Sebaceous Cysts: Causes, Symptoms, and Safe Ways to Manage Them
A sebaceous cyst is a common type of skin lump that many people notice at some point in their lives. Although the name sounds concerning, most cases are harmless and slow-growing.
Sebaceous cyst is typically a small, closed sac under the skin filled with keratin (a protein found in skin, hair, and nails). These cysts can appear anywhere on the body but are most commonly found on the face, neck, back, or torso.
What causes sebaceous cysts?
Sebaceous (epidermoid) cysts usually form when skin cells become trapped under the skin instead of shedding normally. This can happen due to:
- Blocked hair follicles or skin pores
- Skin injury or trauma
- Hormonal changes in some cases
- Genetic factors in certain individuals
It is important to note that these cysts are not caused by poor hygiene and are not contagious.
