The cause of adult acne has not been identified as yet, but there are theories. One of them is that teens and adults share on common nemesis, albeit at different levels – stress. Stress causes internal changes that temporarily disturb hormonal equilibrium, and may just be responsible for pimples that seem to pop up at the worst possible time.

Treatment and damage control for adult acne does not differ drastically from that for teen acne. But considering the ambiguity surrounding the causes, care and prevention are highly personalized issues. Should one, for instance, note that they break out with a rash of zits while reading the latest Stephen King novel or after the monthly argument with their spouse, some changes in reading habits and lifestyle may very well be in order. Adult females are far more given to the use of elaborate and inadvisable makeup regimens than teenagers are, and males are catching up.

While treating adult acne, bear in mind that adult skin is far less resilient and elastic than teen skin. Avoid harsh soaps and 'skin-stripping' agents and stick to mild cleaners and generally follow the care and prevention regimen prescribed for teen acne with an added precaution. In adults, there is a reduced ability of skin to re-moisturize naturally after being subjected to the abrasive and dehydrating effects of a compound like benzoyl peroxide. The use of such a compound must necessarily be followed by the application of a hypoallergenic, no-oily moisturizer – preferably made of organic extracts – to reestablish the skin's natural moisture content.

Adult Acne can be frustrating and embarrassing, but it is treatable. It is advised to contact a dermatologist for chronic adult acne.
