For women who break out mainly around their menstrual cycle, some birth control pills can help. Research shows that these pills can clear acne by slowing down overactive oil glands in the skin. Sometimes, birth control pills are used along with a drug called spironolactone to treat acne in adult females. This medication lowers levels of the hormone androgen in the body. Androgen stimulates the skin's oil glands. Side effects of this drug include irregular menstruation, breast tenderness, headache and fatigue. Spironolactone is not appropriate therapy for all patients.
You can help keep rosacea under control by keeping a record of things that cause it to flare up. Try to avoid or limit these triggers as much as you can. Antibiotic lotions or gels can also help. Sometimes, you may need to take antibiotic pills. Your dermatologist may treat you with laser surgery. If you think you have rosacea, talk with your doctor about these treatments.

Lasers. Your dermatologist can use a laser to remove the outer layer of your skin, contour areas of acne scars, or lighten redness around healed acne lesions. Various types of lasers are used, depending on whether the acne scar is raised or flat. More than one laser treatment may be required and, depending on the laser used, you may need to several days to heal.

Topical (external) applications: Antibacterial cleansers come in the form of gels, creams, and lotions that are applied to the affected area. The active ingredients that kill surface bacteria include benzoyl peroxide, sulfur, and resorcinol. Some brands promoted on the Internet and cable TV (such as ProActiv) are much more costly than identical and sometimes more potent products one can buy in the drugstore.

You can apply all the topicals you want, but unfortunately, most treatments you'll find at the drugstore won't help with acne scars, Hellman says. However, she notes that derma rollers (at-home microneedling devices) may help with acne scarring. If you're on a tight budget, that should be your first stop. You can get one on Amazon for less than $20. (Use yours once a week followed by a Vitamin C serum for best results—here's how to pick the best ones.)
While acne is a much more visible condition than most, it is important to remember that it is like most diseases, in which early detection can help to mitigate its impact. Bearing that in mind, we have taken the time to put together 10 of the most common causes for acne, so that you can be better informed and potentially avoid some (and only some) of its root causes.
Take a small fresh lemon and squeeze out its content juice. Apply the juice directly on the scars using the finger tips or a clean cotton ball, leave it for about 10 minutes and wash it off using cold water. Do this at least once a day for about two to three weeks during after which you can see the scars disappear considerably. If you want, you can also mix some honey with the lemon juice to make it some more effective in reducing of the acne scars.
A recent study has found a difference between strains of acne bacteria, which could have a significant impact on acne treatment down the road. This study, published in the Journal of Investigative Dermatology, found that these strains play a role in the severity and frequency of developing pimples. One particular strain of P. acnes was found among study participants that exhibited few symptoms of acne. Researchers came to the conclusion that this “good” strain of bacteria features a natural defense mechanism that fights back bacteria which might infect the cell. Researchers are hopeful that this discovery will help dermatologists better and more accurately prescribe effective acne treatment in the future, and reduce the severity of acne by ridding the skin of bad acne bacteria while preserving the good. 
Acne remedies benzoyl peroxide and salicylic acid are key ingredients in body washes designed to get rid of acne. Choose an oil-free body wash with acne medication like benzoyl peroxide or 2 percent salicylic acid. Apply the body wash to the affected areas and leave on for a minute or two to allow the acne medication to work its magic. Rinse well. Remember that products that contain benzoyl peroxide bleach fabric and may ruin towels, clothes and sheets/pillow cases. Change to white or something you don't mind bleaching.

Moderation and regularity are good things, but not everyone can sleep eight hours, eat three healthy meals per day, and drink plenty of water a day. Probably the most useful lifestyle changes one can make is to never to pick or squeeze pimples. Playing with or popping pimples, no matter how careful and clean one is, nearly always makes bumps stay redder and bumpier longer. People often refer to redness as "scarring," but fortunately, it usually isn't permanent. It's just a mark that takes months to fade if left entirely alone.
