I've seen good reviews for this product and thought to give it a try. Like most products, I tried it on the back of my hand in case I had any bad reactions and only found that it really worked in tightening the skin and it also made my skin look younger and revitalised? When I tried it on my face, it worked wonders in cleaning the oil from my face and minimising my blackheads. I'd recommend using it once a week as like all products, it will damage your skin if you use it too much.
