Jumiso Niacinamide 20 Serum 40ml is a high-strength brightening serum formulated with 20% Niacinamide to help improve uneven skin tone, minimize the appearance of enlarged pores, regulate excess sebum, and visibly reduce the look of post-acne marks and dark spots. This lightweight Korean serum is designed to deliver intensive care while maintaining the skin’s moisture barrier, making it an excellent addition to a daily skincare routine for clearer, smoother, and healthier-looking skin.

Skin concerns such as acne marks, hyperpigmentation, dullness, and excessive oil production are common and can affect overall skin appearance. Jumiso Niacinamide 20 Serum is developed to target these issues with a concentrated dose of Niacinamide (Vitamin B3), one of the most researched skincare ingredients known for its ability to brighten the complexion, refine skin texture, and strengthen the skin barrier.

The lightweight, fast-absorbing formula spreads smoothly over the skin without leaving a sticky or greasy finish. It helps balance oil production while providing hydration, making it suitable for oily, combination, and acne-prone skin. With consistent use, the skin appears brighter, more even-toned, and smoother, while the appearance of enlarged pores and blemish marks is visibly reduced.

In addition to Niacinamide, the formula contains hydrating and soothing ingredients that help minimize the risk of dryness and irritation, allowing the skin to remain comfortable even with regular use. It layers easily under moisturizer and sunscreen during the day and works well as part of an evening skincare routine.
