And though none of the experts we spoke to specifically called this out, writer Frankie May Wong declared this salicylic-acid-enhanced Medik8 gel as her cystic-acne Holy Grail. She uses it sparingly to avoid it losing its efficacy, but thanks its blend of acne-fighting ingredients for her clear skin and the lack of scarring thereafter: “Another reason the Beta Gel seemed to work miracles could’ve been the combination of dioic acid (a rarer ingredient that otherwise only appears in the pricey but raved-about SkinCeuticals Blemish + Age Defense serum), azelaic acid, and niacinamide.”
No one knows exactly what causes acne. Hormone changes, such as those during the teenage years and pregnancy, probably play a role. There are many myths about what causes acne. Chocolate and greasy foods are often blamed, but there is little evidence that foods have much effect on acne in most people. Another common myth is that dirty skin causes acne; however, blackheads and pimples are not caused by dirt. Stress doesn't cause acne, but stress can make it worse.
Salicylic acid is a topically applied beta-hydroxy acid that stops bacteria from reproducing and has keratolytic properties.[131][132] It opens obstructed skin pores and promotes shedding of epithelial skin cells.[131] Salicylic acid is known to be less effective than retinoid therapy.[20] Dry skin is the most commonly seen side effect with topical application, though darkening of the skin has been observed in individuals with darker skin types.[1]

What to know about hormonal imbalances While it is natural to experience hormonal imbalances at certain times in life, such as puberty, menopause, and pregnancy, some hormonal changes are related to underlying medical conditions. This article looks at the causes and symptoms of hormonal imbalances in men and women, as well as treatment and home remedies. Read now

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.


Post-inflammatory hyperpigmentation is not an acne scar, but a red, pink, brown or tan skin discoloration where acne has previously flared up. It'll usually disappear on its own in a year or so. Many skin lightening products claim to help reduce the visibility of these acne "scars." Their active ingredient, hydroquinone, works to slow melanin production and can reduce dark brown marks, but melanin isn't the cause of red and pink acne discolorations. A better option is to use the best foundation for acne prone skin you can find to hide the marks until they naturally fade away.

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.
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]
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.[45][46] Conversely, people who lack androgenic hormones or are insensitive to the effects of androgens rarely have acne.[45] An increase in androgen and oily sebum synthesis may be seen during pregnancy.[46][47] Acne can be a side effect of testosterone replacement therapy or of anabolic steroid use.[1][48] Over-the-counter bodybuilding and dietary supplements are commonly found to contain illegally added anabolic steroids.[1][49]
A 2013 study on acne vulgaris in The Nurse Practitioner concurred that a multidimensional approach to acne is usually necessary because most people have a combination of symptoms. Based on the advice of dermatologists and aestheticians, we turned our focus to regimen sets, analyzing the ingredients of more than 40 kits before finding our top picks.

Globally, acne affects approximately 650 million people, or about 9.4% of the population, as of 2010.[157] 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][158] 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%).[157] In those over 40 years old, 1% of males and 5% of females still have problems.[20]

It is widely suspected that the anaerobic bacterial species Cutibacterium acnes (formerly Propionibacterium. acnes) contributes to the development of acne, but its exact role is not well understood.[2] There are specific sub-strains of C. acnes associated with normal skin, and moderate or severe inflammatory acne.[50] 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.[30][51] It is unclear whether eradication of the mite improves acne.[51]
The severity of acne vulgaris (Gr. ἀκµή, "point" + L. vulgaris, "common")[24] can be classified as mild, moderate, or severe as this helps to determine an appropriate treatment regimen.[20] There is no universally accepted scale for grading acne severity.[15] Mild acne is classically defined by the presence of clogged skin follicles (known as comedones) limited to the face with occasional inflammatory lesions.[20] Moderate severity acne is said to occur when a higher number of inflammatory papules and pustules occur on the face compared to mild cases of acne and are found on the trunk of the body.[20] Severe acne is said to occur when nodules (the painful 'bumps' lying under the skin) are the characteristic facial lesions and involvement of the trunk is extensive.[20][25]

Coconut oil is all the rage, with uses ranging from hair conditioning to cooking. But some swear by it as a natural acne treatment. To use coconut oil as an acne treatment, you can include it as part of a healthy diet. The fatty acids like lauric acid and caprylic acid are metabolized into antibacterial agents in the body. Or, you can apply a very small amount and rub directly onto your skin after cleansing for an extra hydrating boost.
The Anti-Redness Exfoliating Solution is mostly water, but its 2 percent salicylic acid is enough to eat through oil and remove the dead skin cells clogging your pores — and it boasts a higher concentration than nearly every other kit we looked at. Sodium hyaluronate, the super-moisturizing humectant we fell in love with in our review on the Best Face Moisturizer, also caught our eye sitting smack dab in the middle of the ingredients list.

Combined oral contraceptives. Four combined oral contraceptives are approved by the FDA for acne therapy in women who also wish to use them for contraception. They are products that combine estrogen and progestin (Ortho Tri-Cyclen, Yaz, others). You may not see the benefit of this treatment for a few months, so using other acne medications with it the first few weeks may help.
