What does acne look like

summary

We all know that acne is actually a kind of skin disease. It's easy for most people to appear on their faces during adolescence, especially for boys. If they don't receive treatment, most people will automatically disappear after adolescence. Here's how acne looks.

What does acne look like

First: the typical skin lesions of closed acne (also known as white head) are skin papules about 1 mm in size, without obvious hair follicle openings. Nodules larger than 5 mm in diameter with induration and pain; cysts deeper, filled with a mixture of pus and blood. These lesions can also fuse to form large inflammatory plaques and sinuses.

Second: open acne (also known as blackhead) is characterized by a domed papule with a significantly dilated follicle opening. Further development of acne will evolve into a variety of inflammatory lesions, manifested as inflammatory papules, pustules, nodules and cysts. Inflammatory papules were red, ranging in diameter from 1 mm to 5 mm; pustules of the same size were filled with white pus.

Third: pigmentation, persistent erythema, sunken or hypertrophic scars are often left after the inflammatory lesions subside. Clinically, according to the nature and severity of acne lesions, acne can be divided into three grades: Grade 1 (mild): only acne; grade 2 (moderate): in addition to acne, there are some inflammatory papules; grade 3 (moderate): in addition to acne, there are more inflammatory papules or pustules; grade 4 (severe): in addition to acne, inflammatory papules and pustules, there are nodules, cysts or scars.
