Symptoms of acne

Acne is actually a chronic inflammatory skin disease caused by the sebaceous glands on the hair follicles of people's skin. When this disease occurs, most patients appear in adolescence, that is, between the ages of sixteen and eighteen. But there are also some cases where the disease occurs earlier. However, what exactly are the symptoms of acne? Let’s take a look at the relevant knowledge and suggestions.

The symptoms of acne are actually quite obvious. After this disease occurs, skin lesions tend to occur on people's faces, upper chest and back. The appearance of acne is not a manifestation of inflammatory skin lesions. They occur as open and closed comedones. Closed comedones are skin-colored papules about one millimeter in size on your skin, with no obvious hair follicle openings.

Open comedones (also known as blackheads) appear as dome-shaped papules with significantly dilated follicular openings. Acne will further develop into various inflammatory skin lesions, manifesting as inflammatory papules, pustules, nodules and cysts. Inflammatory papules are red, with a diameter ranging from 1 to 5 mm; pustules are uniform in size and filled with white pus; nodules are larger than 5 mm in diameter, feel hard and painful to the touch; cysts are located deeper and are filled with a mixture of pus and blood.

These lesions may also fuse to form large inflammatory plaques and sinus tracts. After the inflammatory skin lesions subside, pigmentation, persistent erythema, and depressed or hypertrophic scars are often left behind. Clinically, acne is divided into 3 or 4 grades according to the nature and severity of acne lesions: Grade 1 (mild): only comedones; Grade 2 (moderate): in addition to comedones, there are also some inflammatory papules; Grade 3 (moderate): in addition to comedones, there are also more inflammatory papules or pustules; Grade 4 (severe): in addition to comedones, inflammatory papules and pustules, there are also nodules, cysts or scars.
