The 6 Best Korean Niacinamide Serums for Brighter, Healthier-Looking Skin

June 25, 2026

Korean skincare has long been ahead of the curve when it comes to creating formulas that are both effective and remarkably gentle—and niacinamide is one ingredient that perfectly embodies that philosophy. Rather than relying on a single hero ingredient, many Korean serums pair niacinamide with barrier-supporting actives like Centella Asiatica, propolis, tranexamic acid, fermented extracts, and hyaluronic acid to target everything from excess oil and enlarged pores to pigmentation, redness, and dehydration.

It’s no surprise, then, that niacinamide has become a cornerstone of modern K-beauty. Suitable for nearly every skin type, it helps balance oil production, refine the look of pores, fade post-breakout marks, strengthen the skin barrier, and promote a brighter, healthier-looking complexion over time.

To help you find the right formula, we reviewed the best Korean niacinamide serums of 2026, evaluating each one for its ingredient blend, texture, skin-type compatibility, and overall performance. These are the six formulas that stood out.

The lightweight, refreshing ampoule absorbs quickly without leaving behind any stickiness, making it effortless to layer into both morning and evening routines.

Anua Peach 70 Niacin Serum

✦ Best for Glow

Ideal for: Dull skin, dehydrated skin, glass skin routines, everyday radiance

Glass skin isn’t just about brightness—it’s about skin that looks healthy, hydrated, and naturally luminous. That’s exactly where Anua’s Peach 70 Niacin Serum shines. Combining 5% niacinamide with peach-derived ingredients, triple hyaluronic acid, and barrier-supporting actives, it delivers a healthy-looking glow while helping skin feel soft, balanced, and comfortably hydrated.

The silky, lightweight texture absorbs quickly and layers effortlessly into both morning and evening routines without feeling sticky or heavy. While niacinamide and alpha-arbutin work over time to improve uneven skin tone, the immediate payoff is a fresh, dewy complexion that looks well-rested rather than overly glossy. Thanks to its gentle 5% niacinamide concentration and hydrating formula, it’s also one of the better options in this roundup for normal, dry, or slightly sensitive skin that doesn’t tolerate stronger treatments.

Why We Love It

• Creates a hydrated, luminous glow without feeling heavy
• 5% niacinamide offers gentle daily brightening
• Triple hyaluronic acid helps boost moisture levels instantly

JUMISO Niacinamide 20 Serum

✦ Best High-Strength Formula

Ideal for: Post-acne marks, hyperpigmentation, oily skin, experienced niacinamide users

For those who feel underwhelmed by lower-strength niacinamide serums, JUMISO offers one of the most potent options in K-beauty. With a substantial 20% concentration of niacinamide alongside tranexamic acid, glutathione, and hexylresorcinol, this serum is clearly designed for people looking to tackle persistent post-acne marks, uneven tone, and excess oil more aggressively.

Despite its strength, the formula feels surprisingly wearable. Centella-derived ingredients and multiple forms of hyaluronic acid help soften what could otherwise be an overly intense experience. The texture remains lightweight, absorbs quickly, and avoids the heavy or sticky finish often associated with highly concentrated treatments. While beginners may prefer something gentler, experienced users looking for a more corrective approach will likely appreciate the extra firepower.

Ideal for: Oily skin, enlarged pores, acne-prone skin, excess sebum

If controlling excess oil is just as important as fading post-breakout marks, COSRX The Niacinamide 15 Serum is one of the most targeted formulas in this roundup. It combines a potent 15% concentration of niacinamide with zinc PCA to help regulate excess sebum and N-acetyl glucosamine (NAG), an ingredient that works alongside niacinamide to improve uneven skin tone and post-acne discoloration.

Despite its higher strength, the lightweight gel-serum absorbs quickly and layers comfortably under moisturizer and sunscreen without leaving skin feeling tight or greasy. While it may be too active for very dry or sensitive skin, it’s an excellent choice for oily and acne-prone complexions looking to tackle excess shine, visible pores, and lingering acne marks with a single formula.

Why We Love It

• Specifically formulated for oily and acne-prone skin
• Combines niacinamide with zinc PCA and NAG for a multi-targeted approach

AXIS-Y’s bestselling Dark Spot Correcting Glow Serum is built around 5% niacinamide and a blend of hydrating and antioxidant-rich ingredients that focus on gradual, steady improvements in skin tone and radiance.

Numbuzin No.5 Vitamin Concentrated Serum

✦Best for Hyperpigmentation

Ideal for: Dark spots, post-acne marks, uneven skin tone, dull skin

Some brightening serums rely on a single hero ingredient, but Numbuzin takes a more comprehensive approach. Instead of putting all its weight behind niacinamide alone, this formula combines multiple brightening actives—including tranexamic acid, alpha-arbutin, glutathione, and several forms of vitamin C—to target stubborn discoloration from multiple angles. The result is a serum that feels more like an all-in-one radiance treatment than a traditional niacinamide serum.

Despite its impressive ingredient list, the formula remains surprisingly approachable. Panthenol, beta-glucan, ceramide NP, bifida ferment, and allantoin help cushion the skin, while the lightweight texture absorbs quickly without feeling greasy or heavy. It’s best suited to those looking to fade post-acne marks, uneven pigmentation, or lingering dullness over time. While consistent use is still key—as with any brightening serum—its well-balanced formula makes it one of the most complete options in this roundup.

Why We Love It

• Combines niacinamide with tranexamic acid, alpha-arbutin, glutathione, and multiple vitamin C derivatives
• Barrier-supporting ingredients help balance an active-rich formula
• Lightweight texture layers easily into both morning and evening routines

Frequently Asked Questions

What percentage of niacinamide is best?

For most people, 5% niacinamide is enough to improve skin tone, oil balance, and overall skin health. Stronger formulas containing 10% to 20% may be more effective for stubborn post-acne marks or excess oil, but they also have a greater chance of causing irritation. If you’re new to niacinamide, starting with a lower concentration is usually the best approach.

Can you use niacinamide every day?

Yes. Niacinamide is one of the most well-tolerated skincare ingredients and can be used once or twice daily by most skin types. If you’re using a higher-strength serum, such as 15% or 20%, it’s worth introducing it gradually before building up to daily use.

Can you use niacinamide with vitamin C?

Absolutely. The idea that niacinamide and vitamin C shouldn’t be used together is outdated. In fact, the two ingredients work well together and are often combined in modern formulas to help brighten skin, improve uneven tone, and provide antioxidant protection.

What is the best Korean niacinamide serum for sensitive skin?

SKIN1004 Madagascar Centella Tone Brightening Capsule Ampoule is our top pick for sensitive skin. It combines niacinamide with Centella Asiatica, tranexamic acid, and soothing barrier-supporting ingredients in a lightweight, fragrance-free formula that brightens skin while remaining gentle enough for daily use.
