Sebaceous cysts: main causes and home remedies.

Many people use the term “sebaceous cyst” to refer to a small, round lump under the skin, but in many cases, it is actually an epidermoid or epidermal inclusion cyst. These cysts are usually harmless, grow slowly, and often require no treatment unless they become painful, inflamed, infected, or bothersome.

What causes a sebaceous cyst?

These cysts can form when surface skin cells migrate into deeper layers instead of shedding normally, or when there is irritation, injury, or blockage in a hair follicle. The Cleveland Clinic also notes that epidermal inclusion cysts can form after a blockage at the top of a hair follicle.

What does it usually look like?

A typical skin cyst is usually a round lump under the skin. It may be painless and slow-growing, and many people only notice it when they touch it or when it becomes more visible. The NHS (National Health Service of the UK) states that skin cysts are usually harmless, while the Mayo Clinic notes that epidermoid cysts are typically slow-growing and painless.
