Why Acne Persists for Years in Some People
Many people think acne ends after the teenage years, but for some, it sticks around into adulthood and even lasts for years. This happens because adult acne has different triggers than teen breakouts, often tied to ongoing changes in the body and daily habits.
Hormones are a big reason acne does not go away. In adults, especially women, shifts in hormones like androgens can make oil glands produce too much sebum, which clogs pores and leads to pimples[1][2][3]. These hormones can fluctuate with menstrual cycles, pregnancy, menopause, or starting and stopping birth control[2][4]. Conditions like polycystic ovary syndrome, or PCOS, raise androgen levels, causing stubborn jawline acne that resists simple treatments[1][2][4]. Other health issues, such as hypothyroidism or adrenal problems, can also boost these hormones and keep breakouts coming[2].
Stress and lack of sleep make things worse by raising cortisol, a hormone that ramps up oil production and inflammation[1][3]. Unlike teen skin, which is oily from puberty surges, adult skin is often drier and more sensitive, so it reacts strongly to these pressures[3][4].
Diet plays a role too. Foods high in dairy or sugar, like sodas, pastries, and whey protein, spike insulin and androgens, worsening sebum and flares[1][2]. Lifestyle choices, such as poor sleep or chronic stress, add to the cycle in adults more than in teens[1][3].
Using the wrong skincare habits keeps acne alive. Over-washing strips the skin barrier, prompting more oil to fight back and trap bacteria[1][4][5]. Heavy makeup or too many products irritate sensitive adult skin, leading to ongoing inflammation[3][4][5]. Breakouts in adults often hit the jawline and lower face, not just the forehead like in teens, signaling these deeper issues[1][3].
