Acne vulgaris and its resultant scars have been associated with significant social and academic difficulties that can last into adulthood, including difficulties obtaining employment.[31][177] Until the 1930s, it was largely seen as a trivial problem among middle-class girls – a trivial problem, because, unlike smallpox and tuberculosis, no one died from it, and a feminine problem, because boys were much less likely to seek medical assistance for it.[165] During the Great Depression, dermatologists discovered that young men with acne had difficulty obtaining jobs, and during World War II, some soldiers in tropical climates developed such severe and widespread tropical acne on their bodies that they were declared medically unfit for duty.[165]

Combination therapy—using medications of different classes together, each with a different mechanism of action—has been demonstrated to be a more efficacious approach to acne treatment than monotherapy.[10][47] The use of topical benzoyl peroxide and antibiotics together has been shown to be more effective than antibiotics alone.[10] Similarly, using a topical retinoid with an antibiotic clears acne lesions faster than the use of antibiotics alone.[10] Frequently used combinations include the following: antibiotic and benzoyl peroxide, antibiotic and topical retinoid, or topical retinoid and benzoyl peroxide.[47] The pairing of benzoyl peroxide with a retinoid is preferred over the combination of a topical antibiotic with a retinoid since both regimens are effective but benzoyl peroxide does not lead to antibiotic resistance.[10]
Shah often recommends over-the-counter retinols or prescription retinoids to her acne-prone patients. “I find that compared to other treatments they are beneficial for not just treating acne but also preventing new acne from forming as they help prevent that initial stage of the follicle getting clogged,” she says. “They can also help with some of the post acne [problems] such as hyperpigmentation.” But keep in mind if you have sensitive skin (or eczema or rosacea), a prescription retinoid might be too strong an option. However, your dermatologist can recommend an over-the-counter retinol with a low concentration (0.1 to 0.25 percent), which might be better tolerated. Retinol also isn’t a quick fix. It takes time to see results, and it’s something you’ll have to keep using to maintain its benefits. Shah also mentions that retinol plays well with other acne treatments on the list. "Retinol can be combined with other over-the-counter or prescription medications such as benzoyl peroxide, topical antibiotics, and oral medications. The right combination depends on the severity of the acne and your skin type."
Spironolactone is an androgen blocker. It can be used to treat hormonal acne in women (only) by reducing the production of androgens (male hormones) in a woman's body, which can then reduce oil production in the skin. If you're wondering how to get rid of acne overnight, keep in mind that aldactone can take up to three months to start taking effect.

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.
