Jumiso Niacinamide 20% Serum – 40ml | A High Strength for the Look of Spots
● About This Product
Jumiso Niacinamide Serum is a Korean serum in a 40ml size containing niacinamide (vitamin B3) at 20% — one of the highest strengths available in skincare. Niacinamide is among the most studied ingredients in skincare, and it is used to improve the look of dark spots and uneven tone, the look of pores and texture, and to support the skin barrier. The high strength means clearer results, but it also calls for a gradual introduction into your routine.

● What Makes It Different
Most niacinamide serums come at 5% or 10%. Those are good strengths, but they work slowly on stubborn spots. The 20% here is among the highest on the market and gives clearer results — on one condition, that you introduce it gradually: start once every two days in the evening, then build up, because a high strength can cause redness or a sting on sensitive skin at first. At 40ml for an economical price, it is strong value for a niacinamide serum.
