There has been a long-observed link between higher stress levels and the incidence of breakouts, and studies have shown that stress can worsen acne’s frequency and severity. Sebaceous glands contain receptors for stress hormones, making them upregulated and kicking sebum production into overdrive. Unfortunately, those with stress sometimes fall victim to a vicious acne cycle. Anxious types have a tendency to pick their skin and pop pimples under stress. This bad habit can exacerbate blemishes by pushing the buildup deeper into the pore, inducing cellular damage, rupturing cellular walls, and spreading bacteria. In extreme cases, sometimes people become so worried or embarrassed about their skin that they compulsively pick at every little thing that shows up. This condition is called acne excoriee, and can turn mild acne into severe scars.

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).


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.[26][27][28] 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.[26]
Genetics play a big part in who gets acne and how severely, but each blemish can be blamed on some combination of sebum production, a bacteria called Propionibacterium acnes (P. acnes), plugged follicles, and inflammation. Finding a good treatment is really about finding the right combination of ingredients to troubleshoot each of those issues. Some factors that might worsen acne include hormones, certain medications, diet and stress.
This inflammatory cascade typically leads to the formation of inflammatory acne lesions, including papules, infected pustules, or nodules.[1] If the inflammatory reaction is severe, the follicle can break into the deeper layers of the dermis and subcutaneous tissue and cause the formation of deep nodules.[1][66][67] Involvement of AP-1 in the aforementioned inflammatory cascade leads to activation of matrix metalloproteinases, which contribute to local tissue destruction and scar formation.[45]

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]
Temporary skin fillers have been used for years for acne scar treatment, but a permanent dermal filler was approved for use by the FDA only recently. Designed to remove moderate to severe acne scarring, Bellafill is made up of 80 percent collagen to replace lost volume and 20 percent polymethylmethacrylate, which helps your body heal by boosting protein production.
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.[146] 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).[146]
Look for a mattress that allows enough space so that your partner can move around without impacting you or consider a mattress made for two sleepers like the Sleep Number bed.[1] This bed allows each person to choose their own firmness level. It also minimizes any disturbances their partner might feel. A foam mattress like the kind featured in advertisements where someone jumps on a bed with an unspilled glass of wine will help minimize the impact of your partner’s movements.[2]

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]


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.

Atrophic acne scars have lost collagen from the healing response and are the most common type of acne scar (account for approximately 75% of all acne scars).[32][33] They may be further classified as ice-pick scars, boxcar scars, and rolling scars.[31] Ice-pick scars are narrow (less than 2 mm across), deep scars that extend into the dermis.[32] Boxcar scars are round or ovoid indented scars with sharp borders and vary in size from 1.5–4 mm across.[32] Rolling scars are wider than icepick and boxcar scars (4–5 mm across) and have a wave-like pattern of depth in the skin.[32]
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][47] 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][36][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.[36] 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.[47] 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.[36][107]

The earliest pathologic change is the formation of a plug (a microcomedone), which is driven primarily by excessive growth, reproduction, and accumulation of skin cells in the hair follicle.[1] In normal skin, the skin cells that have died come up to the surface and exit the pore of the hair follicle.[10] However, increased production of oily sebum in those with acne causes the dead skin cells to stick together.[10] The accumulation of dead skin cell debris and oily sebum blocks the pore of the hair follicle, thus forming the microcomedone.[10] This is further exacerbated by the biofilm created by C. acnes within the hair follicle.[45] If the microcomedone is superficial within the hair follicle, the skin pigment melanin is exposed to air, resulting in its oxidation and dark appearance (known as a blackhead or open comedo).[1][10][20] In contrast, if the microcomedone occurs deep within the hair follicle, this causes the formation of a whitehead (known as a closed comedo).[1][10]


Hypertrophic scars are uncommon, and are characterized by increased collagen content after the abnormal healing response.[32] They are described as firm and raised from the skin.[32][34] Hypertrophic scars remain within the original margins of the wound, whereas keloid scars can form scar tissue outside of these borders.[32] Keloid scars from acne occur more often in men and people with darker skin, and usually occur on the trunk of the body.[32]

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]

Clascoterone is a topical antiandrogen which has demonstrated effectiveness in the treatment of acne in both males and females and is currently in the late stages of clinical development.[120][121][122][123] It has shown no systemic absorption or associated antiandrogenic side effects.[122][123][124] In a direct head-to-head comparison, clascoterone showed greater effectiveness than topical isotretinoin.[122][123][124] 5α-Reductase inhibitors such as finasteride and dutasteride may be useful for the treatment of acne in both males and females, but have not been thoroughly evaluated for this purpose.[1][125][126][127] In addition, the high risk of birth defects with 5α-reductase inhibitors limits their use in women.[1][126] However, 5α-reductase inhibitors can be combined with birth control pills to prevent pregnancy, and are frequently used to treat excessive hair in women.[125] There is no evidence as of 2010 to support the use of cimetidine or ketoconazole in the treatment of acne.[128]

Castor oil has anti-inflammatory and antibacterial properties that can speed up healing, making it ideal for breakout-prone skin. Though I recommend using it in very small amounts with jojoba oil, hemp seed oil or coconut oil, along with one of the essential oils above, it’s high in unsaturated fatty acids, vitamin E, proteins and minerals, which can help reduce acne-causing bacteria and inflammation associated with breakouts. It can even help heal scars caused by acne.
Exercise regularly. Exercising does a number of things to help reduce your acne. It releases endorphins which lower stress levels and therefore reduce oil-production and also makes you sweat which cleans out dead skin cells. Try exercising on a daily basis for a minimum of thirty minutes to help reduce your acne not only on your face, but also on your chest, shoulders, and back; which is where the term "bacne" comes from.
Your skin is your largest organ, and it does a lot more than simply prevent you from spilling out all over the place. Skin cells are constantly replacing themselves, making a journey from the inner edge of your epidermis (your skin's outermost layer) to the outside of your skin. As a skin cell ages and approaches the skin's surface, the dying cell flattens out. Once on the surface, it joins countless other dead skin cells and forms a protective layer that helps protect you from bacteria and viruses.

Another vice that can lead to worsened acne is alcohol. As we mentioned, your diet and acne are related. One glass of wine won’t trigger a breakout – even contains beneficial antioxidants! – but excessive alcohol consumption can alter your hormone levels. Making matters worse, many people drink due to stress, which also affects acne-inducing hormones. Alcohol impairs the liver’s ability to purify toxins, and if the liver is compromised, toxins are expelled through different channels such as your skin. It’s full of that sugar we just warned you about and weakens your immune system, which inhibits your body’s natural ability to fight off P. acnes bacteria. If you pass out after a night of drinking without washing your face, your pores are more likely to become clogged and create pimples. Almost everyone enjoys indulging in a drink every now and then, but moderation here is key.

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.”
There are some foods that must be avoided for removing acne. These foods are milk, chocolates, sweets, desserts, cakes, fat and oil. You need to eat vitamins and minerals rich foods to get rid of acne. The examples of vitamins are vitamin A and C. These vitamins mainly found in orange and carrots. There is some other food such as eating organic foods. These foods are not harmful to acne.
The costs and social impact of acne are substantial. In the United States, acne vulgaris is responsible for more than 5 million doctor visits and costs over US$2.5 billion each year in direct costs.[13] Similarly, acne vulgaris is responsible for 3.5 million doctor visits each year in the United Kingdom.[20] Sales for the top ten leading acne treatment brands in the US in 2015, have been reported as amounting to $352 million.[176]
Toothpaste is a good option if you have a mammoth pimple that you want to take care of quickly. It is effective because it contains silica, which is the same substance that can be found in bags of beef jerky to keep moisture out. As such, toothpaste has been know to dry out and reduce the size of pimples over night. Simply apply some to the affected area before sleep and wash it off in the morning.
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.
A study conducted by the Department of Dermatology at the University of Freiburg in Germany reports that using frankincense and five other plant extracts for antimicrobial effects on bacteria and yeast relating to the skin proved effective. The study concluded that their antimicrobial effects were powerful enough to be used as a topical treatment of some skin disorders, including acne and eczema. (19) 
Whereas acne vulgaris clogs pores from the bottom up, acne inversa (or hidradenitis suppurativa) is a form of acne that clogs pores from the top down. It’s caused by excessively rapid skin growth, occluding the mouth of pores with shed skin cells. When the pores are blocked and clogged, they become inflamed and can create pimples and acne lesions. This form of acne is usually observed in intertriginous skin, where two skin areas may touch or rub together. Induced or aggravated by heat, moisture, maceration, friction and lack of air circulation. Examples of these areas include underarms, folds of the breasts, and between buttocks cheeks.
Does your infant have more pimples than an eighth-grader? Just when she seems ready for her close-up — head rounding out nicely, eyes less puffy and squinty — baby acne might be next. This pimply preview of puberty is incredibly common, usually beginning at 2 to 3 weeks of age and affecting about 40 percent of all newborns. Fortunately it’s temporary, and it doesn’t bother your baby a bit. Here’s what to do in the meantime.
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.
Blemishes on your new baby's face aren't necessarily acne, however. Tiny white bumps that are there at birth and disappear within a few weeks are called milia, and they're not related to acne. If the irritation looks more rashy or scaly than pimply, or it appears elsewhere on your baby's body, he may have another condition, such as cradle cap or eczema.
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.

The birth control pill is another option for women suffering hormonal acne. Four types of birth control pills have been approved by the FDA for use as acne treatment, and all four are combination pills that contain both estrogen and progesterone. Talk to your doctor about how to get rid of acne using birth control and keep in mind that Ortho Tri-cyclen, Estrostep YAZ and Beyaz are the only four brands specifically FDA approved as acne remedies.
That’s good news because the British Medical Journal reports that acne affects more than 80 percent of teenagers and continues in adult life in 3 percent of men and 12 percent of women. In fact, it seems to be increasing, which could be due to autoimmune disease, leaky gut syndrome or allergies, for example. Hormonal factors may play a role in breakouts as well. (1)
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]

Eat healthily. Foods that are highly processed and contain a lot of oils greatly increase the amount of acne on your body. Getting the proper amount of nutrients from whole grains, fruits, vegetables, and protein help your skin to regenerate faster and limit unnecessary oil production. When at all possible, avoid foods that are processed or contain a lot of sugar (think junk foods).[11]

The main hormonal driver of oily sebum production in the skin is dihydrotestosterone.[1] Another androgenic hormone responsible for increased sebaceous gland activity is DHEA-S. Higher amounts of DHEA-S are secreted during adrenarche (a stage of puberty), and this leads to an increase in sebum production. In a sebum-rich skin environment, the naturally occurring and largely commensal skin bacterium C. acnes readily grows and can cause inflammation within and around the follicle due to activation of the innate immune system.[10] C. acnes triggers skin inflammation in acne by increasing the production of several pro-inflammatory chemical signals (such as IL-1α, IL-8, TNF-α, and LTB4); IL-1α is known to be essential to comedo formation.[45]
