Core Product Details

A Hydro-Glow Serum for Firmer, Plumper, More Resilient Skin

COSRX The Blue Peptide Bakuchiol Plump Glow Serum delivers concentrated early-aging care through an elegant, lightweight texture that absorbs without heaviness. Powered by Copper Tripeptide-1 and Bakuchiol, the fluid serum helps visibly improve skin density, firmness, and elasticity while refining the appearance of pores, uneven texture, and dark spots. The result is a smoother, bouncier complexion with the fresh luminosity of a polished Korean glass-skin ritual.

0.5% Copper Tripeptide-1 for Firmness and Visible Vitality

The formula contains 5,000ppm of Copper Tripeptide-1, also known as GHK-Cu. This naturally blue-hued peptide supports the appearance of skin resilience while helping address early visible signs of aging. It gives the serum its distinctive blue tone and makes the treatment especially appealing for complexions that appear tired, less firm, or lacking their former bounce.

0.25% Bakuchiol for Gentle Texture and Elasticity Care

Bakuchiol at 2,500ppm offers plant-derived conditioning care for skin concerned with texture, pores, firmness, and radiance. Often selected as a gentler alternative to retinol, it supports smoother-looking skin while remaining approachable for sensitive complexions and beginners building an early-aging routine. Paired with copper peptides, it creates a sophisticated treatment without the weight of a traditional rich serum.

A Multi-Peptide Complex for Smoother, Bouncier-Looking Skin

A blend of targeted peptides works through multiple pathways to improve the visible look of firmness and texture. Acetyl Hexapeptide-1, Acetyl Heptapeptide-4, Acetyl Hexapeptide-8, Acetyl Octapeptide-3, and Dipeptide Diaminobutyroyl Benzylamide Diacetate complement Copper Tripeptide-1, helping the complexion appear more refined, energized, and resilient with consistent use.

Collagen and Five Hyaluronic Acids for Deeply Cushioned Hydration

Hydrolyzed Collagen and a multi-molecular Hyaluronic Acid complex replenish moisture and help create a fuller, smoother-looking surface. Sodium Hyaluronate, Hyaluronic Acid, Sodium Hyaluronate Crosspolymer, Hydrolyzed Hyaluronic Acid, and Sodium Acetylated Hyaluronate work together to attract and retain hydration, softening the appearance of fine dehydration lines while giving skin a supple, glass-like finish.

Niacinamide for Brighter Tone and Dark-Spot Care

Niacinamide helps improve the appearance of uneven tone, dullness, and dark spots while supporting a visibly clearer complexion. Adenosine complements the serum with smoothing care, while Panthenol, Betaine, Beta-Glucan, and Tocopherol help soothe and protect skin exposed to everyday environmental stress. This balance of brightening, firming, and comforting ingredients makes the serum suitable for consistent daily care.

A Lightweight Serum Made to Layer Beautifully

The fluid consistency glides easily over the complexion and absorbs with a soft, even finish rather than a sticky coating. Apply it after toner and before moisturizer, allowing the formula to settle before sunscreen or makeup. It may be used morning or evening, although highly concentrated Vitamin C treatments should be reserved for a separate routine.

Let Every Blue Drop Restore the Bounce and Glow Your Skin Remembers

There is quiet luxury in a serum that feels almost weightless yet leaves the complexion looking deeply replenished. COSRX The Blue Peptide Bakuchiol Plump Glow Serum melts into the skin with copper peptides, Bakuchiol, collagen, and layered hydration, transforming daily care into a deliberate ritual of resilience. Every application helps reveal skin that feels smoother, appears firmer, and glows with luminous, glass-like vitality.
