Can't say its the best but it works very well and its good for many skin types 

It really works. The serum slightly exfolites without damaging or irritating your skin.

I wouldn’t say i have sensitive skin but this stings a lot when you apply it, very watery so it gets everywhere. It also has a strong smell. I purged when i first used it, it has helped with a bit with skin texture but it’s a bit of a hassle to use. 

If you are a beginner in acids it might be a very good solution!The serum doesn't hydrates my skin and its really good

I have seen so many people really liked the results of this product and now I understand reason why. It's really amazing and helps a lot with acne and pigmentation. Also specially with pores.
