Why do pimples develop?

The causes of acne are multifaceted, primarily including endocrine factors, excessive sebaceous gland secretion, blockage of the hair follicle sebaceous gland duct,不良 dietary and lifestyle habits, and infections. Specifically, during puberty, increased androgen secretion enhances sebaceous gland activity, leading to excessive oil production, which may trigger acne. Additionally, individuals with oily skin are prone to clogged pores due to excess sebum, making them more susceptible to acne. When sebum within the hair follicles cannot be effectively expelled, it leads to blockage of the follicular sebaceous duct, resulting in acne formation. Unhealthy dietary and lifestyle habits, such as a preference for spicy and irritating foods, long-term late-night activities, and excessive fatigue, can also contribute to acne development. Furthermore, inappropriate use of cosmetics, skincare products, or medications, as well as infections caused by bacteria, fungi, and other pathogenic microorganisms within the hair follicles, may also lead to acne. Therefore, maintaining skin cleanliness, adopting a balanced diet, following regular作息 routines, and appropriately using skincare products are important measures for preventing acne.
