Rates appear to be lower in rural societies. While some research has found it affects people of all ethnic groups, acne may not occur in the non-Westernized peoples of Papua New Guinea and Paraguay.
Use AHAs and BHAs. Alpha Hydroxy Acids are essentially exfoliants, sloughing off dead skin that tends to clog pores and cause acne. Beta Hydroxy Acids fight the acne bacteria from the inside out. If you can, try to find a body scrub with AHAs and wash with that scrub three times per week. After showering and moisturizing, wipe your back with BHA-medicated pads.
If your acne scars are not severe, you can probably ask for a lighter peel. There are many affordable home kits available out there that are very effective like this one. You will probably find every strenth you need depending on your skin condition.
Bactrim contains trimethoprim and sulfamethoxazole, which both treat different types of bacterial infections. Avoid this medication if you have an allergy to any of its contents. The side effects of Bactrim include joint pain, insomnia, ringing in the ears, swollen tongue and dizziness.
It’s best to consult a primary-care physician or dermatologist if an individual is unable to adequately control his or her acne. The goal of treatment should be the prevention of scarring (not a flawless complexion) so that after the condition spontaneously resolves there is no lasting sign of the affliction. Here are some of the options available:
What it is: Spironolactone is a prescription medication in tablet form used to treat certain patients with hyperaldosteronism (the body produces too much aldosterone, a naturally occurring hormone), low potassium levels, and in patients with edema (fluid retention) caused by various conditions.1Learn more from the U.S. National Library of Medicine.
Oral antibiotic use can lead to vaginal candidiasis; doxycycline can be associated with photosensitivity; and minocycline has been linked to pigment deposition of the skin, mucous membranes, and teeth. 
Even if you get acne, you don’t want to make it worse. That’s why it’s important to keep your hands off your pimples. Try not to touch, squeeze, or pick at a pimple. When you play around with pimples, you can cause even more inflammation by poking at them or opening them up. Plus, the oil from your hands can’t help! The worst part, though, is that picking at pimples may lead to scars on your face.

There is also a growing body of evidence for laser treatment of acne, standalone or in the context of PDT. However, similar to light therapy, the power and quality of research is limited by small patient numbers, lack of a control population, and comparison to standard therapies. Nonetheless, preliminary studies have shown improvement in acne, and even potential long-lasting effects with the 1550-nm erbium-glass laser, 1064-nm Nd:YAG laser, and PDT with laser. 
For acne-prone skin during breakouts, it’s important to protect against sun exposure. Ultraviolet rays stimulate pigment producing cells, increasing the risk of acne scarring. (13) The best option is to use natural sunscreens and to only get an appropriate amount of direct sun exposure daily (about 15-20 minutes most days). Commercial sunscreens are packed with harmful chemicals that can irritate sensitive skin and acne-prone skin. Research shows that coconut oil has an SPF value of 8, as does olive oil. (14) To use as sun protection, apply a moderate amount to exposed skin every couple of hours and try to avoid spending too much time in direct sunlight during “peak” hours, which is about from 10am-3pm each day.
Anyone who has severe acne knows how stubborn it can be. You cannot clear it with acne treatment that you buy at the store. To see clearing, you either have to wait it out or see a dermatologist. Waiting out severe acne can take years.
