Only one problem
To create my paste, I mixed about 1/4 part water and 3/4 part baking soda (you can use what ever you please, it's preference). Then I washed my face until it was clean then I applied the paste with a brush, you can use your fingers though. The mask was a bit uncomfortable but that was because it was drying and tightening my skin, which I assumed would happen. After three uses of this, I saw INSANE results but the only bad thing is, after a week of using it everyday the results dumbed down and it stopped working. So I suggest that you use it and take a break for a week or so, other than that, it took away many acne scar! It's great before a big event! But make sure you test it on a small patch of skin first.
