Approximately 17 million people suffer from acne in the United States, reports the University of Virginia Health System. Caused by clogged skin pores and an infection of bacteria, acne can leave your skin looking inflamed and irritated. Several remedies, including both medical and natural cures, can help alleviate the signs of acne. Discuss your options with your doctor before treating your skin, as some acne medications and herbal remedies can have negative side effects.

Salicylic Acid

Salicylic acid is one of several chemicals recommended by the National Institutes of Health for over-the-counter acne treatments. The acid helps cure acne by boosting the cell turnover of dead skin, helping to slough off blockage and open up clogged pores.

Benzoyl Peroxide

Benzoyl peroxide is an effective active ingredient in numerous over-the-counter acne treatments, according to the University of Maryland Medical Center. Not only does it clear clogged pores, but the peroxide also kills the bacteria that causes acne.

Isotretinoin

Isotretinoin comes as a prescription oral medication from dermatologists and is one of the most effective medications for severe acne, according to the National Institute of Arthritis and Musculoskeletal and Skin Diseases. It's also often prescribed to help prevent the appearance of acne scars. The institute says you'll typically see a complete eradication of acne within 20 weeks.

Oral Antibiotics

Oral antibiotics work by reducing inflammation and killing the acne-causing bacteria. If given these pills, you must typically take them twice a day for a set period of weeks. Some of the most common oral antibiotics prescribed include minocyline, tetracyline and doxycycline, according to the National Institute of Arthritis and Musculoskeletal and Skin Diseases.

Tea Tree Oil

Tea tree oil, derived from the Melaleuca alternafolia tree, is a commonly used natural remedy for acne. In a concentrated strength of 5 percent, its natural antiseptic properties help kill the bacteria that cause acne and may be just as effective as non-natural medications like benzoyl peroxide, according to the University of Maryland Medical Center.

Guggul

The University of Maryland Medical Center reports that herbal guggul extract (Commiphora mukul), taken at a rate of 500mg twice daily, may perform like an oral antibiotic and may be as effective against acne as tetracycline pills.

Zinc

Zinc vitamins may improve the immune system and reduce the size and appearance of acne lesions, according to the University of Maryland Medical Center. The center advises taking 30 mg twice daily for 30 days, then just 30 mg a day for maintenance purposes.
