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.
Dermabrasion is an effective therapeutic procedure for reducing the appearance of superficial atrophic scars of the boxcar and rolling varieties.[32] Ice-pick scars do not respond well to treatment with dermabrasion due to their depth.[32] The procedure is painful and has many potential side effects such as skin sensitivity to sunlight, redness, and decreased pigmentation of the skin.[32] Dermabrasion has fallen out of favor with the introduction of laser resurfacing.[32] Unlike dermabrasion, there is no evidence that microdermabrasion is an effective treatment for acne.[8]
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.

Hormonal treatments for acne such as combined birth control pills and antiandrogens may be considered a first-line therapy for acne under a number of circumstances, including when contraception is desired, when known or suspected hyperandrogenism is present, when acne occurs in adulthood, when acne flares premenstrually, and when symptoms of significant sebum production (seborrhea) are co-present.[128] Hormone therapy is effective for acne even in women with normal androgen levels.[128]
In general, it is recommended that people with acne do not wash affected skin more than twice daily.[15] For people with acne and sensitive skin, a fragrance free moisturizer may be used to reduce irritation. Skin irritation from acne medications typically peaks at two weeks after onset of use and tends to improve with continued use.[15] Cosmetic products that specifically say "non-comedogenic", "oil-free", and "won't clog pores" are recommended.[15]
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]
Isotretinoin is an oral retinoid that is very effective for severe nodular acne, and moderate acne that is stubborn to other treatments.[1][20] 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.[20] About 20% of patients require a second course.[20] 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][20] Isotretinoin is superior to antibiotics or placebo in reducing acne lesions.[17] The frequency of adverse events was about twice as high with isotretinoin, although these were mostly dryness-related events.[17] No increased risk of suicide or depression was conclusively found.[17] Isotretinoin use in women of childbearing age is regulated due to its known harmful effects in pregnancy.[20] 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.[20] 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]

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]

Topical treatments on their own may not be enough to give you clear skin, especially in those with complicated, inflammatory cystic acne. There are several acne medication options approved for use by the FDA, but which one is best for you is a question for your dermatologist and/or general practitioner. Baldwin says if you have insurance and you have acne, a prescription may be the best step because "it makes no sense to try to handle the condition yourself or to use over the counter products that are always less effective than prescriptions meds." Here are a few of the acne medications you'll want to ask about:
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.

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.
