Skin cysts, also known as sebaceous cysts, are slightly hardened, fluid-filled bumps within the skin. They can occur anywhere on the skin and often affect the face, neck, and torso. Instead, healthcare professionals call them epidermal cysts, keratin cysts, or epithelial cysts, according to American Family Physician. Skin cysts are benign, or noncancerous, and they usually do not cause problems. They do not tend to be painful or tender unless they become inflamed, damaged, or infected. Infections can occur if the cyst bursts.

Some glands are bigger than others, which means that they might secrete oil or keratin in a larger amount, making the cyst larger, too. In most cases, sebaceous cysts have a size ranging from 5 mm to 5 cm.
