Acne occurs when increased sebum secretion prevents the sebum, which should be expelled from the pores, from coming out smoothly, leading to inflammation. At this time, it occurs as a result of the complex interaction of various factors, such as bacterial infections. Additionally, elevated levels of the stress hormone cortisol lead to increased sebum secretion, which is also one of the triggers for acne.
Adult acne is primarily caused by various factors such as stress, lack of sleep, and hormonal changes. In particular, women often experience breakouts around the chin and mouth depending on their menstrual cycle. You should not squeeze such acne yourself; it is essential to seek treatment from a professional. Also, please be careful, as using exfoliants too frequently can actually increase sebum production and worsen acne!
