How can you tell if your Jumiso Niacinamide 20 Serum is original?
- The serum should be smooth and light, absorb within a minute and have little or no smell; a separated, gritty or perfumed liquid is a warning sign.
- The box should be sealed, with the Jumiso name, Niacinamide 20 and the ingredient list printed clearly; blurred printing or spelling mistakes suggest a copy.
- A price far below other trusted sellers usually means old stock or a fake.
- Check the batch code printed on the box and the bottle: the two must match, and the code should look printed, not stuck on. Every unit we sell is batch-code checked on arrival in Seoul, and we verify any code for free — see how to check if Korean skincare is original.

Jumiso Niacinamide 20 Serum: frequently asked questions

Our stock is bought from official Jumiso channels in Seoul, every unit is batch-code checked on arrival and shipped from our Seoul warehouse.

Is 20% niacinamide too strong?
It is a high strength, so it suits skin that already tolerates niacinamide. Some people notice short-lived redness or tingling at first. Start once a day and build up. If your skin is sensitive or new to niacinamide, a 5–10% serum is a better first step; higher strength is not always better.
Does Jumiso Niacinamide 20 help dark spots?
It helps dark spots and post-acne marks look lighter and more even with steady daily use, which is why many people buy it as a dark spot serum. Expect gradual change over a couple of months. Sunscreen every morning is essential, because sun exposure darkens marks again.
Can I use it with vitamin C, retinol or BHA?
Yes. Niacinamide combines well with most actives. Use vitamin C in the morning and this serum after it or in the evening, and pair it with retinol or BHA at night once your skin is used to each one. Add one new active at a time.
How long does it take to see results?
Shine and the look of pores can change within a few weeks. Dark spots and post-acne marks usually take a couple of months of daily use, and deeper marks take longer. Keep using sunscreen and avoid picking at spots, which creates new marks.
