Don't even know how many bottles did I use. And it's working great every time on my super oily skin. Might be a bit sticky if I apply too much but for it's price it is the best niacinamide I've ever had

good product to try with good result

I put this on every single morning, and I love it. I can't say that I see some major difference, but what it does for your skin isn't just seen. It's a long-term good thing that brightens and keeps your face healthy.

Best best best.

Si vous avez une peau Grasse à tendance acnéïque, regardez dans cette direction!!!!! Il est excellent, De texture légère il rend la peau tout doux. Je ne peux plus m'en passer

I I love all the product from Stylekorean. They provide only the authentic products to customers. I can say Stylekorean is the most trustful website for everyone who is interested in Korean cosmetics.

I discovered this from k beauty YouTube influencers that talk this serum up quite a bit. (James Welsh/Kelly Driscoll) everything they said about it was true. It really is fading my powt acne marks, I love it! I will be repurchasing!

Absolutely love this buying it again!!!!
