I was astonished after checking the ingredients list that this product has safe and beneficial ingredients!
Just did not expect it from the peeling type of the product.
Now I see why CNP booster has so many funs.
I had a lot of samples home, but were afraid to use acids before, but now I started to make a 10-days course and I see the "touchable" difference without any bad feeling on my skin.
I am sure this is not a product for daily use, but when you make several courses during the year, this should be definitely safe for the skin!
