Why do adults get acne if they never got it when they were kids?

Best hypothesis is... ...hormones. According to my studies, most adult onset acne is usually caused by some kind of hormonal change (mostly in women, but can occur in men). From "Skin Care, Beyond the Basics" by Mark Lees, "Hormones, specifically male hormones, or androgens, are the mechanism that cause stimulation of the sebaceous glands, which, in turn, produce more sebum (oil).

This sebum causes inflammation in the follicles, causing the cell buildup and providing a source of fatty acids, which is the food of the P. Acnes bacteria. " Testosterone can also cause this to occur.

There are also environmental factors that can affect acne flareups. These are heat and humidity, excessive sun exposure, stress, cosmetics, picking, and overcleaning. Heat and humidity - heat and humidity cause the skin to swell, which may put enough pressure on the follicle to cause a flare-up.

Excessive sun exposure - too much sun can cause cell buildup, which clogs follicles. Stress - stress triggers hormones. Hormones, in turn, can trigger the production of oil, hence, the "date night" pimple.8) Cosmetics - some cosmetics are pore-clogging and have ingredients that cause inflammation.

This can trigger breakouts. Picking - yeah, it sounds gross, but a lot of people pick at their pimples. This can trigger additional inflammation and possibly infect the lesion.

Overcleaning - acne can be aggravated by too much cleaning. Sources: Skin Care, Beyond the Basics by Mark Lees (Thompson Learning) .

There are different causes for Acne There are many forms of Acne, and only one is related to puberty:Acne is a group of skin rashes that have different causes. Acne vulgaris - most commonly experienced around puberty, typically of the face and shoulders/chest Acne rosacea - a red rash predominantly on the face Acne keloidalis nuchae (Pseudofolliculitis nuchae) - a rash caused by shaving Acne conglobata (dradenitis suppurativa) - chronic abscesses or boils of sweat glands and hair follicles; in the underarms, groin and buttocks, and under the breasts in women Acne cosmetica - acne caused by cosmetics Acne fulminans - an extreme form of acne conglobata Acne medicamentosa - acne caused by starting or stopping a medicine Baby acne - a rash seen on the cheeks, chin, and forehead of infants According to Wikipedia:"The condition is most common in puberty, especially among Western societies most likely due to a higher genetic predisposition. It is considered an abnormal response to normal levels of the male hormone testosterone.

The response for most people diminishes over time and acne thus tends to disappear, or at least decrease, after one reaches their early twenties. There is, however, no way to predict how long it will take for it to disappear entirely, and some individuals will continue to suffer from acne decades later, into their thirties and forties and even beyond. Acne affects a large percentage of humans at some stage in life."Other versions of Acne affect babies (skin rash), women (cosmetics), or men (shaving), and usually is caused by pores getting blocked.

So, some might have evaded the Acne Vulgaris succesfully, but then getting affected after all due to cosmetics or shaving. Sources: My knowledge .
