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

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.

It is fragrance-free, clear, and has a watery texture. In short, I feel like it is really helping with my skin texture, + healthy glow.

Muy buena calidad, súper recomendado

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!

Very happy this does not have a scent. I use it pretty often since I have acne scars that don’t seem to want to go away. After about a week, I started to see a difference in tone and my marks were starting to look lighter. I’m going to keep this up until they totally fade!

I love this stuff so much I received one free from the brand but I loved it so much I bought me a second one it’s fantastic it’s almost like a Serum it lasts so long and it works wonderfully

I bought it beacause of a recommend by a youtuber. So far, I haven’t feeled any effect. However, it is irritating to the skin. I spray it to my skin, sometines I can fell the irritation. So I guess it is not suitable for sensitive skin.

I use this at night as my first toner and I've noticed it brighten the dark spots that I have. I have combo skin (dry with oily T-zone) and this did not break me out. I use this in conjunction with a Vit C serum and I find that my skin tone is evening out a lot faster.

Best niacinamide I have ever used..it's been almost 2 years since I started using it and haven't experienced anything problem....

Muy hidratante

J'ai constaté un vrai coup d'éclat la première fois que j'ai utilisé ce produit dont le taux de concentration en niacinamide est supérieur à celui des autres produits disponibles en magasins cosmétiques. Si je l'utilise tous les jours, je remarque cependant que de petits boutons se forment sur ma peau, comme si mes pores étaient obstruées. J'espace donc mes applications d'une semaine environ, en effectuant des peelings et gommages légers entre deux sessions. Ma peau a alors l'air plus claire, et plus nette.

The best I have ever purchased.My skin is glowing and there is a visible reduction of my pigmentation in just 4 days..Note:-should use a very little quantity...(either dilute/take 1-2 drop to apply your whole face)

塗り始めは痒みと肌荒れが出ますが一週間程で落ち着きます気になる人は他の化粧水に混ぜて薄めて使うといいかもしれません保湿もしっかりできて美白効果もあるので使っていこうと思います
