Acne is the scientific name for pimples, and both refer to chronic inflammatory diseases of the sebaceous glands of hair follicles, with no substantive difference. Acne is a common chronic inflammatory disease that occurs in the sebaceous glands of hair follicles, characterized by pimples, papules, pustules, and scarring, and is often referred to as acne because it occurs during puberty. The onset of acne is related to increased sebum secretion, Propionibacterium acnes colonization, and follicular sebaceous gland duct keratinization. Acne patients should pay attention to their daily diet and living habits, eat less high-sugar or greasy food, avoid staying up late, and pay attention to skin sun protection and cleaning. Treatment includes topical retinoic acid cream, oral isotretinoin soft capsule and so on. Specific medication for acne should be taken under the guidance of a specialist, and should not be used without authorization.
