Acne vulgaris and its resultant scars have been associated with significant social and academic difficulties that can last into adulthood, including difficulties obtaining employment.[30][177] Until the 1930s, it was largely seen as a trivial problem among middle-class girls – a trivial problem, because, unlike smallpox and tuberculosis, no one died from it, and a feminine problem, because boys were much less likely to seek medical assistance for it.[165] During the Great Depression, dermatologists discovered that young men with acne had difficulty obtaining jobs, and during World War II, some soldiers in tropical climates developed such severe and widespread tropical acne on their bodies that they were declared medically unfit for duty.[165]

Combined oral contraceptive pills contain progesterone and estrogen and help to balance out the levels of testosterone in the body12 One obvious effect of this is birth control, but dermatologists have also found it very useful for treating hormonal acne. Testosterone doesn’t directly cause acne, but when hormone levels fluctuate and testosterone increases above its baseline level, it can lead to increased acne for some. This is because increases in testosterone and other androgens leads to an increase in sebum production, which can cause more clogged pores and more p. acnes bacteria, leading to blackheads, whiteheads, pimples, or even cysts.


Exposed Skin Care: Exposed Skin Care products include benzoyl peroxide, salicylic acid, and azelaic acid (see below for more details), all at low concentrations that are safe for all skin types. Plus they also incorporate powerful natural ingredients, like tea tree oil, vitamin E, and green tea extract. Before jumping straight to the strongest (and harshest) prescription treatment available, we highly recommend giving this gentle but effective brand a try for a few weeks. If it doesn’t work, you can always send your empty product bottles back to the company and they will reimburse you in full.
Contrary to the marketing promises of “blemish banishers” and “zit zappers,” immediate results are not the trademark of acne treatments — a frustrating truth to anyone suffering through a breakout. And while pimples are personal (your stress-induced spots will look and act differently than your best friend’s breakout), the best acne treatments will include a regimen of products to hit all of acne’s root causes. We tested 43 kits to find the most well-rounded breakout-fighting solutions on the market.
Retinoids and retinoid-like drugs. These come as creams, gels and lotions. Retinoid drugs are derived from vitamin A and include tretinoin (Avita, Retin-A, others), adapalene (Differin) and tazarotene (Tazorac, Avage). You apply this medication in the evening, beginning with three times a week, then daily as your skin becomes used to it. It works by preventing plugging of the hair follicles.

Dermal or subcutaneous fillers are substances injected into the skin to improve the appearance of acne scars. Fillers are used to increase natural collagen production in the skin and to increase skin volume and decrease the depth of acne scars.[145] Examples of fillers used for this purpose include hyaluronic acid; poly(methyl methacrylate) microspheres with collagen; human and bovine collagen derivatives, and fat harvested from the person's own body (autologous fat transfer).[145]

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]

Our favorite for banishing blemishes on the fly, Glossier's zit stick is not only effective, but it's portable. Just stash it in your purse for any unexpected breakouts! Packed with acne-fighting benzoyl peroxide, this convenient roll-on works extremely quickly. In a clinical trial, 83% of test subjects said that it lessened the appearance of pimples in just 3 hours. We've tried it ourselves and can confirm the 3-hour claim is true.
We've already waxed poetic about the wonders of this brand's body sheet masks (one editor even wore hers topless!), which means we had high hopes for its citrus-scented cleanser. Luckily, it fulfilled its acne-fighting promises. Made with tea tree extract to target excess oil, salicylic acid to gently exfoliate skin cells, and niacinamide to smooth post-breakout texture, this formula targets every stage of a breakout.
Acne inversa (L. invertō, "upside down") and acne rosacea (rosa, "rose-colored" + -āceus, "forming") are not true forms of acne and respectively refer to the skin conditions hidradenitis suppurativa (HS) and rosacea.[25][26][27] Although HS shares certain common features with acne vulgaris, such as a tendency to clog skin follicles with skin cell debris, the condition otherwise lacks the defining features of acne and is therefore considered a distinct skin disorder.[25]
Comedonal is the mildest type of acne and doesn’t cause painful swelling or inflammation in most cases. It usually manifests as blackheads or whiteheads on the skin. Blackheads occur when dirt and germs under the skin’s pores cause the skin to appear dark. Males going through puberty, as well as young adults, will experience some form of comedonal acne in their lives. It also may occur because of allergic reactions to skin or hair products, but most acne lesions, such as whiteheads and blackheads, occur because of a hard blockage of excess sebum in skin pores.
Acne isn’t just a problem for teens. According to studies, those pesky zits and pimples can pop up at any age. Whether it’s your diet, environment or stress that’s to blame, you don’t have to suffer helplessly. To get the skinny on acne, we talked to board-certified dermatologist Cynthia Bailey, M.D., president and CEO of Advanced Skin Care and Dermatology Physicians, Inc. and founder of DrBaileySkinCare.com. Here, she shares her best tips on how to choose the right acne cleanser for you, as well as how to use it to get the best results.

Spot treatments are designed to give problem pimples a mega-dose of concentrated benzoyl peroxide — in a couple of regimens, like the Proactiv Teen Kit, the spot treatment had nearly three times the benzoyl peroxide as its all-over treatment. The logic: If benzoyl peroxide can be irritating to the skin in high concentrations, limiting its intensity to just the pimple itself could save the rest of your healthy skin.
For example, if you have acne on dry skin, you need something gentle enough to cleanse and exfoliate but not dehydrate, like a Neutrogena cleanser. If you have oily skin, you’re looking to exfoliate and combat oil production with a product like Cetaphil. If you have combination skin, you need something that can treat your unique skin and balance it out, like Exposed Skin Care.

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.[41] 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).[42][43]
If your acne is severe, painful, or refusing to get lost, you may just be beyond what an over-the-counter treatment can do. Not only can a professional set you up with the really powerful stuff, but also Fitz Patrick explains that “working closely with an aesthetician or dermatologist means you can keep tweaking a routine to make it work best for you.”
Complementary therapies have been investigated for treating people with acne.[150] Low-quality evidence suggests topical application of tea tree oil or bee venom may reduce the total number of skin lesions in those with acne.[150] Tea tree oil is thought to be approximately as effective as benzoyl peroxide or salicylic acid, but has been associated with allergic contact dermatitis.[1] Proposed mechanisms for tea tree oil's anti-acne effects include antibacterial action against P. acnes, and anti-inflammatory properties.[65] Numerous other plant-derived therapies have been observed to have positive effects against acne (e.g., basil oil and oligosaccharides from seaweed); however, few studies have been performed, and most have been of lower methodological quality.[151] There is a lack of high-quality evidence for the use of acupuncture, herbal medicine, or cupping therapy for acne.[150]
Salicylic Acid – One of the most common topical ingredients you can find over-the-counter, salicylic acid is generally used to reduce the appearance of acne, by reducing swelling and redness. Also known as a beta-hydroxy acid, it exfoliates your skin4 and unclogs your pores, too, but it is quite strong. You’ll only be able to find this in strengths around 2%, but it can still dry and irritate your skin, especially if yours is sensitive. The safest way to use this ingredient is according to the directions!
The Daily Skin Clearing Treatment is an all-over 2.5 percent benzoyl peroxide cream that also touts calming bisabolol and allantoin to alleviate the dryness and irritation that can crop up mid-treatment. Anyone frustrated with oil-slick skin will also love this part of the regimen — it creates a satin mattifying effect, instantly transforming shininess into a glow.
Salicylic acid and azelaic acid. Azelaic acid is a naturally occurring acid found in whole-grain cereals and animal products. It has antibacterial properties. A 20 percent azelaic acid cream seems to be as effective as many conventional acne treatments when used twice a day for at least four weeks. It's even more effective when used in combination with erythromycin. Prescription azelaic acid (Azelex, Finacea) is an option during pregnancy and while breast-feeding. Side effects include skin discoloration and minor skin irritation.
The second reason is that alcohol is super at removing oil from the skin. The problem lies in the fact that alcohol removes too much of this oil. This can cause your complexion to become raw and irritated. Also, your glands will react to the sudden lack of oil/sebum by trying to generate more and more. As noted before, this will result in a viscious cycle that will be disastrous for the well-being of your skin.
Clean your face really well using a mild face cleanser and gently pat dry. Let your skin further air dry and don’t put anything else on it. Don’t put anything else on your face like moisturizer, serum, toner, etc. After a half hour, carefully check your cheeks, chin, forehead and nose, with a hand mirror, for any shine. Also, check if your skin feels tight when you smile or make exaggerated facial expressions.
