COSRX The Blue Peptide Bakuchiol Plump Glow Serum 50mL

A peptide and bakuchiol serum provides a focused conditioning step for skin that looks less firm, dehydrated or uneven. Its place is after cleansing and toning, when a lightweight formula can be spread across the face before the remainder of a skincare routine. Benefits are about visible skin appearance rather than a medical treatment.

COSRX The Blue Peptide Bakuchiol Plump Glow Serum combines a naturally blue copper peptide with bakuchiol and five other peptides. The fluid formula also contains collagen, multiple forms of hyaluronic acid and niacinamide, bringing hydration, texture and tone care together in a 50mL bottle.

Copper Peptide, Bakuchiol and Hydrating Ingredients

This multi-ingredient formula focuses on a plump, luminous finish while remaining lightweight. The blue hue comes from its copper peptide ingredient, and the full ingredient list offers more detail than the highlighted actives alone.

• 0.5% Copper Tripeptide-1: Also identified as GHK-Cu, this naturally blue-hued ingredient is included at 5,000ppm. COSRX positions it for the appearance of skin resilience, firmness and early visible signs of aging.
• 0.25% bakuchiol: The formula contains 2,500ppm of this plant-derived ingredient. It supports the product’s texture and radiance care, alongside the copper peptide, without being presented as a prescription retinoid.
• Five additional peptides: The supporting peptide blend complements Copper Tripeptide-1 in the formula. Its role is to help improve the appearance of firmness and texture within this multi-action skincare step.
• Collagen and five forms of hyaluronic acid: Hydrolyzed collagen and the hyaluronic acid blend are part of the serum’s approach to hydrated, plump-looking skin. Panthenol and betaine also feature in the ingredient list.
• Lightweight fluid texture: The serum spreads from the center of the face outward. Niacinamide and tocopherol join the conditioning blend, creating a formula aimed at uneven-looking tone, texture and a luminous finish.

A Hydrated, Bouncy-Looking Finish

The serum’s benefits combine hydration with visible refinement. It is intended for concerns such as a less firm-looking complexion, enlarged-looking pores and uneven tone, without promising to erase pores or reverse aging.

• Plumper-looking skin: The hydrating formula helps skin look bouncy and fresh. Its collagen and hyaluronic acid ingredients support the moisture-focused character of the product rather than adding a heavy cream texture.
• More refined-looking texture: Bakuchiol and the peptide blend contribute to care for the appearance of pores and uneven texture, helping create a smoother-looking surface and a more polished finish.
• Firmer-looking appearance: Copper peptide and the additional peptides are central to COSRX’s positioning for early visible signs of aging and skin that looks less resilient or firm.
• More luminous tone: Niacinamide is included as part of the formula’s approach to uneven-looking tone. The serum is designed to support radiance alongside its texture and hydration benefits.
• Easy spreading: The lightweight, fluid feel makes application straightforward. Use it at a different time of day from high-concentration vitamin C so that the routine follows COSRX’s specific compatibility guidance.
