I have used it twice and I feel my skin cleaner. The first time with a small amount, I didn't feel anything, the second time with more, I had tickles. I have also tried the ORDINARY aha bha and it was stronger and more irritating but my skin was glowing more and slightly smoother.
*I will update in two months of use again

It is a very powerful and professional product. Once a week is enough. We stop using it during the summer because of the sun. It may sting a little and the skin may turn red (this is normal), but in the end, you achieve a refreshed and radiant complexion. No need to visit beauty centers. A high-quality and effective product at an affordable price. It is necessary to use a moisturizing mask afterwards.
