COSRX The 6 Peptide Skin Booster Serum 150ml

Product Information

The COSRX The 6 Peptide Skin Booster Serum is a revolutionary "first-step" treatment that comes in a generous 150ml bottle—significantly larger than your average serum. Think of this as the "Swiss Army Knife" of skincare; it’s designed to be used immediately after cleansing to prep, treat, and amplify the effects of every product you apply afterward.Instead of targeting just one issue, it uses a complex of six different peptides to address everything from texture and pores to firmness and fine lines.## The "Skin Booster" DifferenceThis isn't a traditional thick serum. It has a watery, toner-like consistency that allows it to vanish into the skin, making it the perfect base for "skin layering."Total Revitalization: It works as an all-in-one solution for skin that feels "tired," inelastic, or congested.Absorption Multiplier: It preps the skin’s surface so that your next serum (like Vitamin C or Retinol) can penetrate more effectively.Non-Sticky Finish: Despite its high performance, it leaves zero residue, making it ideal for oily, combination, and sensitive skin types.Dermatologist Tested: Hypoallergenic and safe for sensitive skin, focusing on comfort and long-term barrier health.### The "6 Peptide" ComplexEach peptide in this $150\text{ml}$ bottle serves a specific architectural purpose for your skin:PeptidePrimary BenefitSH-Polypeptide-121Boosts collagen and increases skin plumpness.Copper Tripeptide-1Refines skin texture and helps with "orange peel" pores.Dipeptide DiaminobutyroylTargets oil control and pore appearance.Oligopeptide-68Brightens the complexion and evens out skin tone.Palmitoyl Tripeptide-8Soothes the skin and reduces sensitivity/redness.Acetyl Hexapeptide-8Helps firm the skin and smooth out fine expression lines.## How to Use: The "First-Step" RuleBecause this acts as a "booster," its placement in your routine is vital:Directly After Cleansing: Apply this as the very first step in your routine (even before toner).Generous Application: Since it comes in a 150ml bottle, don't be afraid to use 2–3 pumps. Pat it gently over the face and neck.The Layering Trick: While your skin is still damp from the booster, apply your next active (like COSRX Snail Mucin or The Ordinary Niacinamide).Frequency: Use morning and night for best results. It plays well with all other active ingredients, including AHAs, BHAs, and Retinol.## Why the 150ml Size?Most serums come in 30ml bottles because they are "spot" treatments. COSRX created this in a 150ml size because it is intended to be used liberally across the entire face, neck, and even chest. It provides a long-term supply for a fundamental step in your daily regimen.
