P. acnes also provokes skin inflammation by altering the fatty composition of oily sebum.[44] Oxidation of the lipid squalene by P. acnes is of particular importance. Squalene oxidation activates NF-κB (a protein complex) and consequently increases IL-1α levels.[44] Additionally, squalene oxidation leads to increased activity of the 5-lipoxygenase enzyme responsible for conversion of arachidonic acid to leukotriene B4 (LTB4).[44] LTB4 promotes skin inflammation by acting on the peroxisome proliferator-activated receptor alpha (PPARα) protein.[44] PPARα increases activity of activator protein 1 (AP-1) and NF-κB, thereby leading to the recruitment of inflammatory T cells.[44] The inflammatory properties of P. 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.[44] These free fatty acids spur production of cathelicidin, HBD1, and HBD2, thus leading to further inflammation.[44]
The Pore Normalizing Cleanser is designed just to cleanse, not treat, which is a good thing: The Nurse Practitioner study emphasizes the importance of washing with mild cleansers in conjunction with topical acne medications to combat or avoid excessive skin irritation. This one is water-based and fragrance-free, and uses sodium laureth sulfate (as opposed to its harsh cousin sodium lauryl sulfate) to eliminate any chance for irritation.
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.
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]

You will see the results from the top performers in the comparison chart. Although any of these treatment systems can safely and effectively help reduce blemishes, Exposed Skin Care stands above the rest as the best acne treatment system. All the products are safe and regulated by the FDA, but Exposed Skin Care also works for a variety of skin types, including sensitive skin. The thing we like most about Exposed Skin Care is the 6-month money back guarantee. Many blemish products expect you to use them for six to eight weeks before you see results and then only provide you with a 1-month guarantee. If you purchase individual products in the store, you are stuck with them, since many do not come with any guarantees. Exposed Skin Care allows you to give their product a fair trial before you decide if it is working for your skin.
Misperceptions about acne's causative and aggravating factors are common, and those affected by it are often blamed for their condition.[176] Such blame can worsen the affected person's sense of self-esteem.[176] Until the 20th century, even among dermatologists, the list of causes was believed to include excessive sexual thoughts and masturbation.[165] Dermatology's association with sexually transmitted infections, especially syphilis, contributed to the stigma.[165]

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.

A complete skin care regimen to control acne usually starts with washing. The ideal face wash creates a soft creamy lather in warm water. It rinses off dirt, excess oil, and makeup, leaving the face ready for the next step in daily skin care, whether that is toner, moisturizer, exfoliant, sunblock, or more makeup. It is fragrance-free, and it does not create a foam, film, or tingly sensation on the face. Any product that foams and suds vigorously, like a detergent, is a strict no-no for acne treatment, especially on dry skin.
For some, the right dosage can be found over-the-counter in concentrations as low as 2.5 percent or up to 10 percent, but for others, a prescription dosage is needed to see the best results. Prescription doses rarely go over 10 percent, as benzoyl peroxide is known to cause stinging, burning, itching, flaking, peeling, and redness2 when used in concentrations over 5 percent, but they may combine the benzoyl peroxide with other acne medications.

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.[19][77]
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]

Alpha-Hydroxy Acids – These are synthetic acids derived from sugary fruits that remove dead skin cells3 while reducing inflammation. The two common types that can be found in over-the-counter acne treatments are glycolic acid and lactic acid. Another benefit of these acids is that they improve the appearance of your acne scars and make your pores look smaller by stimulating the growth of new, healthy skin.
Recommended therapies for first-line use in acne vulgaris treatment include topical retinoids, benzoyl peroxide, and topical or oral antibiotics.[78] Procedures such as light therapy and laser therapy are not considered to be first-line treatments and typically have an adjunctive role due to their high cost and limited evidence of efficacy.[77] Medications for acne work by targeting the early stages of comedo formation and are generally ineffective for visible skin lesions; improvement in the appearance of acne is typically expected between six and eight weeks after starting therapy.[1]
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.
Benzoyl peroxide attacks the P. acnes bacteria. However, one of its main side effects is dryness: If you’re going to use anything with benzoyl peroxide, make sure to moisturize afterwards. Sulfur and azelaic acid are less common and less severe alternatives to benzoyl peroxide. Dr. Peter Lio, assistant professor of clinical dermatology at Northwestern University, says sulfur-based treatments are “a good fit for patients who can’t tolerate the side effects of benzoyl peroxide.”
