Core Product Details

A Dual-Active Ritual for Dark Spots & Luminous Clarity

COS DE BAHA AN Arbutin 5% Niacinamide 5% Serum brings two celebrated complexion-refining actives together in an elegant South Korean skincare ritual. Formulated with 5% arbutin and 5% niacinamide, this lightweight serum is created to help improve the appearance of hyperpigmentation, dark spots and uneven-looking tone while encouraging a brighter, clearer complexion. Its transparent, watery texture absorbs quickly, making concentrated Korean brightening skincare feel effortless enough to become part of both morning and evening rituals.

5% Arbutin for Targeted Hyperpigmentation Care

Arbutin sits at the heart of the formula at a verified 5% concentration. COS DE BAHA positions this ingredient for visible pigmentation, dark spots and discoloration, making AN Serum particularly alluring for complexions that have lost their sense of uniformity. Rather than concealing uneven tone beneath makeup, the formula becomes a daily investment in visibly clearer-looking skin, creating the refined luminosity that makes a bare complexion feel beautifully polished.

5% Niacinamide for Tone, Barrier & Sebum Balance

An equal 5% concentration of niacinamide, or vitamin B3, gives the serum a complementary multi-tasking dimension. According to COS DE BAHA's current product information, niacinamide supports brighter, more even-looking tone while helping strengthen the skin barrier and balance sebum. This pairing makes the formula relevant beyond pigmentation alone, offering a thoughtful Korean niacinamide serum for those seeking clarity, balance and a smoother-looking complexion in one streamlined treatment.

Hyaluronic Acid Wraps Brightening Care in Hydration

Sodium hyaluronate provides the moisture-binding element of the formula, helping skin retain hydration for a softer, more supple appearance. Aloe vera and glycerin further reinforce its moisture-conscious character, while allantoin and dipotassium glycyrrhizate bring additional conditioning support. The result is targeted dark spot care that does not abandon the sensorial pleasure of hydration—skin feels comfortably cared for as the formula focuses on visible tone and luminosity.

Botanical Care Completes the Current Korean Formula

The current manufacturer ingredient list incorporates green tea, bitter melon, elderflower and edelweiss extracts, bringing botanical and antioxidant character to the formula. This combination of concentrated actives, humectant hydration and plant extracts reflects the purposeful layering associated with modern K-Beauty innovation: ingredients chosen not simply for abundance, but to support a complexion that looks balanced, fresh and increasingly radiant.

A Weightless Addition to Morning & Evening Skincare

COS DE BAHA describes AN Serum as clear, watery and quick absorbing, allowing it to disappear elegantly beneath moisturizer rather than competing with the rest of your ritual. After cleansing and toning, smooth an appropriate amount over the complexion before moisturizing. The current manufacturer guidance permits daily AM and PM use for all skin types and recommends sunscreen during the day—an essential companion whenever visible pigmentation is a skincare concern.

Two Brightening Icons, One Ritual of Korean Radiance

Made in South Korea, COS DE BAHA AN Arbutin 5% Niacinamide 5% Serum embodies the beauty of a ritual built around precision. Arbutin focuses attention on visible discoloration while niacinamide brings tone-refining, barrier-supporting and sebum-balancing care; hyaluronic acid surrounds the experience with hydration. Each weightless application becomes an invitation to reveal skin that looks increasingly harmonious, smooth and luminous—the kind of radiance that feels less like something applied and more like something entirely your own.
