Dapsone is a topical gel medicine sold under the brand name Aczone for treating severe acne, and it’s perfect for people who want a low-maintenance acne treatment plan. Unlike many of the best acne medications, dapsone only needs to be applied once daily, and it is the only medications most people will need, though it’s always good to include a face wash and moisturizer in your skin care routine if possible. Dapsone can function on its own because it is both antibacterial and anti-inflammatory10, effectively taking care of two of the biggest causes of acne.

Although home remedies are generally convenient and popular, some have significant counterproductive effects on the skin. The famous Procter & Gamble product Ivory Soap is probably the world’s most frequently used acne face wash ingredient. It is also probably the world’s worst acne face wash ingredient. Often advertised as “so pure that it floats,” Ivory Soap is depicted with pictures of babies and fair-skinned blondes to imply that it is a good and inexpensive face wash for acne-affected skin. Nothing could be farther from the truth.
Pharaohs are recorded as having had acne, which may be the earliest known reference to the disease. Since at least the reign of Cleopatra (69–30 BC), the application of sulfur to the skin has been recognized as a useful treatment for acne.[162] The sixth-century Greek physician Aëtius of Amida is credited with coining the term "ionthos" (ίονθωξ,) or "acnae", which is believed to have been a reference to facial skin lesions that occur during "the 'acme' of life" (puberty).[163]
Although combined oral contraceptives are a more popular treatment with women, men can use them as well, as they may also experience hormonal fluctuations. The only downside is that birth control pills tend to produce feminizing features in the person taking them, such as reduced hair growth or enlarged breast tissue. To get a prescription for a combined oral contraceptive, you can talk to your family doctor, a dermatologist, or an OB/GYN, or visit your local Planned Parenthood.
Any acne treatment is a weeks-long experiment that you’re conducting with your skin. Acne is slow to heal, and in some cases, it can get worse before it gets better (nearly every benzoyl peroxide product we looked at emphasized the likeliness of irritating acne further, and starting off with a lighter application). April W. Armstrong, a doctor at the University of California Davis Health System, recommends waiting at least one month before you deem a product ineffective.

Topical antibiotics deemed safe during pregnancy include clindamycin, erythromycin, and metronidazole (all category B), due to negligible systemic absorption.[46][137] Nadifloxacin and dapsone (category C) are other topical antibiotics that may be used to treat acne in pregnant women, but have received less study.[46][137] No adverse fetal events have been reported from the topical use of dapsone.[137] 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.[19] Oral antibiotics deemed safe for pregnancy (all category B) include azithromycin, cephalosporins, and penicillins.[137] 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.[1][137] Their use during pregnancy has been associated with development of acute fatty liver of pregnancy and is further avoided for this reason.[137]
The relationship between diet and acne is unclear, as there is no high-quality evidence that establishes any definitive link between them.[51] High-glycemic-load diets have been found to have different degrees of effect on acne severity.[7][52][53] Multiple randomized controlled trials and nonrandomized studies have found a lower-glycemic-load diet to be effective in reducing acne.[52] There is weak observational evidence suggesting that dairy milk consumption is positively associated with a higher frequency and severity of acne.[50][51][52][54][55] Milk contains whey protein and hormones such as bovine IGF-1 and precursors of dihydrotestosterone.[52] These components are hypothesized to promote the effects of insulin and IGF-1 and thereby increase the production of androgen hormones, sebum, and promote the formation of comedones.[52][56] Available evidence does not support a link between eating chocolate or salt and acne severity.[51][54] Chocolate does contain varying amounts of sugar, which can lead to a high glycemic load, and it can be made with or without milk. Few studies have examined the relationship between obesity and acne.[2] Vitamin B12 may trigger skin outbreaks similar to acne (acneiform eruptions), or worsen existing acne, when taken in doses exceeding the recommended daily intake.[57] Eating greasy foods does not increase acne nor make it worse.[58][59] One review linked a Western pattern diet, high in simple carbohydrates, milk and dairy products, and trans fats and saturated fats, along with a low omega-3 fatty acids, with acne.[56]

Genetics play a big part in who gets acne and how severely, but each blemish can be blamed on some combination of sebum production, a bacteria called Propionibacterium acnes (P. acnes), plugged follicles, and inflammation. Finding a good treatment is really about finding the right combination of ingredients to troubleshoot each of those issues. Some factors that might worsen acne include hormones, certain medications, diet and stress.

The dermatologist Dr. Dennis Gross did a major study on water and its effect on skin and he found that the heavy metals in tap water can actually ruin the benefits expensive lotions and serums do for skin. Some cities (New York and L.A., for example) have worse water than others (Seattle, for example). While some dermatologists aren't buying his claims, (Patricia Wexler for one), you can fight the drying effects of water on skin by cleansing with cold cream, a practice common with European women.
Retinoids and retinoid-like drugs. These come as creams, gels and lotions. Retinoid drugs are derived from vitamin A and include tretinoin (Avita, Retin-A, others), adapalene (Differin) and tazarotene (Tazorac, Avage). You apply this medication in the evening, beginning with three times a week, then daily as your skin becomes used to it. It works by preventing plugging of the hair follicles.
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]
