Antibiotics. These work by killing excess skin bacteria and reducing redness. For the first few months of treatment, you may use both a retinoid and an antibiotic, with the antibiotic applied in the morning and the retinoid in the evening. The antibiotics are often combined with benzoyl peroxide to reduce the likelihood of developing antibiotic resistance. Examples include clindamycin with benzoyl peroxide (Benzaclin, Duac, Acanya) and erythromycin with benzoyl peroxide (Benzamycin). Topical antibiotics alone aren't recommended.
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.
But the side effects of targeted breakout cream treatments aren’t always worth it. “So many products instruct consumers to use benzoyl peroxide spot treat red bumps and pustules. I don’t recommend it,” says Dr. Lawrence Green, board-certified dermatologist and assistant clinical professor of dermatology at George Washington University. Such high concentrations of benzoyl peroxide cause added irritation and inflammation to already sensitive skin, so with this in mind, we cut kits that included spot treatments.
Acne is caused by what you eat. SOMEWHAT FALSE. This isn’t a complete lie, but studies are still being done. To date, there have only been small studies done on a few people that have shown a possible connection between acne and high carbohydrate foods like bread, pastries and sodas. There are also studies involving more people, but they relied on adults remembering their acne and eating habits when they were in high school. There just isn’t enough evidence to link any food with breakouts. Some people swear that certain foods make their acne worse. The best way to determine if a food is causing your pimples to appear is by keeping a food/skin diary. Keep track of everything you eat and assess your skin condition in the morning and evening of each day. If you find a pattern, it can’t hurt to avoid the foods that lead to more blackheads and whiteheads. Keep in mind that eating a balanced diet is always a good idea.
Benzoyl peroxide attacks the P. acnes bacteria. However, one of its main side effects is dryness: If you’re going to use anything with benzoyl peroxide, make sure to moisturize afterwards. Sulfur and azelaic acid are less common and less severe alternatives to benzoyl peroxide. Dr. Peter Lio, assistant professor of clinical dermatology at Northwestern University, says sulfur-based treatments are “a good fit for patients who can’t tolerate the side effects of benzoyl peroxide.”
Acne medications work by reducing oil production, speeding up skin cell turnover, fighting bacterial infection or reducing inflammation — which helps prevent scarring. With most prescription acne drugs, you may not see results for four to eight weeks, and your skin may get worse before it gets better. It can take many months or years for your acne to clear up completely.
