Adult acne is usually defined as acne that affects people over the age of 25.
In about 1/2 of cases, acne ends after adolescence (around 18 – 20). For the other 1/2, it continues into adulthood. For a minority of people, particularly women, acne can subside after adolescence and then make a resurgence in adulthood.
Adult Acne in Men: Exactly why acne continues in men is not fully understood, but normally it is as simple as “it hasn’t gone away yet.” That means, just like what caused acne in the first place, it is a potential combination of:
Treatment of Adult Men: Treating acne with a proper benzoyl peroxide regimen can keep the vast majority of men clear. However, in some cases of severe, widespread (particularly if on large areas of the body), and scarring acne, isotretinoin is an option that can be carefully and soberly considered.
Adult Acne in Women: While girls as a whole have less acne than boys, this balance flips in adulthood, with more women struggling with adult acne after the age of 25. This is thought to be because of the fluctuating hormones during the menstrual cycle, but may also be due to:
Treatment of Adult Women: Treating acne with a proper benzoyl peroxide regimen can keep the vast majority of women clear, even through the hormonal roller coaster a menstrual cycle entails. However, when blood tests show a hormonal imbalance, particularly when levels of androgens (male hormones) are overly elevated, hormonal treatment, including oral contraceptives (the birth control pill) and/or anti-androgens, can be the treatment of choice. In some cases of very severe and scarring acne, a last resort option is isotretinoin (Accutane®), an oral medication that comes with many side effects–some of which can be lifelong–but can clear acne in extreme cases.
Isotretinoin is the #1 birth defect-causing medication on the market. Consider it only if under the supervision of an experienced physician, and if it is taken, always use at least two (2) forms of responsible and dependable birth control. And as with any medication that permanently changes the body, have your eyes open to potentially long-term side effects.
