numbuzin No.5 Serum | Tranexamic Acid 4%, Niacinamide 5%, Glutathione, Vitamin C | Vitamin Concentrated Serum | Hyperpigmentation| Suitable for Sensitive Skin, Korean Skincare | 1.01 fl. oz.

Esto realmente me ayudó mucho más que otros productos que estuve utilizando, lo único malo fue que me salieron comedones pero eso lo solucionó con otro producto, por lo que realmente si me sentía mal era por las manchas tenía en la frente y del otro lado de la cara también pero solo tengo fotos de este lado

I love this item works great on the skin

One of my favorite skincare products. I use this night and day in conjunction with the Man:yo Bifida Biome serum and I’ve noticed a difference in skin texture, softness and evenness. I’ll definitely continue to use this product. (Over 50/combination skin)

I’m almost done with the bottle, so I wanted to leave a review. I’ve tried several products from Numbuzin, and while their popular toner didn’t work for me (unfortunately), I decided to give this serum a try despite my initial doubts—and I’m pretty satisfied with it!This serum contains glutathione and vitamin ingredients, which are known for their brightening and skin-tone-evening effects. While it’s not a dramatic change, after using it consistently, I’ve noticed that my complexion looks a bit brighter and more even. It’s not a miracle worker, but it definitely helps to improve skin tone over time.The texture is nice and smooth, but it does feel slightly sticky when first applied. Because of this, I usually wait a little while for it to fully absorb. Once it’s absorbed, the stickiness goes away, and my skin feels soft and moisturized. It’s not a dealbreaker for me, but it’s something to keep in mind if you're in a hurry.Pros:Noticeable brightening and evening of skin tone with consistent useContains glutathione and vitamin ingredients that are great for skinGood texture, leaves skin soft and moisturizedThe slight stickiness dissipates after absorptionCons:Slight stickiness that requires a bit of waiting for full absorptionNo dramatic changes, but subtle improvements with continued useOverall, I’m pleasantly surprised by the Numbuzin No.5+ Vitamin Concentrated Serum. It’s gentle on the skin, and with consistent use, I’ve seen a gradual improvement in my complexion. If you’re looking for a product with glutathione and vitamin ingredients, this is definitely worth trying!

Muy bonita te queda la piel se los recomiendo 👌

I love this serum. I use it in place of vitamin C. It also works well with other serums. It doesn't irritate my sensitive skin or make me break out. I'm on my third bottle and plan on purchasing for as long as I can. Highly recommend

Have only used a few times. Too soon for a complete review, but like how it soaks in, so far. No irritation noticed.

Not sure if I see a significant change. Feels nice but maybe need a very long time to see results.
