Ok, well I used baking soda for my acne, and it was the best spend dollar I have ever spent! I would use it once a day(at night) and immediatly saw dramatic results. In about five days all of my acne was gone. I was really happy with the results. But ...the baking soda burned my skin. By "burned" I mean discoloration, peeling, and acne scars. Dark acne scars, that are very noticable. But if you have products to treat that already(unlike me, I was so unprepared) go ahead and give it a shot. Its the most effective cure for acne out there! It kills the bacteria, leaving your skin acne free! The peeling, by the way, went away after two long weeks. The acne scars, are still there. So is the discoloration. But still better than suffering with acne. I'm going to buy something to help the scars and discoloration, I will tell you if it works. At a dollar a box, this is the best solution to your acne problems. I would leave it on for 5 minutes before washing it off, you guys should learn from my mistake and leave it on for only 2 to reduce damage.
