I purchased this after going back and forth over a few brands. I have purchased an AHA, BHA peel from Dot & Key before and was very happy with it. I must say I got incredible results from the niacinamide serum as well. Very visible results from day 4 or 5. Would definitely recommend it.
The serums are reasonably priced for their amazing quality. My skin is prone to breakouts and I am on my 3rd bottle of the serums but they have been perfect for my skin!
