Globally, acne affects approximately 650 million people, or about 9.4% of the population, as of 2010.[158] It affects nearly 90% of people in Western societies during their teenage years, but can occur before adolescence and may persist into adulthood.[19][20][23] While acne that first develops between the ages of 21 and 25 is uncommon, it affects 54% of women and 40% of men older than 25 years of age,[47][159] and has a lifetime prevalence of 85%.[47] About 20% of those affected have moderate or severe cases.[2] It is slightly more common in females than males (9.8% versus 9.0%).[158] In those over 40 years old, 1% of males and 5% of females still have problems.[20]

It's a common misconception that those with oily skin shouldn't moisturize. Be sure you're treating your entire face to a full routine and not solely relying on spot treatments to battle your breakouts. If your acne comes with a side of oil, this is your best bet for a daily moisturizer. It contains panadoxine, a vitamin B6 derivative that improves skin’s overall healthy balance by visually minimizing pore size and shine.
Many different treatments exist for acne. These include alpha hydroxy acid, anti-androgen medications, antibiotics, antiseborrheic medications, azelaic acid, benzoyl peroxide, hormonal treatments, keratolytic soaps, nicotinamide, retinoids, and salicylic acid.[75] They are believed to work in at least four different ways, including the following: reducing inflammation, hormonal manipulation, killing P. acnes, and normalizing skin cell shedding and sebum production in the pore to prevent blockage.[76] Common treatments include topical therapies such as antibiotics, benzoyl peroxide, and retinoids, and systemic therapies including antibiotics, hormonal agents, and oral retinoids.[20][77]
Light therapy is a treatment method that involves delivering certain specific wavelengths of light to an area of skin affected by acne. Both regular and laser light have been used. When regular light is used immediately following the application of a sensitizing substance to the skin such as aminolevulinic acid or methyl aminolevulinate, the treatment is referred to as photodynamic therapy (PDT).[10][129] PDT has the most supporting evidence of all light therapies.[78] Many different types of nonablative lasers (i.e., lasers that do not vaporize the top layer of the skin but rather induce a physiologic response in the skin from the light) have been used to treat acne, including those that use infrared wavelengths of light. Ablative lasers (such as CO2 and fractional types) have also been used to treat active acne and its scars. When ablative lasers are used, the treatment is often referred to as laser resurfacing because, as mentioned previously, the entire upper layers of the skin are vaporized.[140] Ablative lasers are associated with higher rates of adverse effects compared with nonablative lasers, with examples being postinflammatory hyperpigmentation, persistent facial redness, and persistent pain.[8][141][142] Physiologically, certain wavelengths of light, used with or without accompanying topical chemicals, are thought to kill bacteria and decrease the size and activity of the glands that produce sebum.[129] The evidence for light therapy as a treatment for acne is weak and inconclusive.[8][143] Disadvantages of light therapy can include its cost, the need for multiple visits, time required to complete the procedure(s), and pain associated with some of the treatment modalities.[10] Various light therapies appear to provide a short-term benefit, but data for long-term outcomes, and for outcomes in those with severe acne, are sparse;[144] it may have a role for individuals whose acne has been resistant to topical medications.[10] A 2016 meta-analysis was unable to conclude whether light therapies were more beneficial than placebo or no treatment, nor how long potential benefits lasted.[145] Typical side effects include skin peeling, temporary reddening of the skin, swelling, and postinflammatory hyperpigmentation.[10]
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]
Flutamide, a pure antagonist of the androgen receptor, is effective in the treatment of acne in women.[101][108] It has generally been found to reduce symptoms of acne by 80 or 90% even at low doses, with several studies showing complete acne clearance.[101][109][110] In one study, flutamide decreased acne scores by 80% within 3 months, whereas spironolactone decreased symptoms by only 40% in the same time period.[110][111][112] In a large long-term study, 97% of women reported satisfaction with the control of their acne with flutamide.[113] Although effective, flutamide has a risk of serious liver toxicity, and cases of death in women taking even low doses of the medication to treat androgen-dependent skin and hair conditions have occurred.[114] As such, the use of flutamide for acne has become increasingly limited,[113][115][116] and it has been argued that continued use of flutamide for such purposes is unethical.[114] Bicalutamide, a pure androgen receptor antagonist with the same mechanism as flutamide and with comparable or superior antiandrogenic efficacy but without its risk of liver toxicity, is a potential alternative to flutamide in the treatment of androgen-dependent skin and hair conditions in women.[106][117][118][119]
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.

There are two big guns used to take down acne, and they're both great at doing entirely different things. Salicylic acid is a beta hydroxy acid that comes from willow bark and works primarily as an exfoliator, breaking down fatty acids like sebum so your pores don’t clog. (Glycolic acid works similarly but is less effective.) These acids are effective on comedones — whiteheads, blackheads, and other non-red bumps.
Several scales exist to grade the severity of acne vulgaris, but no single technique has been universally accepted as the diagnostic standard.[68][69] Cook's acne grading scale uses photographs to grade severity from 0 to 8 (0 being the least severe and 8 being the most severe). This scale was the first to use a standardized photographic protocol to assess acne severity; since its creation in 1979, the scale has undergone several revisions.[69] The Leeds acne grading technique counts acne lesions on the face, back, and chest and categorizes them as inflammatory or non-inflammatory. Leeds scores range from 0 (least severe) to 10 (most severe) though modified scales have a maximum score of 12.[69][70] The Pillsbury acne grading scale simply classifies the severity of the acne from grade 1 (least severe) to grade 4 (most severe).[68][71]
Acne, also known as acne vulgaris, is a long-term skin disease that occurs when hair follicles are clogged with dead skin cells and oil from the skin.[10] It is characterized by blackheads or whiteheads, pimples, oily skin, and possible scarring.[1][2][11] It primarily affects areas of the skin with a relatively high number of oil glands, including the face, upper part of the chest, and back.[12] The resulting appearance can lead to anxiety, reduced self-esteem and, in extreme cases, depression or thoughts of suicide.[3][4]
Oral antibiotics are recommended for no longer than three months as antibiotic courses exceeding this duration are associated with the development of antibiotic resistance and show no clear benefit over shorter courses.[87] Furthermore, if long-term oral antibiotics beyond three months are thought to be necessary, it is recommended that benzoyl peroxide and/or a retinoid be used at the same time to limit the risk of C. acnes developing antibiotic resistance.[87]

Cystic Acne: The most severe type of acne, cystic acne requires dermatological care and prescription acne medication to treat. Even the best acne products available over the counter are no match for this painful condition in which the area of the outbreak becomes inflamed, but not infected. Cystic acne can result in permanent scarring. However, it's important to know that all acne lesions can scar. Scarring is related to size, amount of inflammation, genetics and delay in therapy.
Exercise not only helps you with fitness, but it can help reduce acne-prone skin irritations. That’s right, add its use on how to get rid of pimples to the list of exercise benefits. Exercise offers stress relief while getting the blood circulating. This blood-pumping activity sends oxygen to your skin cells, which helps remove dead cells from the body.

The path to clear skin is often one of trial and error; you might need to try several acne remedies before you find the right treatment for the types of acne affecting your skin. Before trying acne medication, you may prefer to give different natural acne treatment options a chance. While there's no research supporting the effective use of natural acne treatments, here are two popular options that you may want to try.

Topical antibiotics deemed safe during pregnancy include clindamycin, erythromycin, and metronidazole (all category B), due to negligible systemic absorption.[47][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.[47][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.[20] 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]
Acne vulgaris is a chronic skin disease of the pilosebaceous unit and develops due to blockages in the skin's hair follicles. These blockages are thought to occur as a result of the following four abnormal processes: a higher than normal amount of oily sebum production (influenced by androgens), excessive deposition of the protein keratin leading to comedo formation, colonization of the follicle by Cutibacterium acnes (C. acnes) bacteria, and the local release of pro-inflammatory chemicals in the skin.[50]
Accutane is especially good for cystic acne in women and body acne in men. “Oral vitamin A basically shuts down your sebaceous glands. If you suppress [them] for a long enough period, you can cure someone of their acne, and about 50 percent do hit that cure rate,” says Linkner. A course of Accutane can take about six to nine months. Sometimes patients need to repeat the course at a higher dosage in order to truly eliminate acne.

Processed Foods: Ingredients found in processed and junk food such as chips, breakfast cereals and white bread are acne-inducing villains. Preservatives and additives can trigger hormonal fluctuations, and greasy fast food leads to inflammation all over your body – including your face. Refined grains are quickly broken down and turned into sugar, which creates a terrible effect on skin by aggravating acne.

If you’re used to seeing advertisements for acne treatments using five or six different products to clear up blemishes, you might be surprised that a simple three-step kit is our top pick. In fact, we favored Paula’s Choice for its simplicity. This twice-daily, three-step kit — which includes a cleanser, an anti-redness exfoliant, and a leave-on treatment — is concise without cutting corners.

Washing your face with regular soap isn't enough to make acne better. The best face wash for acne is effective at removing oil and dirt, but still gentle enough to use regularly without overdrying your skin. Look for topical acne medication ingredients salicylic acid and/or benzoyl peroxide in your face wash and use gentle, nonabrasive cleansing techniques.
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.

Another once-daily gel your dermatologist might prescribe for acne is Aczone 7.5 percent. The active ingredient, dapsone, is both antimicrobial and anti-inflammatory, and it’s proven to help with blackheads, whiteheads, and deeper painful pimples. Oftentimes, Aczone is used alongside other acne treatments. And like many of those other remedies, Aczone can cause skin to dry out.


How to Handle It: Think of these as bigger, pissed-off whiteheads. Your best bet, says Zeichner, is to stock up on benzoyl peroxide, which kills the bacteria. A spot treatment like Murad Acne Spot Fast Fix ($22) should do the trick. Also, try not to pop them — as tempting as that may be. Since they're inflamed, they're more likely to scar if you go the DIY route.
C. acnes also provokes skin inflammation by altering the fatty composition of oily sebum.[45] Oxidation of the lipid squalene by C. acnes is of particular importance. Squalene oxidation activates NF-κB (a protein complex) and consequently increases IL-1α levels.[45] Additionally, squalene oxidation leads to increased activity of the 5-lipoxygenase enzyme responsible for conversion of arachidonic acid to leukotriene B4 (LTB4).[45] LTB4 promotes skin inflammation by acting on the peroxisome proliferator-activated receptor alpha (PPARα) protein.[45] PPARα increases activity of activator protein 1 (AP-1) and NF-κB, thereby leading to the recruitment of inflammatory T cells.[45] The inflammatory properties of C. acnes can be further explained by the bacterium's ability to convert sebum triglycerides to pro-inflammatory free fatty acids via secretion of the enzyme lipase.[45] These free fatty acids spur production of cathelicidin, HBD1, and HBD2, thus leading to further inflammation.[45]
Hormonal activity, such as occurs during menstrual cycles and puberty, may contribute to the formation of acne. During puberty, an increase in sex hormones called androgens causes the skin follicle glands to grow larger and make more oily sebum.[12] Several hormones have been linked to acne, including the androgens testosterone, dihydrotestosterone (DHT), and dehydroepiandrosterone (DHEA); high levels of growth hormone (GH) and insulin-like growth factor 1 (IGF-1) have also been associated with worsened acne.[42] Both androgens and IGF-1 seem to be essential for acne to occur, as acne does not develop in individuals with complete androgen insensitivity syndrome (CAIS) or Laron syndrome (insensitivity to GH, resulting in very low IGF-1 levels).[43][44]
Many different treatments exist for acne. These include alpha hydroxy acid, anti-androgen medications, antibiotics, antiseborrheic medications, azelaic acid, benzoyl peroxide, hormonal treatments, keratolytic soaps, nicotinamide, retinoids, and salicylic acid.[75] They are believed to work in at least four different ways, including the following: reducing inflammation, hormonal manipulation, killing P. acnes, and normalizing skin cell shedding and sebum production in the pore to prevent blockage.[76] Common treatments include topical therapies such as antibiotics, benzoyl peroxide, and retinoids, and systemic therapies including antibiotics, hormonal agents, and oral retinoids.[20][77]

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.
