Blackheads are clinically referred to as open pimples. Physiological factors such as staying up all night may induce open pimples, but the cause of their formation may also be related to androgens and abnormal keratinization of the follicular sebaceous gland ducts.
1. Physiological factors: Staying up all night may trigger the formation of blackheads and acne, and physiological factors such as overwork and mental stress may also lead to sebum secretion, which in turn triggers open pimples.
2. Androgens: abnormal androgens may cause increased sebum secretion, leading to the formation of open pimples.
3. Abnormal keratinization of follicular sebaceous gland ducts: If the follicular sebaceous glands have hyperkeratotic ducts, their orifices will become smaller and clogged, which may trigger the appearance of open pimples.
There are many causes of open pimples, so it is recommended that the patient go to a regular hospital and undergo a relevant examination to determine the cause.
