Core Product Details

A Concentrated 15% Vitamin C Ritual for Captivating Radiance

COS DE BAHA VA Vitamin C 15 Serum envelops the complexion in a focused South Korean skincare ritual created for skin that has lost some of its natural luminosity. At its heart lies 15% L-ascorbic acid, a pure form of vitamin C prized for antioxidant care and its ability to improve the appearance of dullness and uneven pigmentation. Lightweight and effortlessly layerable, this Korean vitamin C serum brings high-performance brightening care into the intimacy of a daily beauty ritual, leaving the complexion looking smoother, clearer and increasingly radiant.

Pure Vitamin C & Arbutin for Uneven Tone and Dark Spots

The formula pairs concentrated L-ascorbic acid with arbutin to create targeted care for visible dark spots, post-acne marks and uneven-looking skin tone. Vitamin C helps illuminate lacklustre skin while supporting a more refined, youthful-looking complexion, while arbutin complements the formula's tone-evening focus. With consistent use, this brightening Korean serum helps reveal the impression of greater clarity and luminosity—the coveted glow that makes bare skin itself feel like the most exquisite finishing touch.

Hydration Woven into High-Performance Brightening Care

Concentrated actives meet a more comforting side through panthenol, sodium hyaluronate and aloe vera. Panthenol, also known as vitamin B5, provides conditioning support, while sodium hyaluronate helps attract moisture for skin that feels supple and hydrated. Aloe vera further complements this moisture-conscious composition. The result is a fluid, lightweight serum that absorbs readily and slips elegantly beneath moisturizer, making sophisticated active skincare feel beautifully at home within a layered K-Beauty routine.

Antioxidant Care with a Botanical Korean Skincare Touch

Green tea, bitter melon, elderflower and edelweiss extracts complete the composition, bringing additional botanical and antioxidant character to the formula. This marriage of a potent hero active with supporting hydrators and plant extracts reflects the ingredient-focused philosophy of modern skincare from South Korea: purposeful formulas designed to address visible concerns while preserving the pleasure of the ritual. The serum is especially compelling for those seeking Korean skincare for hyperpigmentation, dull skin, post-blemish marks and a brighter, more even-looking complexion.

A Morning or Evening Ritual Designed Around Your Glow

After cleansing and toning, smooth a small amount or 1–2 drops over the complexion before moisturizer. Because 15% L-ascorbic acid is a concentrated active, those new to pure vitamin C should begin thoughtfully, patch testing first and adjusting frequency according to skin tolerance. Used in the morning, the serum should be followed by sunscreen. Used at night, it becomes an elegant radiance step between toner and moisturizer—a simple moment of indulgence dedicated entirely to the complexion.

Preserving the Freshness of Pure Vitamin C

L-ascorbic acid deserves considered care within the beauty cabinet. COS DE BAHA recommends using the serum within six months of opening, while keeping it tightly closed and protected from excessive heat and direct sunlight helps safeguard its freshness. It is a small act of ritualistic care for a formula centered on one of skincare's most celebrated antioxidants.

Where Korean Precision Meets the Art of Luminosity

Made in South Korea, COS DE BAHA VA Vitamin C 15 Serum captures the seductive simplicity of a ritual in which every drop has purpose. Its combination of pure vitamin C, arbutin, vitamin B5, sodium hyaluronate and botanical extracts turns everyday brightening care into something more intimate: a commitment to skin that looks polished, luminous and beautifully alive. For the beauty devotee who considers radiance an essential part of their presence, this is K-Beauty designed not simply to be applied, but savoured.
