Core Product Details

A Double 10% Concentration for Skin That Looks Awake & Refined

COS DE BAHA CN Serum brings together 10% caffeine and 10% niacinamide in a high-potency South Korean formula designed to awaken the appearance of tired, uneven-looking skin. While caffeine targets the look of puffiness and under-eye darkness, niacinamide works across the complexion to improve visible tone, texture and clarity. The pairing gives this Korean brightening serum an intriguing dual identity: an energizing treatment for fatigued-looking areas and a refining daily serum for skin craving a fresher, smoother and more luminous appearance.

10% Caffeine Awakens Tired-Looking Skin

Caffeine sits at the heart of CN Serum at a verified 10% concentration. COS DE BAHA specifically positions the ingredient for reducing the appearance of puffiness and dark circles while promoting a more refreshed, energized look. The serum can be applied around the eye area with appropriate care or across the face, making it particularly versatile for mornings when the complexion looks fatigued and for daily rituals devoted to maintaining a brighter, more vital appearance.

10% Niacinamide Refines Tone, Pores & Texture

Niacinamide matches caffeine at an equally concentrated 10%. This beloved Vitamin B3 derivative gives CN Serum its broader complexion-refining character, with COS DE BAHA positioning it to improve uneven-looking tone, visible pores and skin texture while supporting the skin barrier. Together, caffeine and niacinamide create a concentrated K-Beauty treatment for anyone seeking the polished clarity of skin that looks smoother, more balanced and naturally illuminated.

Two Forms of Hyaluronic Acid Drench Skin in Lightweight Moisture

Hydration provides the sensorial counterpoint to the concentrated actives. Sodium hyaluronate and hydrolyzed hyaluronic acid are both present in the verified formula, helping attract moisture and encourage a softer, plumper-looking complexion. Betaine and panthenol further support the serum's moisturizing character, while allantoin adds skin-conditioning care. The result is hydration that feels beautifully weightless rather than occlusive—ideal beneath moisturizer, sunscreen and makeup.

Ferulic Acid & Botanicals Complete the Complexion Ritual

Ferulic acid adds antioxidant-focused care to the formula, while mugwort, lemon balm, lavender flower, Damask rose and green tea extracts complete its botanical composition. These supporting ingredients turn a seemingly simple caffeine-niacinamide pairing into a more layered Korean skincare experience, balancing concentrated actives with humectants, conditioners and plant extracts for skin that feels cared for as it appears increasingly refreshed.

A Clear, Watery Texture Made for Effortless Layering

COS DE BAHA describes CN Serum as having a clear, watery texture that absorbs quickly. Used after cleansing and toning and before moisturizer, it slips easily into both morning and evening skincare routines without introducing unnecessary heaviness. This lightweight character also makes it particularly appealing beneath daytime skincare and makeup, where hydration, smoothness and a fresh-looking finish can create a beautifully prepared canvas.

Awaken the Radiance of a More Energized Korean Beauty Ritual

Made in South Korea, COS DE BAHA CN Serum transforms the signs of a tired-looking complexion into an invitation for renewed luminosity. Concentrated caffeine and niacinamide meet dual hyaluronic acid hydration, panthenol and botanical care in a serum that feels fresh, fluid and effortless against the skin. Morning or evening, each application becomes a small act of devotion to a complexion that looks awake, refined, hydrated and irresistibly alive with radiance.
