward:

1. Cleanse your face thoroughly and pat dry.
2. Dispense 2-3 pumps of the Booster Serum onto your palm.
3. Gently spread and massage across your face and neck, avoiding the eye area.
4. Pat lightly until fully absorbed (the lightweight formula sinks in quickly).
5. Follow with your regular serums, moisturiser, and sunscreen during the day.
6. Use morning and evening for optimal results.
