Many people confuse acne with folliculitis. In fact, the two diseases are not the same thing, but there is some overlap between the two diseases. Now let’s look at the definitions of the two diseases first! Acne: It is a chronic inflammatory disease that involves the sebaceous glands of hair follicles and is somewhat disfiguring. It is characterized by acne, papules, pustules, nodules, cysts, and scarring. It can occur in people of all ages, but is most prevalent in adolescents. Some people also refer to acne as pimples, which is incorrect because acne is only one manifestation of acne. Acne can also manifest as papules, pustules, nodules, cysts, and scarring. Folliculitis: This is an inflammation of the hair follicles caused by the invasion of purulent cocci, which is confined to the upper part of the hair follicles, and is divided into two types: purulent and non-purulent. Folliculitis begins as a red, congested papule that rapidly develops into a papulopustular sore, which then dries and crusts over, leaving no trace of scabbing. The rash is numerous, but not fused, and is itchy or mildly painful. This disease has been recorded in Chinese medicine for a long time. Those born in the hair area behind the neck are called “hair sores”; those born in the lower jaw are called “sheep’s beard sores”, “beard sores”, and “bird’s nest sores”. Those born in the lower jaw are called “sheep’s beard sores”, “beard sores”, and “bird’s nest sores”; those born between the eyebrows are called “eyebrow sores”; those born on the buttocks are called “sitting board sores”, etc. The difference between acne and folliculitis: 1. The causative factors are different The occurrence of acne is closely related to many factors such as excessive sebum secretion, blockage of hair follicle sebaceous ducts, bacterial infection and inflammatory reaction. The pathogenic bacteria that cause folliculitis are mainly Staphylococcus aureus, occasionally Staphylococcus epidermidis, Streptococcus, Pseudomonas and Escherichia coli. The hair pulling, friction, scratching caused by the injury, skin impregnation, local honey seal bandage and the application of corticosteroids are the causes of folliculitis. 2, inflammation involving different sites Acne is a chronic inflammation of the hair follicle sebaceous glands. Folliculitis is an inflammation limited to the upper part of the hair follicle. Acne can occur in people of all ages, but has the highest incidence in adolescents, mostly on the face. Folliculitis is more common in immunocompromised people or diabetic patients, and is more likely to occur on the head, neck, chest, back, and buttocks. 4.Different clinical manifestations Acne manifests as papules, pustules, nodules, acne, cysts, scarring, etc. Folliculitis starts as a red, congested papule, which rapidly develops into a papular pustule, followed by drying and crusting. Acne has a certain degree of cosmetic damage. Folliculitis crusts off without leaving a trace. It is not disfiguring. Do you understand this now?
