COSRX - The Blue Peptide Bakuchiol Plump Glow Serum 50ml

COSRX The Blue Peptide Bakuchiol Plump Glow Serum is next-generation anti-aging care built on the synergy of 0.5% copper peptide and 0.25% bakuchiol. It helps improve the look of fine lines, supports elasticity and keeps skin looking firmer and revitalized — while deep hydration leaves it fuller, smoother and naturally radiant. The low-irritation formula is gentle enough for daily use.

Key Benefits

• Fine lines & elasticity: copper peptide and bakuchiol work together for a firmer look.
• Plumping hydration: replenishes moisture for fuller, smoother skin.
• Pores, texture & clarity: gentle daily care for a refined, clear complexion.
• Early-signal care: designed for the first signs — before pores look more pronounced, lines settle and red marks linger.

How to Use

Apply a few drops to clean skin in the morning or evening. Do not use in the same routine with vitamin C, direct acids or retinoids — alternate them on different days or times. Patch testing is recommended before first use. Follow with moisturizer and, in the morning, sunscreen.

Frequently Asked Questions

Why can’t I use it with vitamin C or acids?

Copper peptides are best kept apart from vitamin C, direct acids and retinoids. COSRX recommends using them in separate routines.

Is it suitable for sensitive skin?

The formula is low-irritation for daily use, but patch testing is recommended before first use.

Morning or night?

Either works. Just follow with sunscreen when using it in the morning.

Who is it for?

Anyone noticing early signs of aging — fine lines, loss of bounce, visible pores or lingering red marks.
