Studies show that chronic stress is often one of the root causes of adult acne and can exacerbate a minor skin issue. It also significantly increases sebum levels in the skin. The outbreak and increased oiliness occur when stress levels become so high that they increase hormone levels.
According to the Journal of American Academy of Dermatology, among women over the age of 25 in the United States, 54 percent have some form of facial acne.
The sebaceous follicle, a gland that secretes sebum to the hair and skin, is typically the culprit in the overproduction of oil associated with acne problems. The sebaceous follicle can begin over-producing sebum due to hormonal fluctuations, stress, changes in medicine, the use of new products, heat, and humidity.
