What Are Sebaceous Cysts?

A sebaceous cyst is a non-cancerous growth that occurs in your sebaceous glands under your skin.

They form when a hair follicle ruptures, is injured or the duct is abnormal. Typically, these types of cysts don’t require treatment unless they become inflamed or infected. These cysts can occur on anyone’s body at any age.

Additional symptoms of cysts may include:

Sebaceous cysts occur when a hair follicle is swollen or ruptured, either due to acne, an injury to the skin or a sebaceous duct that’s malformed, while other times there may be no apparent cause.
