Pimples, generally referred to as acne, may be related to factors such as heredity, elevated androgen levels, and keratinization of the sebaceous gland ducts of hair follicles. 1. Heredity: If there is a history of acne in the immediate family, there is a greater chance that the offspring will develop acne. 2. High androgen levels: If the body’s androgen secretion is high, it may lead to an increase in sebum secretion, and a large amount of sebum stagnation may induce acne. 3. Keratinization of follicular sebaceous gland ducts: If the follicular sebaceous gland ducts of the skin are keratinized, it may lead to clogging of the skin pores, and acne may be formed after the secretion gathers. If you have acne, you can consult a doctor for a clear diagnosis and follow the doctor’s instructions for medication.
