I use it to exfoliate every other day, and I use it as a mask twice a week.
I have oily, acne-prone skin and I live in the tropics. I have always had issues with acne, but four years ago it became severe. It was so bad I started using accutane which worked, but I was never comfortable with the side effects.
Last year I started to develop cystic acne once again and I decided that I was tired of using pills and brand name acne products that never seemed to work long enough. I did some research and heard about the use of baking soda. I tried other things as well, but this was the one thing that continued to work
Now I hardly break out. It has cleared up my acne, and my dark spots are on their way out the door!
It takes time, and patience is required, but if you stay consistent you will see the results.
