Chin and jawline acne is often caused by fluctuations in hormones , which means a disruption with your endocrine system. It's typically a result of excess androgens , which overstimulate the oil glands and clog pores.
Chin pimples are a common occurrence that can happen throughout adulthood, especially in females. Hormones are typically responsible for stimulating the production of extra oil on the chin, which can trap skin cells or dirt and bacteria, which causes pimples to form.
"Stress acne, unlike your regular breakouts, usually occurs on the oiliest parts of your face—your forehead, nose, and chin areas," says Shereene Idriss, M.D., a cosmetic dermatologist at New York City's Union Square Laser Dermatology.
What does hormonal acne look like? Whiteheads, blackheads, papules, pustules, cysts and nodules are all common hormonal acne symptoms. Normally, whiteheads and blackheads do not cause pain, inflammation or swelling, but if they do, then they are most likely forming into cysts and pustules.
Hormonal acne happens because of hormone fluctuations, especially testosterone. A rise in testosterone may stimulate the excessive sebum production from the sebaceous glands. When this sebum combines with dirt, bacteria, and dead skin cells, it results in clogged pores and acne.
Sudden acne breakouts can be because of numerous reasons, including hormonal changes or hormonal imbalance, an unhealthy diet including lots of deep fried and junk food, release of cortisol hormones because of excessive stress, excessive production of sebum and much more.
Researchers have found a relationship between stress and acne flare-ups, says the AAD. In response to stress, our bodies produce more androgens, a type of hormone. These hormones stimulate the skin's oil glands and hair follicles, which can lead to acne.

If you haven't gotten enough rest the night before, the telltale sign of sleeplessness could sit on top of your nose. Acne can flare up when you aren't getting enough sleep. In fact, sleep deprivation is considered one of the three main acne triggers, along with stress and sweating.
While stress alone isn't the cause of acne pimples — age, hormones, acne-producing bacteria and other factors are at play — it's evident that stress can trigger breakouts and make existing acne issues worse. “We know there are several things going on here,” says Dr.
