Core Product Details

10% Niacinamide for Pores, Tone & a More Refined Complexion

COS DE BAHA N Niacinamide 10% Serum transforms one of K-Beauty's most versatile ingredients into a focused South Korean skincare ritual for visible clarity and balance. Powered by 10% niacinamide, this lightweight serum is designed to improve the appearance of enlarged pores and uneven skin tone while supporting a stronger-looking skin barrier. Its clear, watery texture absorbs quickly, creating an elegant treatment for those seeking Korean niacinamide skincare that feels concentrated yet effortless within a daily routine.

10% Niacinamide Meets 1% Zinc PCA

The defining partnership of 10% niacinamide and 1% Zinc PCA makes N Serum especially compelling for oily, combination and blemish-prone complexions. COS DE BAHA positions niacinamide for skin tone improvement, brightening, barrier support and sebum control, while Zinc PCA complements the formula's focus on excess oil and blemish-related concerns. Together, they help create the appearance of a clearer, smoother and more beautifully balanced complexion without relying on a heavy skincare texture.

A More Polished Look for Visible Pores & Uneven Tone

When pores, excess shine and uneven-looking texture interrupt the complexion's natural refinement, N Serum offers a targeted approach. The formula helps minimize the appearance of pores while addressing uneven tone and visible discoloration, allowing skin to appear increasingly harmonious. It is particularly suited to those searching for a Korean serum for pores, oily skin, dark spots and post-blemish unevenness, bringing several common complexion concerns together within one streamlined treatment.

Hydration Balances the Sebum-Focused Formula

Oil control need not mean stripping the complexion of moisture. Sodium hyaluronate, glycerin and betaine provide hydrating support, while aloe vera, allantoin and panthenol help condition the skin. Dipotassium glycyrrhizate adds another soothing element to the composition. This thoughtful supporting blend allows N Serum to pursue balance rather than dryness, leaving skin feeling comfortably hydrated while the niacinamide and Zinc PCA focus on tone, pores and sebum.

Botanical Care Within a Modern Korean Formula

Green tea, elderflower, bitter melon and edelweiss extracts complete the current formula with botanical skin-conditioning and antioxidant support. It is an approach that feels distinctly at home within modern K-Beauty: a meaningful concentration of a hero active surrounded by hydration and carefully selected supporting ingredients. The result is skincare that feels purposeful rather than excessive, designed to nurture the fresh, smooth and refined appearance associated with a beautifully maintained complexion.

A Weightless Daily Ritual, Morning or Evening

After cleansing and toning, apply an appropriate amount of the serum before moisturizer and gently pat until absorbed. COS DE BAHA's current guidance permits daily morning and evening use, while the clear, watery texture allows it to layer elegantly beneath subsequent skincare. During the day, complete the ritual with sunscreen—an essential finishing step when preserving an even, luminous-looking complexion is part of your beauty intention.

Where Balance Becomes the Secret to Korean Glass-Skin Clarity

Made in South Korea, COS DE BAHA N Niacinamide 10% Serum captures a quietly seductive truth about beautiful skin: luminosity is most captivating when the complexion also looks balanced. With 10% niacinamide, 1% Zinc PCA, hyaluronic hydration and soothing ingredients, each weightless application becomes an intimate ritual for pores, tone and clarity. Skin is invited to look smoother and fresher, with a refined radiance that feels polished without ever appearing overworked.
