JUMISO Niacinamide 20 Serum
Brightening Serum for Dark Spots, Acne Marks & Uneven Skin Tone
JUMISO Niacinamide 20 Serum is a powerful Korean brightening serum made to target dark spots, acne marks, hyperpigmentation, and uneven skin tone. It contains 20% niacinamide, along with tranexamic acid, glutathione, and centella, to help skin look clearer, smoother, and brighter.
If your skin looks dull or has stubborn post-acne marks, this serum is made for you. Additionally, it helps control excess oil and reduce visible pores. As a result, your skin looks more balanced and healthy with regular use.
Above all, the lightweight formula absorbs quickly without leaving a sticky finish. Therefore, it works well in both morning and night skincare routines. It is also fragrance-free and suitable for sensitive skin.
What Is Niacinamide?
Niacinamide is one of the most searched skincare ingredients for brightening and oil control. It is a form of vitamin B3 that helps improve skin tone and strengthen the skin barrier.
Additionally, niacinamide helps reduce the appearance of dark spots, enlarged pores, redness, and excess sebum. Because of these benefits, it is popular in Korean skincare routines for acne-prone and dull skin.
In JUMISO Niacinamide 20 Serum, a high 20% concentration is used for stronger brightening care.
Why Choose JUMISO Niacinamide 20 Serum?
Not all brightening serums work the same. Some only hydrate. Others only fade spots slowly. However, JUMISO combines multiple powerful ingredients in one formula.
This serum works on both surface discoloration and deeper pigmentation. Moreover, it helps calm redness while improving skin clarity.
Why users love it:
- 20% Niacinamide for brightening
- Tranexamic Acid for dark spots
- Glutathione for antioxidant care
- Triple Centella Complex for soothing
- Hyaluronic Acid for hydration
- Lightweight and fast absorbing
- Non-sticky finish
- Fragrance-free formula
Key Features
- Brightens dull skin
- Helps fade acne marks
- Reduces hyperpigmentation
- Improves uneven skin tone
- Controls excess oil
- Helps minimize visible pores
- Soothes irritated skin
- Supports skin barrier
- Safe for sensitive skin
Main Benefits
1. Dark Spot Care
This serum helps reduce the look of acne scars, sun spots, and post-inflammatory marks. Additionally, tranexamic acid and alpha brightening ingredients help improve stubborn pigmentation.
As a result, skin looks clearer over time.
2. Brighter Skin Tone
Dull skin can make the face look tired. However, this serum helps restore brightness and glow.
Niacinamide and glutathione work together to improve skin clarity. Therefore, skin looks more radiant and fresh.
3. Oil & Pore Control
Excess oil often makes pores look bigger. This formula helps balance oil production while keeping skin hydrated.
Because of that, skin feels fresh instead of greasy.
4. Soothing Care
Redness and irritation can make pigmentation worse. That is why JUMISO added Triple Centella Complex.
Additionally, centella helps calm stressed skin and support the skin barrier.
5. Barrier Support
A healthy barrier keeps moisture inside the skin. Hyaluronic acid and soothing ingredients help reduce dryness.
As a result, skin feels softer and more comfortable.
Texture and Finish
JUMISO Niacinamide 20 Serum has a lightweight watery-gel texture.
It spreads smoothly and absorbs quickly. Additionally, it feels comfortable on the skin without heaviness.
Texture benefits:
- Lightweight

- Layers well
- Makeup friendly
Therefore, it works well under sunscreen and makeup.
