Sebaceous Cysts: Causes and Treatment
What is a Sebaceous Cyst?
A sebaceous cyst is a small, non-cancerous lump under the skin that forms when sebaceous glands (which produce oil) get blocked. They often appear on the face, neck, or back and are filled with keratin, a thick, cheese-like substance.
Causes:
- Blocked Glands or Follicles: Often due to excess oil, dead skin, or injury to the skin.
- Genetics: Some people are genetically prone to cysts.
- Acne: Severe acne can lead to cyst formation.
- Hormonal Changes: Fluctuations in hormones can contribute to blockage.
Symptoms:
- Round, smooth bump beneath the skin
- Painless, unless infected
- May become tender, red, or swollen if inflamed or infected
Treatment:
- Leave it Alone: Small cysts often don’t need treatment.
- Warm Compress: Can help the cyst drain naturally.
- Antibiotics: If infected, though they won’t remove the cyst.
- Surgical Removal: The most effective option for larger or recurring cysts.
- Drainage: Can temporarily relieve discomfort, but the cyst may come back.
Prevention:
- Keep skin clean to prevent blockages.
- Manage acne to reduce the chance of cysts forming.
- Avoid skin trauma (e.g., popping pimples).
