The 6 Peptide Skin Booster Serum

Cosrx - The 6 Peptide Skin Booster Serum is a face serum parent product in the K-beauty category. The listing confirms the Cosrx brand, serum placement, and two size options: 30ml and 150ml. The title identifies the product as a six-peptide skin booster serum, so the description focuses on routine placement and size choice.

Why It Stands Out

The product is specific because it is positioned as a skin booster rather than a basic moisturizer or cleanser. That makes it a middle skincare step for users who want to add a targeted serum before cream, while the two sizes support both trial and longer-term use.

Best For

Best for skincare users comparing Cosrx serum options and wanting a peptide-focused product that can sit after cleansing and toner.

How to Use

Apply after cleansing and toner. Spread across the face, allow it to settle, then follow with moisturizer. Use sunscreen in the daytime routine.

Benefits

• Peptide booster positioning is confirmed by the title.
• Serum format layers before moisturizer.
• 30ml and 150ml sizes support different buying needs.
• K-beauty listing suits routines built around multiple hydration steps.

Good to Know

Pick 30ml if testing the formula or 150ml if you prefer a larger routine size. The listing details does not confirm skin type, texture, or ingredient percentages.
