Genetics is thought to be the primary cause of acne in 80% of cases.[2] The role of diet and cigarette smoking is unclear, and neither cleanliness nor exposure to sunlight appear to play a part.[2][13][14] In both sexes, hormones called androgens appear to be part of the underlying mechanism, by causing increased production of sebum.[5] Another frequent factor is excessive growth of the bacterium Cutibacterium acnes, which is normally present on the skin.[15]
Another once-daily gel your dermatologist might prescribe for acne is Aczone 7.5 percent. The active ingredient, dapsone, is both antimicrobial and anti-inflammatory, and it’s proven to help with blackheads, whiteheads, and deeper painful pimples. Oftentimes, Aczone is used alongside other acne treatments. And like many of those other remedies, Aczone can cause skin to dry out.

Hormonal acne is exactly what it sounds like: breakouts that are tied to fluctuations in hormones. If your skin flares up at the same time each month, tends to occur in the same spot (chin, cheeks, jawline), and is characterized by pimples that are deep and cystic, your acne might be hormonal. Hormonal acne is usually due to a sensitivity to androgens, which are a specific type of hormone. With respect to acne, the androgen in charge is testosterone. Testosterone (and estrogen) are produced and needed by both sexes, but women are sensitive to extraneous amounts since it’s unnecessary for their typical functioning. The excess androgen has to go somewhere, and is usually purged via the skin’s androgen receptor cells which creates breakouts. While testosterone remains in the bloodstream, it increases sebum production and can make breakouts worse.
Decreased levels of retinoic acid in the skin may contribute to comedo formation. To address this deficiency, methods to increase the skin's production of retinoid acid are being explored.[10] A vaccine against inflammatory acne has shown promising results in mice and humans.[50][181] Some have voiced concerns about creating a vaccine designed to neutralize a stable community of normal skin bacteria that is known to protect the skin from colonization by more harmful microorganisms.[182]
The three-piece set doesn’t come with a sun protection treatment, but Paula’s Choice has one in the line, the Clear Ultra-Light Daily Fluid SPF 30+. “Sun protection is really important, especially with acneic skin,” says Townsend. “In many cases, stronger acne products can make the skin photosensitive to the sun.” This isn’t your normal gloppy white sunscreen. Its fluid formula slips over tender skin, doesn’t need a ton of rubbing in, and also leaves a mattifying finish.

Cystic acne is the most severe form of acne vulgaris and can be caused by a variety of factors. This type of acne sees painful lesions develop deep within the skin, which could result in permanent scarring or hyperpigmentation. Cystic acne is easily diagnosed due it its pronounced, inflamed lesions. However, you should consult a dermatologist to rule out other skin conditions which might mimic acne such as rosacea, psoriasis or perioral dermatitis.

For UVA protection, a sunscreen with a high UVA protection of PA+++ or higher of PA++++ as recommended, especially to treat PIE. PPD is the UVA equivalent of SPF; use a sunscreen with a minimum of PPD20. The PA+ system has a + that corresponds to a tier of PPD protection. Of note, different countries use different PA systems. Japan and Taiwan changed their PA system to a 4+ tier system while Korea uses a 3+ tier system.


How to Handle It: Your best bet is benzoyl peroxide. "Benzoyl peroxide can kill acne-causing bacteria and reduce inflammation," says Zeichner. Try a cream like the La Roche-Posay Effaclar Duo Dual-Action Acne Treatment ($37), which also exfoliates with lipo-hydroxy acid. Be aware that it can seriously dry out skin so moisturize well after you use it.
Topical and oral preparations of nicotinamide (the amide form of vitamin B3) have been suggested as alternative medical treatments.[134] It is thought to improve acne due to its anti-inflammatory properties, its ability to suppress sebum production, and by promoting wound healing.[134] Topical and oral preparations of zinc have similarly been proposed as effective treatments for acne; evidence to support their use for this purpose is limited.[135] The purported efficacy of zinc is attributed to its capacity to reduce inflammation and sebum production, and inhibit C. acnes.[135] Antihistamines may improve symptoms among those already taking isotretinoin due to their anti-inflammatory properties and their ability to suppress sebum production.[136]

Shower twice a day. Take a shower or bath in the morning and at night. Alternatively, take a shower in the morning and then again after physical activity, like exercise, or sweating. Wash your entire body with a mild cleanser and use shampoos that limit oil production in your hair. Be sure to always shower after exercising to remove the dead skin cells your body has sloughed off through sweating.


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.

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]

The use of antimicrobial peptides against C. acnes is under investigation as a treatment for acne to overcoming antibiotic resistance.[10] In 2007, the first genome sequencing of a C. acnes bacteriophage (PA6) was reported. The authors proposed applying this research toward development of bacteriophage therapy as an acne treatment in order to overcome the problems associated with long-term antibiotic therapy such as bacterial resistance.[179] Oral and topical probiotics are also being evaluated as treatments for acne.[180] Probiotics have been hypothesized to have therapeutic effects for those affected by acne due to their ability to decrease skin inflammation and improve skin moisture by increasing the skin's ceramide content.[180] As of 2014, studies examining the effects of probiotics on acne in humans were limited.[180]
A nodule is an abnormal tissue growth which can either develop just below the skin or anywhere within the skin’s three layers (the epidermis, dermis, and subcutaneous tissue). Nodules commonly form in regions such as the face, neck, armpits, and groin, although they can also develop on internal organs such as the lungs, thyroid, and lymph nodes. They create solid, raised lumps that are more than 1 to 2 centimeters in diameter, with the potential to reach up to the size of a hazelnut. Nodules are hard and firm to the touch, unlike cysts whose pus makes them softer to the touch. This type of severe acne should be consulted by a doctor, as it might be indicative of a more serious condition.
Risk factors for the development of acne, other than genetics, have not been conclusively identified. Possible secondary contributors include hormones, infections, diet and stress. Studies investigating the impact of smoking on the incidence and severity of acne have been inconclusive.[2][38][39] Sunlight and cleanliness are not associated with acne.[14]

What's Going On: If it's big, red, and painful, you're probably experiencing cystic acne, one of the more severe types. "Cystic pimples are caused by genetics and hormonal stimulation of oil glands," says Zeichner. Not only are they large, but they're also notoriously tough to treat. They often recur in the same place, because even if you manage to get rid of one, it can keep filling up with oil again and again, like an immortal pimple.

If one partner likes bringing devices to bed and the other partner doesn’t, there’s very little compromise to be found. Science is pretty unanimous on the fact that screens can cause harm to a healthy sleeper. Both partners should agree on a time to keep technology out of the bedroom or turn screens off. This will prevent both partners from having their sleep interrupted and can help you power down after a long day.

It's a common misconception that those with oily skin shouldn't moisturize. Be sure you're treating your entire face to a full routine and not solely relying on spot treatments to battle your breakouts. If your acne comes with a side of oil, this is your best bet for a daily moisturizer. It contains panadoxine, a vitamin B6 derivative that improves skin’s overall healthy balance by visually minimizing pore size and shine.
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]
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.
