For some, the right dosage can be found over-the-counter in concentrations as low as 2.5 percent or up to 10 percent, but for others, a prescription dosage is needed to see the best results. Prescription doses rarely go over 10 percent, as benzoyl peroxide is known to cause stinging, burning, itching, flaking, peeling, and redness2 when used in concentrations over 5 percent, but they may combine the benzoyl peroxide with other acne medications.
Alternative and integrative medicine approaches used in the treatment of acne include fish oil, brewer's yeast, probiotics, oral zinc and topical tea tree oil. More research is needed to establish the potential effectiveness and long-term safety of these and other integrative approaches, such as biofeedback and traditional Chinese medicine. Talk with your doctor about the pros and cons of specific treatments before you try them.
A complete skin care regimen to control acne usually starts with washing. The ideal face wash creates a soft creamy lather in warm water. It rinses off dirt, excess oil, and makeup, leaving the face ready for the next step in daily skin care, whether that is toner, moisturizer, exfoliant, sunblock, or more makeup. It is fragrance-free, and it does not create a foam, film, or tingly sensation on the face. Any product that foams and suds vigorously, like a detergent, is a strict no-no for acne treatment, especially on dry skin.
Spironolactone has relatively minor side effects, like low appetite, weakness, or cramping, but there’s one major exception: spironolactone comes with a black box warning about its cancer-causing effects. The FDA is required to include this label based on a study conducted in the 1950s that found carcinogenic properties in the spironolactone given to rats in an experiment. However, the dose of spironolactone used in this study was nearly 500 times higher than the dose currently prescribed, and no studies since have found anything carcinogenic about spironolactone. Because of this, most dermatologists feel comfortable prescribing spironolactone for acne. Still, it’s something to be aware of before you take it. Additionally, those with low blood pressure or kidney conditions are likely not good candidates for spironolactone and may want to explore other acne treatment options.
According to a 2016 review of research that examined how diet may impact breakouts, researchers concluded that “compelling evidence shows that high glycemic load diets may exacerbate acne.” Foods high on the glycemic index (GI) tend to be higher in refined carbs, like those found in white bread. Scientists suspect that raised insulin levels from the carbs may trigger a release of hormones that inflame follicles and increase oil production.
If you’re used to seeing advertisements for acne treatments using five or six different products to clear up blemishes, you might be surprised that a simple three-step kit is our top pick. In fact, we favored Paula’s Choice for its simplicity. This twice-daily, three-step kit — which includes a cleanser, an anti-redness exfoliant, and a leave-on treatment — is concise without cutting corners.
Aside from adding bacteria to your skin, these forms of contact can irritate the skin, adding to the appearance of redness and causing increased inflammation. In the event that your pimples get ruptured during this process, the oil and bacteria that was trapped inside could spread to the surrounding skin on your face, which causes acne to spread. So, not only will rubbing, squeezing and scratching leave your acne-ridden skin further irritated, it will increase the amount of acne you will have to deal with.
Topical antibiotics deemed safe during pregnancy include clindamycin, erythromycin, and metronidazole (all category B), due to negligible systemic absorption. Nadifloxacin and dapsone (category C) are other topical antibiotics that may be used to treat acne in pregnant women, but have received less study. No adverse fetal events have been reported from the topical use of dapsone. If retinoids are used there is a high risk of abnormalities occurring in the developing fetus; women of childbearing age are therefore required to use effective birth control if retinoids are used to treat acne. Oral antibiotics deemed safe for pregnancy (all category B) include azithromycin, cephalosporins, and penicillins. Tetracyclines (category D) are contraindicated during pregnancy as they are known to deposit in developing fetal teeth, resulting in yellow discoloration and thinned tooth enamel. Their use during pregnancy has been associated with development of acute fatty liver of pregnancy and is further avoided for this reason.
What it does: Benzoyl peroxide is the only known substance which can bring oxygen under the skin surface. Since bacteria cannot survive in the presence of oxygen, when used in an adequate dosage, benzoyl peroxide eradicates 99.9% of these bacteria almost immediately. It also exerts a mild drying and peeling effect, which is thought to help prevent breakouts.1-6 Benzoyl peroxide also helps lessen inflammation.7-9 2.5% benzoyl peroxide is just as effective as higher concentrations with less side effects.6,10
Scars (permanent): People who get acne cysts and nodules often see scars when the acne clears. You can prevent these scars. Be sure to see a dermatologist for treatment if you get acne early — between 8 and 12 years old. If someone in your family had acne cysts and nodules, you also should see a dermatologist if you get acne. Treating acne before cysts and nodules appear can prevent scars.
