Acne that never fully clears up often stems from ongoing triggers like hormonal imbalances, genetics, and lifestyle factors that keep pores clogged and inflammation active, even after treatments seem to work at first. Many people deal with this frustrating cycle where breakouts return, leaving skin bumpy or scarred over time.
One big reason is hormones. Androgens, which are male hormones present in everyone, ramp up oil production in sebaceous glands. When these hormones get out of balance, glands make too much sebum, mixing with dead skin cells to block hair follicles. This leads to blackheads, pimples, and cysts. In women, this shows up as jawline or chin acne tied to menstrual cycles, pregnancy, menopause, or conditions like polycystic ovary syndrome (PCOS), where androgen levels stay high.[1][2] Stress adds to it by releasing cortisol, which boosts oil and worsens inflammation.[2][5]
Genetics play a strong role too. If your family has a history of acne, you are more likely to have overactive glands or skin that clogs easily. This makes acne start in the teen years and stick around into adulthood for some people.[3][4][6]
Bacteria and inflammation keep things going. Cutibacterium acnes, a common skin bacteria, thrives in clogged pores and sparks swelling. An overreactive immune system can turn small blockages into deep, painful nodules that scar.[1][3][4]
Lifestyle and environment matter as well. Diet high in certain foods, gut issues, medications, or even friction from tight clothing can flare things up. Pore-clogging products or harsh skincare might irritate skin further, preventing clear-up.[4][5][7] Changes in climate or emotional stress can make it worse too.[3]
In adults, this persistent type often resists basic creams or washes because the root causes like hormones or genetics keep firing. Without tackling them, acne cycles back, especially with painful or scarring spots.[1][2][4]
