This is Good stuff. Plenty of acne treatments promise to fix the acne problem; however, scar zone DOES deliver on its promise. I started using this product to treat my acne scars and brown skin discoloration on my face and it worked. When I was using this product regularly, I did notice that my face was visibly brighter and more radiant looking. It does work but takes some time. Now since, returning to school and the stress, I have acne on my face again. So I returned to using this. so far it has been two weeks and do notice the brightness and clearing of my face, the acne is slowly going away, and hopefully will be gone in about three more weeks and then after that I will be using this product for maintenance treatments. That is something I did not do the first time. When using this product you have to have realistic expectation and patience. The tube is small, so it is not meant to be smeared over a very large area, (like back acne), if you do, you will go through the product quickly and It is on the costly side; also, a little does do a long way. Do not be heavy handed with this product, it does have some oils in it. You do not want to use too much and make the problem worst. You need just enough to lightly coat the area. Follow the instructions, it says to use twice a day. In the past, I have used it only once a day and seen results, but it will take longer that way. When I am treating a breakout, I use as recommended, but for maintenance, I will use it only once a day. Just know that this product takes time to work, but it does work. Immediacy You have to allow some time for this product to work.
