Key Benefits and Features

1. Six-Peptide Complex for Targeted Skin Benefits

The serum harnesses a blend of six carefully chosen peptides, each addressing specific needs:

• SH‑Polypeptide‑121 – Promotes collagen synthesis for a plumper, firmer complexion.

• Copper Tripeptide‑1 – Enhances skin texture and supports regeneration.

• Dipeptide Diaminobutyroyl Benzylamide Diacetate – Helps control excess sebum and refines pore appearance.

• Oligopeptide‑68 – Brightens and illuminates the skin tone.

• Palmitoyl Tripeptide‑8 – Soothes irritation and reinforces the skin’s sensitivity threshold.

• Acetyl Hexapeptide‑8 – Smooths fine lines and supports elasticity.

2. Hydrating and Soothing Essentials

Includes hydrating agents like niacinamide and sodium hyaluronate (hyaluronic acid) to enhance glow and moisture, while panthenol helps strengthen the skin barrier and calm irritation.

3. Lightweight, Water‑like Texture

With a thin, non‑greasy, toner‑like consistency, the serum layers seamlessly under other products, making it ideal for multi‑step routines and humid climates.4. Enhances Skin Routine Performance

Used as the very first step after cleansing, it preps the skin to better absorb and maximize the efficacy of subsequent serums, ampoules, and creams.

5. Visible Improvements Reported

• Many users—and skincare experts—note firmer, bouncier, and more hydrated skin with regular use.

• One review shared dramatic results in skin radiance and texture, especially when paired with other COSRX products like Snail 92 All‑in‑One Cream.

• Another user claimed they looked “15 years younger” after consistent use, appreciating its effectiveness across fine lines, moisture, firmness and radiance.

How to Use

1. After cleansing, apply 2–3 pumps of the booster onto skin while still damp.

2. Gently pat to aid absorption.

3. Layer it under your regular serums, ampoules, or moisturizer. For added impact, re‑apply itself once or twice.

4. Frequency: Safe for daily use—both AM and PM routines. Can be paired with vitamin C or retinoids.

Feedback from Users

• Some skin‑care communities valued its hydrating, lightweight feel:

  “Really hydrating and has brightened my skin. Think it’s best used as a first‑step essence.”

• Others noted potential drawbacks, such as mild pilling or clogged pores depending on routine pairing:

  
  “It is good, makes the skin firm… but too bad it does clog pores and sits on top of my skin.”
