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]
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.

In the simplest sense, acne is caused when pores containing hair follicles and sebaceous (oil) glands become clogged. The sebaceous gland is responsible for producing sebum, an oily substance necessary for skin to stay hydrated and soft. However, too much sebum can plug the opening at the top of the pore, trapping a buildup of oil, dead skin cells, and bacteria leading to acne lesions.
Microneedling is a procedure in which an instrument with multiple rows of tiny needles is rolled over the skin to elicit a wound healing response and stimulate collagen production to reduce the appearance of atrophic acne scars in people with darker skin color.[140] Notable adverse effects of microneedling include postinflammatory hyperpigmentation and tram track scarring (described as discrete slightly raised scars in a linear distribution similar to a tram track). The latter is thought to be primarily attributable to improper technique by the practitioner, including the use of excessive pressure or inappropriately large needles.[140][147]
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.

Some people swear by the disinfecting power of tea tree oil for acne treatment. It can be applied either full strength or slightly diluted with water directly onto pimples. Use a small amount on a clean cotton swab or cotton pad and dab on the affected areas immediately after cleansing. Because tea tree oil can be drying, you might choose to use both tea tree oil and coconut oil for acne as part of your clear skin regimen.
Not only can the sun prolong PIE appearance, it can lead to premature aging including sun spots, fine lines, and wrinkles. UV damage is DNA damage. Sunscreen is an anti-aging must for all ages young and old--preventing future skin cancer. It is the fountain of youth in a bottle. Prevention is better than treatment. There is no such thing as safe tanning, as tanning is the result of sun damage.
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]

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.
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.
The severity of acne vulgaris (Gr. ἀκµή, "point" + L. vulgaris, "common")[24] can be classified as mild, moderate, or severe as this helps to determine an appropriate treatment regimen.[20] There is no universally accepted scale for grading acne severity.[15] Mild acne is classically defined by the presence of clogged skin follicles (known as comedones) limited to the face with occasional inflammatory lesions.[20] Moderate severity acne is said to occur when a higher number of inflammatory papules and pustules occur on the face compared to mild cases of acne and are found on the trunk of the body.[20] Severe acne is said to occur when nodules (the painful 'bumps' lying under the skin) are the characteristic facial lesions and involvement of the trunk is extensive.[20][25]
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 side effects depend on the type of treatment you use. Generally, for topical, over-the-counter creams, you can watch out for stinging, redness, irritation and peeling — these side effects usually don’t go any deeper than the skin. Others, like oral antibiotics or hormonal medications, could come with new sets of complications, so we suggest talking to your doctor before pursuing the treatment.


Acne medications work by reducing oil production, speeding up skin cell turnover, fighting bacterial infection or reducing inflammation — which helps prevent scarring. With most prescription acne drugs, you may not see results for four to eight weeks, and your skin may get worse before it gets better. It can take many months or years for your acne to clear up completely.
