Brightening Power Without the Drama: A Solid Niacinamide Serum That Works
The JUMISO Niacinamide 20 Serum is a genuinely good product that delivers noticeable results with consistent use. The formula feels lightweight and absorbs quickly, making it easy to incorporate into both morning and evening routines. Despite the high niacinamide concentration, it didn’t feel harsh or overly drying, and my skin looked more balanced and refined over time. The added glutathione and tranexamic acid give it an extra brightening boost, helping improve overall tone and clarity.What stands out most is how effective yet comfortable it is to use. My skin felt smoother, more even, and well-hydrated without irritation or pilling under moisturizer or makeup. A little goes a long way, and it layers well with other products, which makes it practical for everyday use. Overall, this serum feels thoughtfully formulated and reliable—an excellent option if you’re looking to target uneven tone and dullness with a product that quietly does its job well.

Great for dark spot and hyperpigmentation without irritation
20% niacinamide is way too much but surprisingly this one didn’t irritate my skin and it works really good! It clears my hyperpigmentation and dark spot within a month! I bought it twice already. It is now part of my skin care routine and one of my holy grail! Love it!

Its a nice niacinamide serum.
Truthfully I’m a little miffed. An influencer described this as a time release formula and I bought it without hesitation. yeah…boo. Lesson learned. Bc, there is nothing in the description saying that it is. I have no idea where she got that idea from…probably another influencer…you know how scientific these bobbleheads can be.But I got this on a Black Friday discount…so I couldn’t be too mad. I’m worried about potential irritation bc this is double the strength of the OG niacinamide serum from The Ordinary. So far it seems fine. There’s some additional ingredients in this serum…so maybe that will help keep irritation down. It’s a nice light formula with no stickiness. I don’t think the extra dye to make the serum appear plum color is necessary. Lots of ppl have allergies to dyes. For ppl with sensitive allergic skin…I’d be very careful around K beauty…and they often have long lists of plant based extracts that can trigger reactions. I can’t speak to the brightening effect of a 20% niacinamide strength over a 10%. But if you are looking for a bit of a change for your niacinamide, this product seems to be worth a look as the texture is very nice.

Great skin
A small amount goes a long way, very smooth and easy to use. Very moisturizing and absorbent blends well with my other products I use.
