This is what works for acne. I thought I would share because I was paranoid that I was going to have acne scars mine was so bad.
First rub a dandruff shampoo or dawn dishwashing detergent on the effected areas. Rub it in thick. You should easily be able to see a layer of the solution on your skin.
A note on people who have it on their back. Mine is horrible on my shoulders. I can reach mine with my hands. If you have it on your back, you need to get a backscratcher and use a rubber band to put a wash sponge on it for application. I know this would work because I do it with a razor to shave my back.
Ok so now you have the dandruff shampoo whereever. You take a towel and drape it across your computer chair. You proceed to mess around on your computer posting on this site or whatever it is you do when you do your thing. Before bed take a shower to wash the stuff off. Technically, if you are going to wash your sheets in the next couple of days (and they are not dark colored), you can just rub the excess off with a towel and go to bed.
