Core Product Details

10% Niacinamide for Pores, Oil & Uneven-Looking Tone

Jumiso Niacinamide 10% Serum is a concentrated Korean treatment created for the frustrating combination of dark spots, visible pores, excess sebum and uneven texture. At the center of the formula is 10% Niacinamide, supported by Tranexamic Acid, Glutathione, Succinic Acid and Zinc PCA. Rather than approaching brightness as a glow-only concern, Jumiso targets the factors that can make skin look less clear and refined—from lingering pigmentation and redness to excess shine and enlarged-looking pores.

Niacinamide 10% Takes Centre Stage

Niacinamide appears immediately after water in the official formula at a confirmed concentration of 10%. This multifunctional vitamin B3 derivative helps improve the appearance of uneven skin tone while supporting healthy barrier function and balancing the look of excess sebum. For combination, oily and blemish-prone complexions, that makes it especially useful when visible pores, shine and post-blemish discoloration tend to appear together rather than as isolated concerns.

Tranexamic Acid & Glutathione Strengthen the Brightening Strategy

Tranexamic Acid joins Niacinamide to provide more targeted support for the appearance of hyperpigmentation and uneven tone. Glutathione and Hexylresorcinol add further antioxidant and brightening support, creating a multi-ingredient approach to stubborn-looking discoloration. Jumiso's own clinical testing reports a 27.7% reduction in hyperpigmentation after two weeks under the specific study conditions, although individual cosmetic results will naturally vary.

Succinic Acid & Zinc PCA Focus on Pores and Sebum

What distinguishes this serum from many conventional Niacinamide treatments is its additional focus on oiliness and visible pores. Succinic Acid is incorporated to support smoother-looking texture and help reduce the appearance of enlarged pores, while Zinc PCA complements Niacinamide in the formula's sebum-balancing strategy. This makes the serum particularly relevant for skin that becomes shiny or congested while still needing treatment for discoloration.

Triple Centella Complex Helps Keep Skin Calm

Asiaticoside, Madecassic Acid and Asiatic Acid form Jumiso's Triple Centella Complex. These Centella-derived components provide soothing and barrier-supportive care to complement the serum's concentrated brightening formula. Allantoin and Portulaca Oleracea Extract add further conditioning support. Jumiso reports a 20% reduction in visible redness after two weeks in its clinical testing, reinforcing the formula's dual focus on clarity and comfort.

Three Hyaluronic Ingredients Add Lightweight Hydration

Hyaluronic Acid, Hydrolyzed Hyaluronic Acid and Sodium Hyaluronate join Glycerin and Squalane to help maintain moisture without turning the formula heavy or greasy. The serum retains a concentrated yet watery consistency that absorbs quickly and leaves little sticky residue, an important quality for oily and blemish-prone skin that still experiences dehydration.

Easy to Layer Morning or Night

After cleansing and toning, apply a moderate amount evenly across the face and gently pat until absorbed. Follow with moisturizer. Jumiso recommends the serum for both morning and evening use. When using it during the day, finish with broad-spectrum SPF 30 or higher; consistent sun protection is particularly important when your skincare goal is reducing the appearance of dark spots and maintaining a more even-looking complexion.

Clearer-Looking Skin Without Chasing a Perfect Pore

The beauty of this formula is that it does not treat radiance, pores and oil as completely separate conversations. One silky layer brings 10% Niacinamide together with TXA, Glutathione, Succinic Acid, Zinc PCA and soothing Centella actives, then disappears without a sticky finish. The goal is not impossibly poreless skin, but something far more compelling: a complexion that looks clearer, calmer, smoother and naturally more luminous.
