If you have acne on your back, there could be a couple of plausible reasons for this. One would be that you have oily skin, which has led to oily deposits sitting on your back. This is generally the most popular cause of acne anywhere on the body. The back, especially, gets neglected in the cleaning process completely, since we can barely reach it. For people with oily skin, extra care should be taken to clean the back. The problem is also aggravated because the back is covered for most part. This leads to perspiration, which also help along the process of blocking your pores considerably. One of the first things to check and take care of is that you stop wearing polyester clothing. This will tend to trap sweat, dirt and heat between the clothes and your body and will lead to clogged skin. Cotton clothing, on the other hand, will allow your body to breathe better and will prevent this problem.
You must also make it a point to start cleaning your back properly. While this is a tough task, it is hardly impossible to accomplish. Buy a long loofah, which is commonly available everywhere and start using it to scrub your back. If you can, enlist the help of another person to scrub your back well about thrice a week for two weeks, and then once a week afterwards. This will help considerably. You can buy any exfoliating scrub over the counter for this purpose. You can also make your own by mixing enough sugar crystals and olive oil to get a paste-like consistency and use this. Add a few drops of lime juice to this for instant sanitization of the skin as well. Switch to using sandalwood based soap, and make it a point to powder your back as well, as this will absorb extra sweat.
