A major mechanism of acne-related skin inflammation is mediated by P. acnes's ability to bind and activate a class of immune system receptors known as toll-like receptors (TLRs), especially TLR2 and TLR4.[44][64][65] Activation of TLR2 and TLR4 by P. acnes leads to increased secretion of IL-1α, IL-8, and TNF-α.[44] Release of these inflammatory signals attracts various immune cells to the hair follicle including neutrophils, macrophages, and Th1 cells.[44] IL-1α stimulates increased skin cell activity and reproduction, which in turn fuels comedo development.[44] Furthermore, sebaceous gland cells produce more antimicrobial peptides, such as HBD1 and HBD2, in response to binding of TLR2 and TLR4.[44]

Considerations: Benzoyl peroxide is able to produce complete clearing of acne only when used in an adequate dosage and within a properly applied benzoyl peroxide regimen. Some dryness, redness, and itchiness is to be expected in the first few weeks of use.6 Scientists call this initial period the "hardening effect" of benzoyl peroxide. About 1-3% of people are allergic to benzoyl peroxide and experience an inflammation of the skin or severe crusting.3This should not be confused with the "hardening effect" of benzoyl peroxide. Benzoyl peroxide, like any other peroxide, can bleach hair and fabric.1

No single product can contain all of the necessary acne-fighting ingredients, despite what some may claim. Some chemicals shouldn’t be used together, while others work together to totally eradicate acne and all the blemishes that come with it. The best acne treatment systems can do that for you, but because everyone’s skin is unique, what works for one person may not work for another. The key lies in finding the right system, a combination of products, that work best for your unique skin.

Many treatment options for acne are available, including lifestyle changes, medications, and medical procedures. Eating fewer simple carbohydrates such as sugar may help.[7] Treatments applied directly to the affected skin, such as azelaic acid, benzoyl peroxide, and salicylic acid, are commonly used.[8] Antibiotics and retinoids are available in formulations that are applied to the skin and taken by mouth for the treatment of acne.[8] However, resistance to antibiotics may develop as a result of antibiotic therapy.[15] Several types of birth control pills help against acne in women.[8] Isotretinoin pills are usually reserved for severe acne due to greater potential side effects.[8][16] Early and aggressive treatment of acne is advocated by some in the medical community to decrease the overall long-term impact to individuals.[4]

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).
The good news about oily skin is that it is less likely to wrinkle, is more supple and doesn’t show its age as soon as other skin types. The bad news is that pores get clogged with oil more frequently. Using a daily gentle exfoliator can balance your skin’s tone and texture and keep pores unplugged. There are also anti-bacterial exfoliators that can speed up healing for breakouts.
This foaming cleanser is a soap-free gel that will clear away clogged pores without drying skin out. Designed not to disturb the skin’s natural moisture balance, the formula is made with astringent lavender extract to minimize pores and balance PH, while the anti-inflammatory balm mint extract soothes inflammation, giving skin a visibly clearer appearance. It uses alpha hydroxy acids and quillaja saponaria to deep clean pores and fight acne-causing bacteria.
All the dermatologists we talked to agreed that there is no one-size-fits-all solution to acne. Every patient responds to treatments differently, and sometimes it can get worse before it gets better. But with the help of your dermatologist, you can find an acne treatment regimen that works for you. And, yes, we do stress how helpful it is to work with a derm to get it right.
Spironolactone has relatively minor side effects, like low appetite, weakness, or cramping, but there’s one major exception: spironolactone comes with a black box warning about its cancer-causing effects. The FDA is required to include this label based on a study conducted in the 1950s that found carcinogenic properties in the spironolactone given to rats in an experiment. However, the dose of spironolactone used in this study was nearly 500 times higher than the dose currently prescribed, and no studies since have found anything carcinogenic about spironolactone. Because of this, most dermatologists feel comfortable prescribing spironolactone for acne. Still, it’s something to be aware of before you take it. Additionally, those with low blood pressure or kidney conditions are likely not good candidates for spironolactone and may want to explore other acne treatment options.

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]
Medical conditions that commonly cause a high-androgen state, such as polycystic ovary syndrome, congenital adrenal hyperplasia, and androgen-secreting tumors, can cause acne in affected individuals.[44][45] Conversely, people who lack androgenic hormones or are insensitive to the effects of androgens rarely have acne.[44] An increase in androgen and oily sebum synthesis may be seen during pregnancy.[45][46] Acne can be a side effect of testosterone replacement therapy or of anabolic steroid use.[1][47] Over-the-counter bodybuilding and dietary supplements are commonly found to contain illegally added anabolic steroids.[1][48]
What it is: Spironolactone is a prescription medication in tablet form used to treat certain patients with hyperaldosteronism (the body produces too much aldosterone, a naturally occurring hormone), low potassium levels, and in patients with edema (fluid retention) caused by various conditions.1 Learn more from the U.S. National Library of Medicine.
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] As of 2012, evidence for various light therapies was insufficient to recommend them for routine use.[8] 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;[76][143] 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.[144] Typical side effects include skin peeling, temporary reddening of the skin, swelling, and postinflammatory hyperpigmentation.[10]
Accutane (isotretinoin) has a mixed reputation, but among dermatologists it’s the finisher for patients with severe acne. “If you have an acne patient that doesn’t respond to anything, [Accutane] can really be a game changer,” board-certified dermatologist Adam Friedman tells SELF. Accutane is an oral retinoid, and it has all the same benefits of a topical retinol but is even more effective.

Glycolic acid is another chemical exfoliant that dissolves the structural lipids that hold dead skin cells and bind them to the surface. But aside from this, studies have also shown that glycolic acid effectively encourages and stimulates the production of collagen and elastin, restoring damaged skin faster and reducing signs of environmental damage with continuous use.
Having a specific type of skin now doesn’t mean you will be stuck with it the rest of your life. As you get older, your skin can change. It may be oily when you are younger but become dry as you age. Plus, skin can become more or less sensitive over time. It’s always a good idea to retest for your skin type if you notice any changes. We’ve included a guide above to help you recognize what kind of acne you have, what the average causes are, and how to treat it (or at least not aggravate it).
How to Handle It: Speaking of touching, don't! Picking it, squeezing it, or poking at it will only worsen the situation. These may disappear on their own after a few days. Otherwise, Zeichner suggests visiting your dermatologist for a shot of cortisone, which will reduce inflammation and shrink it in just 24 to 48 hours. But if a last-minute appointment isn't in the cards, play mad scientist. First, ice the area, and then apply salicylic acid gel, benzoyl peroxide gel, and 1 percent hydrocortisone cream. The combo will calm skin, kill bacteria, and draw out excess oil from the pimple — all things necessary to take this down, says Zeichner.
If you have oily, tight skin and tend to get age spots or sun spots, try an exfoliant made with glycolic acid right after you cleanse your skin, no more than 4 or 5 times a week. Aveeno Positively Radiant Cleansing Pads provides just a “dab” of exfoliant that will help lighten the spots without irritating your skin (which over the long run would create new brown spots).

Considerations: Because tazarotene is a retinoid (vitamin A derivative), like Accutane, it should not be used by women who are pregnant because of potential harm to the fetus. Exposure to sunlight should be avoided. Wind or cold may be more irritating when taking tazarotene. Side effects occured in 10-30% of patients and included dry peeling skin, burning, stinging, dry skin, redness, and itchiness.
It is widely suspected that the anaerobic bacterial species Propionibacterium acnes (P. acnes) contributes to the development of acne, but its exact role is not well understood.[2] There are specific sub-strains of P. acnes associated with normal skin, and moderate or severe inflammatory acne.[49] It is unclear whether these undesirable strains evolve on-site or are acquired, or possibly both depending on the person. These strains have the capability of changing, perpetuating, or adapting to the abnormal cycle of inflammation, oil production, and inadequate sloughing of dead skin cells from acne pores. Infection with the parasitic mite Demodex is associated with the development of acne.[29][50] It is unclear whether eradication of the mite improves acne.[50]

Acne usually improves around the age of 20, but may persist into adulthood.[75] Permanent physical scarring may occur.[19] There is good evidence to support the idea that acne and associated scarring negatively affect a person's psychological state, worsen mood, lower self-esteem, and are associated with a higher risk of anxiety disorders, depression, and suicidal thoughts.[3][30][50] Another psychological complication of acne vulgaris is acne excoriée, which occurs when a person persistently picks and scratches pimples, irrespective of the severity of their acne.[61][155] This can lead to significant scarring, changes in the affected person's skin pigmentation, and a cyclic worsening of the affected person's anxiety about their appearance.[61] Rare complications from acne or its treatment include the formation of pyogenic granulomas, osteoma cutis, and solid facial edema.[156] Early and aggressive treatment of acne is advocated by some in the medical community to reduce the chances of these poor outcomes.[4]
Isotretinoin is an oral retinoid that is very effective for severe nodular acne, and moderate acne that is stubborn to other treatments.[1][19] 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.[19] About 20% of patients require a second course.[19] 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][19] Isotretinoin is superior to antibiotics or placebo in reducing acne lesions.[16] The frequency of adverse events was about twice as high with isotretinoin, although these were mostly dryness-related events.[16] No increased risk of suicide or depression was conclusively found.[16] Isotretinoin use in women of childbearing age is regulated due to its known harmful effects in pregnancy.[19] 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.[19] 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]
Considerations: Side effects are generally mild and short lived. Most common, in 1-5% of people are itching, burning, stinging, and tingling. Other side effects were reported in less than 1% of people. There have been a few reports from darker skinned people of lightening of the skin. Azelaic acid has not been well studied in people with dark complexions.1
Antiandrogens such as cyproterone acetate and spironolactone have been used successfully to treat acne, especially in women with signs of excessive androgen production such as increased hairiness or skin production of sebum, or baldness.[10][46] Spironolactone is an effective treatment for acne in adult women, but unlike combined birth control pills, is not approved by the United States Food and Drug Administration for this purpose.[1][35][100] The medication is primarily used as an aldosterone antagonist and is thought to be a useful acne treatment due to its ability to additionally block the androgen receptor at higher doses.[35] Alone or in combination with a birth control pill, spironolactone has shown a 33 to 85% reduction in acne lesions in women.[91] The effectiveness of spironolactone for acne appears to be dose-dependent.[91] High-dose cyproterone acetate alone has been found to decrease symptoms of acne in women by 75 to 90% within 3 months.[101] It is usually combined with an estrogen to avoid menstrual irregularities and estrogen deficiency.[102] The medication has also been found to be effective in the treatment of acne in males, with one study finding that a high dosage reduced inflammatory acne lesions by 73%.[103][104] However, the side effects of cyproterone acetate in males, such as gynecomastia, sexual dysfunction, and decreased bone mineral density, make its use for acne in this sex impractical in most cases.[103][104][105] Hormonal therapies should not be used to treat acne during pregnancy or lactation as they have been associated with birth disorders such as hypospadias, and feminization of the male babies.[46] In addition, women who are sexually active and who can or may become pregnant should use an effective method of contraception to prevent pregnancy while taking an antiandrogen.[106] Antiandrogens are often combined with birth control pills for this reason, which can result in additive efficacy.[35][107]

Considerations: Benzoyl peroxide is able to produce complete clearing of acne only when used in an adequate dosage and within a properly applied benzoyl peroxide regimen. Some dryness, redness, and itchiness is to be expected in the first few weeks of use.6 Scientists call this initial period the "hardening effect" of benzoyl peroxide. About 1-3% of people are allergic to benzoyl peroxide and experience an inflammation of the skin or severe crusting.3This should not be confused with the "hardening effect" of benzoyl peroxide. Benzoyl peroxide, like any other peroxide, can bleach hair and fabric.1
Keep in mind that even if some products market themselves toward severe acne breakouts, all the kits we looked at are definitely designed for mild to moderate acne. Not sure if you fit on that scale? You’re not alone! When you’re in the middle of a breakout, all acne seems severe, so it can be difficult to self-diagnose your symptoms. We talked to dermatologists and cosmetic chemists to better understand the differences between the various types of acne (see below).
Azelaic acid is a natural acid that is derived from various grains like wheat and barley. It helps reduce acne by preventing skin cell buildup, killing p. acnes bacteria, and reducing inflammation4. This means it can help reduce all kinds of acne, from blackheads to pimples. Blackheads and whiteheads form when dead skin cells combine with sebum, the oil our skin naturally produces and get clogged in a pore. To get rid of this kind of acne, it helps to regulate your skin cell production and exfoliate your skin to remove excess dead skin cells. Azelaic acid is a great way to do both of these things, while also decreasing inflammation and killing bacteria. When the skin is inflamed, it swells slightly, causing the pores to constrict. This traps dead skin cells and sebum inside, leading to blackheads and whiteheads, and if bacteria get trapped as well, then pimples can also form.

Tea Tree Oil – Another anti-bacterial ingredient that is common in over-the-counter treatments, tea tree oil combats acne-causing bacteria. While the FDA hasn’t officially approved it for acne treatment, some dermatologists say it’s almost as effective as benzoyl peroxide for clearing skin, although it doesn’t work quite as fast. It can be used for spot treatment as well.
Azelaic acid has been shown to be effective for mild to moderate acne when applied topically at a 20% concentration.[66][129] Treatment twice daily for six months is necessary, and is as effective as topical benzoyl peroxide 5%, isotretinoin 0.05%, and erythromycin 2%.[130] Azelaic acid is thought to be an effective acne treatment due to its ability to reduce skin cell accumulation in the follicle, and its antibacterial and anti-inflammatory properties.[66] It has a slight skin-lightening effect due to its ability to inhibit melanin synthesis, and is therefore useful in treating of individuals with acne who are also affected by postinflammatory hyperpigmentation.[1] Azelaic acid may cause skin irritation but is otherwise very safe.[131] It is less effective and more expensive than retinoids.[1]
Although there is not enough research to determine if certain foods cause breakouts, there are certain changes you can make to your diet to help prevent them. For breakfast, switching to plain oatmeal that has only been sweetened with fresh fruit can help prevent excessive androgen production. When you eat fish, opt for salmon, which is high in omega-3s. One omega-3 called DHA is an anti-inflammatory. Snacking on sunflower seeds can give you more vitamin E in your diet. Vitamin E helps the immune system fight off bacteria before inflammation and cysts occur. Finally, make sure you stay hydrated by drinking plenty of water each day. Your body needs almost half a gallon each day.

Have you tried treating your acne with no luck? You might simply be using the wrong product for the type you have. Whether you have periodic breakouts or more stubborn cystic acne, there's a solution. We asked Dr. Neal Schultz, an NYC dermatologist, to share the best treatments for every type of acne. Read on for his expert product recommendations, along with some editor favorites, that'll give you clear skin in no time.
Thanks to its special MicroClear technology, Neutrogena Oil-Free Acne and Redness Facial Cleanser helps boost the delivery of active ingredient salicylic acid, in order to help reduce the appearance of acne. The inclusion of aloe and chamomile help to calm irritation while visibly reducing facial redness, a source of emotional stress for many acne sufferers.

Even though scientists know how pimples and blackheads are formed, they are still not sure what causes you to have a body full of blemishes and the guy sitting next to you not to have a single spot on his face? It’s probably related to hereditary factors. If your parents dealt with acne when they were younger, you’re more likely to struggle with acne, too.
