Genetics is thought to be the primary cause of acne in 80% of cases.[2] The role of diet and cigarette smoking is unclear, and neither cleanliness nor exposure to sunlight appear to play a part.[2][13][14] In both sexes, hormones called androgens appear to be part of the underlying mechanism, by causing increased production of sebum.[5] Another frequent factor is excessive growth of the bacterium Cutibacterium acnes, which is normally present on the skin.[15]
How to Handle It: Your best bet is benzoyl peroxide. "Benzoyl peroxide can kill acne-causing bacteria and reduce inflammation," says Zeichner. Try a cream like the La Roche-Posay Effaclar Duo Dual-Action Acne Treatment ($37), which also exfoliates with lipo-hydroxy acid. Be aware that it can seriously dry out skin so moisturize well after you use it.

Side effects include increased skin photosensitivity, dryness, redness and occasional peeling.[81] Sunscreen use is often advised during treatment, to prevent sunburn. Lower concentrations of benzoyl peroxide are just as effective as higher concentrations in treating acne but are associated with fewer side effects.[80][82] Unlike antibiotics, benzoyl peroxide does not appear to generate bacterial antibiotic resistance.[81]

Isotretinoin is an oral retinoid that is very effective for severe nodular acne, and moderate acne that is stubborn to other treatments.[1][20] One to two months use is typically adequate to see improvement. Acne often resolves completely or is much milder after a 4–6 month course of oral isotretinoin.[1] After a single course, about 80% of people report an improvement, with more than 50% reporting complete remission.[20] About 20% of patients require a second course.[20] Concerns have emerged that isotretinoin use is linked with an increased risk of adverse effects, like depression, suicidality, anemia, although there is no clear evidence to support some of these claims.[1][20] Isotretinoin is superior to antibiotics or placebo in reducing acne lesions.[17] The frequency of adverse events was about twice as high with isotretinoin, although these were mostly dryness-related events.[17] No increased risk of suicide or depression was conclusively found.[17] Isotretinoin use in women of childbearing age is regulated due to its known harmful effects in pregnancy.[20] For such a woman to be considered a candidate for isotretinoin, she must have a confirmed negative pregnancy test and use an effective form of birth control.[20] In 2008, the United States started the iPLEDGE program to prevent isotretinoin use during pregnancy.[85] iPledge requires the woman under consideration for isotretinoin therapy to have two negative pregnancy tests and mandates the use of two types of birth control for at least one month before therapy begins and one month after therapy is complete.[85] The effectiveness of the iPledge program has been questioned due to continued instances of contraception nonadherence.[85][86]
3. Self-Care: Self-care practices and lifestyle choices can also help clear complexions. Nutrition, stress management, ample sleep, and good hygiene can help treat existing acne and might be able to prevent it from forming in the first place. Self-care practices can – and should! – be used in conjunction with all skincare treatments; they even deliver health benefits for those without acne problems.

For those with acne-prone skin, it can be tough finding a sunscreen that doesn’t clog pores and meshes well with your skincare regimen. Oily sunscreens often lead to breakouts. In addition to the wash, toner, moisturizer and treatments, the Clear Start kit includes an acne-safe (read: oil-free) sunscreen in its lineup — perfect for those wanting the best of both worlds in avoiding all types of red faces.


If you have acne that's not responding to self-care and over-the-counter treatments, make an appointment with your doctor. Early, effective treatment of acne reduces the risk of scarring and of lasting damage to your self-esteem. After an initial examination, your doctor may refer you to a specialist in the diagnosis and treatment of skin conditions (dermatologist).
If one of you is a night owl and the other an early riser, bedtime can become a source of conflict. It’s hard for a light sleeper to be jostled by their partner coming to bed four hours after them. Talk to your partner about negotiating some compromises. If you’re finding it difficult to agree on a bedtime, negotiate with your partner. Don’t come to bed before or after a certain time, giving the early bird a chance to fully fall asleep before the other comes in. Consider giving the night owl an eye mask to allow them to stay in bed while their partner gets up to start the day.
Sometimes birth control alone isn’t enough to really make a difference in hormonal acne. That’s when your doctor might recommend adding in an androgen blocker such as Spironalactone. Spiro (as it’s called) minimizes the amount of androgen hormones in circulation by blocking the receptors that bind with testosterone. When these pills are taken at the same time as an oral contraceptive, 90 percent of women see an improvement in breakouts, according to Linkner. The drug is sometimes prescribed to women with PCOS (polycystic ovarian syndrome) to relieve androgen-related symptoms like excessive hair growth, hypertension, oily skin, and acne.
Scientists initially hypothesized that acne represented a disease of the skin's hair follicle, and occurred due to blockage of the pore by sebum. During the 1880s, bacteria were observed by microscopy in skin samples affected by acne and were regarded as the causal agents of comedones, sebum production, and ultimately acne.[164] During the mid-twentieth century, dermatologists realized that no single hypothesized factor (sebum, bacteria, or excess keratin) could completely explain the disease.[164] This led to the current understanding that acne could be explained by a sequence of related events, beginning with blockage of the skin follicle by excessive dead skin cells, followed by bacterial invasion of the hair follicle pore, changes in sebum production, and inflammation.[164]

For UVA protection, a sunscreen with a high UVA protection of PA+++ or higher of PA++++ as recommended, especially to treat PIE. PPD is the UVA equivalent of SPF; use a sunscreen with a minimum of PPD20. The PA+ system has a + that corresponds to a tier of PPD protection. Of note, different countries use different PA systems. Japan and Taiwan changed their PA system to a 4+ tier system while Korea uses a 3+ tier system.
Whereas acne vulgaris clogs pores from the bottom up, acne inversa (or hidradenitis suppurativa) is a form of acne that clogs pores from the top down. It’s caused by excessively rapid skin growth, occluding the mouth of pores with shed skin cells. When the pores are blocked and clogged, they become inflamed and can create pimples and acne lesions. This form of acne is usually observed in intertriginous skin, where two skin areas may touch or rub together. Induced or aggravated by heat, moisture, maceration, friction and lack of air circulation. Examples of these areas include underarms, folds of the breasts, and between buttocks cheeks.

There are some foods that must be avoided for removing acne. These foods are milk, chocolates, sweets, desserts, cakes, fat and oil. You need to eat vitamins and minerals rich foods to get rid of acne. The examples of vitamins are vitamin A and C. These vitamins mainly found in orange and carrots. There is some other food such as eating organic foods. These foods are not harmful to acne.
Hypertrophic scars are uncommon, and are characterized by increased collagen content after the abnormal healing response.[32] They are described as firm and raised from the skin.[32][34] Hypertrophic scars remain within the original margins of the wound, whereas keloid scars can form scar tissue outside of these borders.[32] Keloid scars from acne occur more often in men and people with darker skin, and usually occur on the trunk of the body.[32]
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.
Eat healthily. Foods that are highly processed and contain a lot of oils greatly increase the amount of acne on your body. Getting the proper amount of nutrients from whole grains, fruits, vegetables, and protein help your skin to regenerate faster and limit unnecessary oil production. When at all possible, avoid foods that are processed or contain a lot of sugar (think junk foods).[11]
Chemical peels can be used to reduce the appearance of acne scars.[32] Mild peels include those using glycolic acid, lactic acid, salicylic acid, Jessner's solution, or a lower concentrations (20%) of trichloroacetic acid. These peels only affect the epidermal layer of the skin and can be useful in the treatment of superficial acne scars as well as skin pigmentation changes from inflammatory acne.[32] Higher concentrations of trichloroacetic acid (30–40%) are considered to be medium-strength peels and affect skin as deep as the papillary dermis.[32] Formulations of trichloroacetic acid concentrated to 50% or more are considered to be deep chemical peels.[32] Medium-strength and deep-strength chemical peels are more effective for deeper atrophic scars, but are more likely to cause side effects such as skin pigmentation changes, infection, and small white superficial cysts known as milia.[32]
Although the late stages of pregnancy are associated with an increase in sebaceous gland activity in the skin, pregnancy has not been reliably associated with worsened acne severity.[137] In general, topically applied medications are considered the first-line approach to acne treatment during pregnancy, as they have little systemic absorption and are therefore unlikely to harm a developing fetus.[137] Highly recommended therapies include topically applied benzoyl peroxide (category C) and azelaic acid (category B).[137] Salicylic acid carries a category C safety rating due to higher systemic absorption (9–25%), and an association between the use of anti-inflammatory medications in the third trimester and adverse effects to the developing fetus including too little amniotic fluid in the uterus and early closure of the babies' ductus arteriosus blood vessel.[47][137] Prolonged use of salicylic acid over significant areas of the skin or under occlusive dressings is not recommended as these methods increase systemic absorption and the potential for fetal harm.[137] Tretinoin (category C) and adapalene (category C) are very poorly absorbed, but certain studies have suggested teratogenic effects in the first trimester.[137] Due to persistent safety concerns, topical retinoids are not recommended for use during pregnancy.[138] In studies examining the effects of topical retinoids during pregnancy, fetal harm has not been seen in the second and third trimesters.[137] Retinoids contraindicated for use during pregnancy include the topical retinoid tazarotene, and oral retinoids isotretinoin and acitretin (all category X).[137] Spironolactone is relatively contraindicated for use during pregnancy due to its antiandrogen effects.[1] Finasteride is not recommended as it is highly teratogenic.[1]
Wear sunscreen everyday and do not tan. Ultraviolet Radiation is the number one cause of premature aging. It also leads to skin cancer in high enough doses. Treat the sun like the death ray that it is. Exposing your skin to harmful UVA and UVB rays damages skin and prolongs post inflammatory erythema(PIE)--red acne marks, as the sunlight stimulates pigment-producing cells.

Do a Google search for "how to get rid of acne fast" and you'll see plenty of websites telling you to eat better for clear skin. But are there really foods that cause acne, or is that an old wives' tale? Dermatologist Hilary Baldwin, MD, of the Acne Treatment and Research Centre in Morristown, New Jersey, says the answer isn't really simple at all. "The simple answer is, we don't know. So far studies have suggested that high-glycemic index diets (those with lots of white foods like potatoes, pasta, bread, rice and sweets), as well as diets high in skim-milk dairy products and whey protein supplements might be associated with worsening of existing acne but are less likely to cause acne," Baldwin says.
Sleeping next to your partner can be a satisfying experience and is typically seen as the mark of a stable, healthy home life. However, many more people struggle to share a bed with their partner than typically let on. Sleeping beside someone can decrease your sleep quality which negatively affects your life. Maybe you are light sleepers and you wake each other up throughout the night. Maybe one has a loud snoring habit that’s keeping the other awake. Maybe one is always crawling into bed in the early hours of the morning while the other likes to go to bed at 10 p.m.
All acne is not, actually, created equal. This makes perfect sense, seeing as there are so many factors — i.e. hygiene, hormones, and genetics — that can both lead to and exacerbate your breakouts. But knowledge is power, and just knowing that there are different types, and that each kind requires its own plan of attack, puts you ahead of the clear-skin curve. Once you figure out what you're working with, it gets far easier to treat. Here, your ultimate guide to identifying, and then taking down, every type of acne out there, according to dermatologists. Find out how to identify and deal with the different kinds of acne, including blackheads, whiteheads, blind pimples, and cystic zits.
