Considerations: Side effects are generally mild and short lived. Most common, in 1-5% of people are itching, burning, stinging, and tingling. Other side effects were reported in less than 1% of people. There have been a few reports from darker skinned people of lightening of the skin. Azelaic acid has not been well studied in people with dark complexions.1
Even though scientists know how pimples and blackheads are formed, they are still not sure what causes you to have a body full of blemishes and the guy sitting next to you not to have a single spot on his face? It’s probably related to hereditary factors. If your parents dealt with acne when they were younger, you’re more likely to struggle with acne, too.
Considerations: Ask your doctor before using any other products on your skin while using erythromycin, as it may be too irritating. This includes other prescriptions, over-the-counter medicines (including those listed on this site), and harsh or abrasive cleansers, perfumes, or make-up.2 People report burning as the most frequent side effect, and also peeling, dryness, itching, redness, and oiliness, among others.2
Retinoids: Retinoids are substances that are derived from vitamin A, which includes retinol, but also includes synthetic versions of retinol with activated retinoic acid which tends to be more effective in treating acne. Retinoic acid has been shown to reduce sebum production8 and regulate skin cell production9, which together can greatly reduce acne. These synthetic retinoids include adapalene, tretinoin, isotretinoin, and others. Although these synthetic options are more reliably effective, they also tend to have more side effects, like burning, itching, and dryness. Unlike retinol, which is available over-the-counter, nearly all synthetic retinoids are prescription-only. One of the main exceptions is Differin, which is a brand that sells a topical gel containing adapalene, a mild synthetic retinoid, over-the-counter.
Antiandrogens such as cyproterone acetate and spironolactone have been used successfully to treat acne, especially in women with signs of excessive androgen production such as increased hairiness or skin production of sebum, or baldness. Spironolactone is an effective treatment for acne in adult women, but unlike combined birth control pills, is not approved by the United States Food and Drug Administration for this purpose. The medication is primarily used as an aldosterone antagonist and is thought to be a useful acne treatment due to its ability to additionally block the androgen receptor at higher doses. Alone or in combination with a birth control pill, spironolactone has shown a 33 to 85% reduction in acne lesions in women. The effectiveness of spironolactone for acne appears to be dose-dependent. High-dose cyproterone acetate alone has been found to decrease symptoms of acne in women by 75 to 90% within 3 months. It is usually combined with an estrogen to avoid menstrual irregularities and estrogen deficiency. The medication has also been found to be effective in the treatment of acne in males, with one study finding that a high dosage reduced inflammatory acne lesions by 73%. However, the side effects of cyproterone acetate in males, such as gynecomastia, sexual dysfunction, and decreased bone mineral density, make its use for acne in this sex impractical in most cases. Hormonal therapies should not be used to treat acne during pregnancy or lactation as they have been associated with birth disorders such as hypospadias, and feminization of the male babies. In addition, women who are sexually active and who can or may become pregnant should use an effective method of contraception to prevent pregnancy while taking an antiandrogen. Antiandrogens are often combined with birth control pills for this reason, which can result in additive efficacy.
