ONE THING Niacinamide 10% Toner 5.07 Fl Oz | Vitamin B3 Hydrating Revitalizing Soothing Facial Daily Essence Dull, Oily Skin | Discoloration, Redness, Acne Scars Relief, Uneven Tone | Korean Skin Care

ONE THING says it all. Its a must have. I have repeatedly ordered the niacinamide oho I don’t know how many times now, and I absolutely love what it does for my face. I went from dull to smooth and soft glass skin in such a short time. It definitely got rid of any roughness and being in my 50’s with aging pores it helps keep them from being too big. Definitely a must have

As a dark-skinned woman who doesn't put many things on my face, I love this stuff. I definitely do not look my age!

Liked it! The product i was looking for and perfect for my skin type.

This is the second time I've bought this. The first time I found it at a baby store in Skopje, North Macedonia. The store had an entire wall of Korean skincare. I knew Niacinamide helped with uneven skin tone and just as the bottle describes -- it's literally only niacinamide. Most ferns recommend 8% or less but my skin holds up well to strong products (and I prefer it). This is great for people who like to layer skincare with specific targeted products. I will use this right after cleansing, followed by vitamin C, retinol and a hyperpigmentation serum. I know this works because I'm fading a scar on my nose and although it's not immediate I have noticed fading in the long term. This is a well known brand.

Es muy bueno para controlar el frizz del cabello

I'm just giving it 4 stars because I haven't use the product enough. I've just used this toner like two times now so...can't really say much. It arrived on time and everything was sealed, the box the bottle, everything. It does not smell at all, and I think it's actually a good thing because I am very sensitive to smells and also have sensitive skin. I will update this review later on when I have used the product long enough to update you guys!

Excellent

I gave 5 stars because of the beautiful simple package which matches the simple ingredients. But I’m one of the unfortunate individual who can’t tolerate high percentages of niacinamide. Within 2 days of using it morning and evening, my skin started to peel and became itchy with red bumps. My skin didn’t react to the 2 % niacinamide, but perhaps the 10% is just way too strong for my sensitive skin. I’m also using tretinoin 0.5% cream as well with sensitive combo acne prone skin. I would say if you have sensitive skin that’s acne prone, you may want to be careful with this product. I still give a 5 star review because i still think the is a great product & lots of people can benefit from adding niacinamide to their skincare regimen, but it’s just not for my skin type.
