Has anyone used Alum for Acne treatment?

Re: Has anyone used Alum for Acne treatment?

Its to control acne and then clear the acne scars. Its topical. All I do is wash my face and then wed the Alum (in rock form) and rub it a little on the face where acne is. Best done before going to sleep but that’s not practical for me so I apply it just before leaving for the office. Significant improvement so far. There might be other process to apply alum as well but didn’t try any. There are visible results in a week or so.
