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.
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.

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.
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) 
Globally, acne affects approximately 650 million people, or about 9.4% of the population, as of 2010.[158] 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][159] 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%).[158] In those over 40 years old, 1% of males and 5% of females still have problems.[20]
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]

“Sometimes I see people try over-the-counter products just for a couple of weeks, they get frustrated, they say it’s not working, and they discontinue them,” Arthur says. “But it really does take a while to see the effectiveness. So unless you’re having a problem with the medication, like it’s causing severe irritation or dryness, it’s recommended to give it at least 2-3 months before switching to something else.”

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]
To many parents’ dismay, their beautiful newborn’s face breaks out with red bumps at around 3 to 4 weeks of age. This is called baby acne. It tends to occur at about the same age as the baby’s peak gas production and fussiness. How attractive! (This all coincides with parents’ maximum sleep deprivation.) Parents are often quite concerned both about how these bumps look and about their significance.
Benzoyl peroxide is an antibacterial ingredient, and it’s very effective at killing the P. acnes bacteria that causes breakouts. But benzoyl isn’t without its downsides. The leave-on creams and cleansing treatments can dry out sensitive skin types and bleach clothing if you aren’t careful. Board-certified dermatologist Eric Meinhardt, M.D., previously told SELF that it's best to stick to formulations that have no more than 2 percent of benzoyl peroxide listed on the active ingredients chart; stronger concentrations are harder on your skin without being any tougher on bacteria.
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]

Oh, hello old friend. Salicylic acid is the go-to fix for pimply preteens. And cruising through the aisles at the drugstore, you’ll find it as the active ingredient on the majority of products labeled “acne wash” or “spot treatment.” Salicylic acid is a beta-hydroxy acid that works by dissolving excess oil and gently exfoliating away dead skin cells. Salicylic also has anti-inflammatory properties to help with inflamed cystic breakouts that can occur when blockages deep in the hair follicles rupture beneath the skin. It’s best to apply this ingredient as a toner, moisturizer, or leave-on spot treatment instead of a face wash to give it time to do its work. And keep in mind, salicylic acid can dry out the skin if over-applied, so maybe choose only one product with the ingredient to use every day.

Alternative and integrative medicine approaches used in the treatment of acne include fish oil, brewer's yeast, probiotics, oral zinc and topical tea tree oil. More research is needed to establish the potential effectiveness and long-term safety of these and other integrative approaches, such as biofeedback and traditional Chinese medicine. Talk with your doctor about the pros and cons of specific treatments before you try them.
