Core Product Details

Two Brightening Actives, One Refined Korean Complexion Ritual

COS DE BAHA AN Arbutin Niacinamide Serum brings together two celebrated tone-refining ingredients in equal 5% concentrations. Created in South Korea, this concentrated brightening serum pairs arbutin with niacinamide to address the appearance of hyperpigmentation, dark spots and uneven-looking tone while encouraging a clearer, more luminous complexion. Rather than relying on an aggressive resurfacing approach, AN Serum slips elegantly into a daily K-Beauty ritual, surrounding its targeted actives with aloe, humectants and skin-conditioning ingredients for a beautifully balanced treatment. :contentReference[oaicite:0]{index=0}

5% Arbutin Targets the Look of Stubborn Discoloration

Arbutin sits at the heart of AN Serum at a verified 5% concentration. COS DE BAHA specifically positions the formula for pigmentation, melasma and dark spots, making it particularly relevant when lingering discoloration disrupts an otherwise even-looking complexion. With consistent use and diligent daytime sun protection, the serum becomes a focused step for cultivating the refined clarity and luminous uniformity associated with meticulous Korean brightening skincare. :contentReference[oaicite:1]{index=1}

5% Niacinamide Refines Tone, Clarity & Visible Texture

Niacinamide matches arbutin at 5%, adding a multi-dimensional Vitamin B3 component to the formula. Alongside its brightening role, niacinamide supports a more balanced, refined-looking complexion and complements arbutin beautifully for skin affected by uneven tone and post-blemish discoloration. The equal concentrations give AN Serum its defining identity: a targeted Korean arbutin and niacinamide serum rather than a conventional hydrating treatment with trace amounts of brightening actives. :contentReference[oaicite:2]{index=2}

Aloe & Hyaluronic Acid Wrap Brightening Care in Hydration

Aloe Barbadensis Leaf Extract appears first in the renewed ingredient composition, creating a soothing, moisture-conscious foundation for the concentrated actives. Glycerin and sodium hyaluronate help attract and retain surface moisture, while allantoin and dipotassium glycyrrhizate add further skin-conditioning care. This thoughtful supporting system gives AN Serum a more sensorial character: skin is not merely treated for visible discoloration, but left feeling hydrated, comfortable and beautifully cared for. :contentReference[oaicite:3]{index=3}

A Renewed Botanical Complex for Contemporary K-Beauty Care

COS DE BAHA has officially documented a reformulation of AN Serum, replacing the earlier witch hazel and eucalyptus-containing botanical system. The renewed composition features Camellia Sinensis leaf extract, Momordica Charantia fruit extract, Sambucus Nigra flower extract and Leontopodium Alpinum extract. This current botanical complex completes a concise formula that keeps its attention firmly on brightening, hydration and skin-conditioning care. :contentReference[oaicite:4]{index=4}

Effortless Layering for a More Luminous Daily Ritual

After cleansing and toning, apply a small amount of AN Serum and allow it to absorb before sealing the ritual with moisturizer. Its straightforward serum format makes it easy to incorporate into a layered Korean skincare routine alongside hydrating toners, essences and barrier-supporting creams. During daytime use, sunscreen is essential when discoloration is a concern, helping protect the complexion while your brightening routine works toward a more uniform-looking glow.

Let Every Drop Reveal a Clearer, More Luminous Complexion

Made in South Korea, COS DE BAHA AN Arbutin Niacinamide Serum turns targeted dark-spot care into a beautifully uncomplicated act of devotion. Arbutin and niacinamide meet aloe, hyaluronic hydration and a renewed botanical complex in a formula devoted to visible clarity. With each application, the ritual becomes less about concealing unevenness and more about revealing skin that looks smooth, balanced and naturally illuminated.
