Black spots inside raised bumps on the skin can be caused by blackheads, sebaceous cysts or folliculitis, among other things.
1. Blackheads: Blackheads are a manifestation of acne and are caused by sebum accumulation in the hair follicles. Blackheads are caused by the opening of the hair follicle that is connected to the outside world, and the sebum is oxidized by the air, resulting in a blackened condition, which is often accompanied by an enlarged follicle opening. So there will be such phenomenon as black spots inside the raised bumps on the skin.
To treat blackheads, it is important to keep the skin clean, inhibit the overproduction of sebaceous glands, and control the infection of Propionibacterium acnes.

Sebaceous cysts: Sebaceous cysts are retention cysts formed when the sebaceous gland’s excretory ducts are blocked and the sebaceous gland’s cystic epithelium is swollen by the gradually increasing contents. The sebaceous cyst swelling has a pinhead-sized umbilical concave-like opening in the center of the swelling, which is bluish-black in color and shaped like a pinhead pimple. This is why there is such a phenomenon as a black spot inside a raised skin bump.
Sebaceous cysts, usually should eat a light diet, eat less spicy and greasy food, pay attention to facial hygiene, can not squeeze.
3. Folliculitis: Folliculitis is an inflammation of the entire hair follicle caused by bacterial infection. Folliculitis develops deeper and can cause perifolliculitis.
