Being rid of acne can be difficult for some people. What works for one person may not work for another. A medical doctor can prescribe a tablet and a topical medication. Be sure you ask about the side effects of the prescription tablet (as some people have had problems). Then some have no problems. This helps some people quickly and takes more time for others. Each person is different. And more than one prescription may be needed.
There are also 'home remedies.' There have been some hubs written about natural or herbal remedies. If you like type in 'natural remedies' or 'herbal treatments' in the hubs category and see what comes up.
