Postinflammatory hyperpigmentation (PIH) is usually the result of nodular acne lesions. These lesions often leave behind an inflamed darkened mark after the original acne lesion has resolved. This inflammation stimulates specialized pigment-producing skin cells (known as melanocytes) to produce more melanin pigment which leads to the skin's darkened appearance.[34] People with darker skin color are more frequently affected by this condition.[35] Pigmented scar is a common term used for PIH, but is misleading as it suggests the color change is permanent. Often, PIH can be prevented by avoiding any aggravation of the nodule, and can fade with time. However, untreated PIH can last for months, years, or even be permanent if deeper layers of skin are affected.[36] Even minimal skin exposure to the sun's ultraviolet rays can sustain hyperpigmentation.[34] Daily use of SPF 15 or higher sunscreen can minimize such a risk.[36]
Sodium sulfacetamide-sulfur is another acne medications often found in over-the-counter treatments, and it works especially well for those with mild-moderate acne that is largely made up of pimples. This is because it effectively dries out excess sebum without drying out the skin, and some studies suggest that this combination of sodium sulfacetamide and sulfur has antibacterial properties. According to one study published in The Journal of Clinical and Aesthetic Dermatology, sodium sulfacetamide 10 percent-sulfur 5 percent can significantly reduce the size of p. acnes colonies when used as an emollient foam6. This treatment option is also available as a facewash, topical gel, and topical cream, and can be found at most drugstores.
Acne vulgaris is the catch-all term for everything from angry red lesions to tiny white bumps, which are the results of hair follicles and their sebaceous glands becoming blocked and inflamed So our first plan was to look at it all — spot treatments, washes, scrubs and creams — until we learned that when it comes to over-the-counter treatments, there is no single cure.
Combined oral contraceptive pills contain progesterone and estrogen and help to balance out the levels of testosterone in the body12 One obvious effect of this is birth control, but dermatologists have also found it very useful for treating hormonal acne. Testosterone doesn’t directly cause acne, but when hormone levels fluctuate and testosterone increases above its baseline level, it can lead to increased acne for some. This is because increases in testosterone and other androgens leads to an increase in sebum production, which can cause more clogged pores and more p. acnes bacteria, leading to blackheads, whiteheads, pimples, or even cysts.
The idea behind using antibiotics for acne is that they can help reduce the number of p. acnes on the skin and relieve an acute case of severe acne. After the person stops taking the antibiotics, the hope is that the reduced numbers of p. acnes will prevent the pimples or cysts from getting out of hand again. However, in reality, most people simply end up taking the antibiotics much longer than they should, and the acne almost always comes back. That’s because, according to The Lancet: Infectious Diseases, over 50 percent of p. acnes strains are resistant to antibiotics7. If your doctor tries to prescribe you antibiotics for your acne, we recommend asking about other courses of action.

You’ve probably heard of the benefits of retinoid creams for anti-aging, but vitamin A is also efficient at clearing up acne. “[Retinoids] cause skin cells to turn over at a faster rate, decrease oil production, and help skin exfoliate,” board-certified dermatologist Rita Linkner, M.D., tells SELF. Another benefit: Acne is inflammation, and retinoids are anti-inflammatory.
The costs and social impact of acne are substantial. In the United States, acne vulgaris is responsible for more than 5 million doctor visits and costs over US$2.5 billion each year in direct costs.[13] Similarly, acne vulgaris is responsible for 3.5 million doctor visits each year in the United Kingdom.[19] Sales for the top ten leading acne treatment brands in the US in 2015, have been reported as amounting to $352 million.[175]
Acne treatment that you apply to the skin: Most acne treatments are applied to the skin. Your dermatologist may call this topical treatment. There are many topical acne treatments. Some topicals help kill the bacteria. Others work on reducing the oil. The topical medicine may contain a retinoid, prescription-strength benzoyl peroxide, antibiotic, or even salicylic acid. Your dermatologist will determine what you need.
