Risk factors
By Mayo Clinic staffNearly anyone can develop one or more epidermoid cysts, but these factors make you more susceptible:
- Being past puberty. Though they can occur at any age, epidermoid cysts rarely appear before puberty.
- Being male. Men are more likely to have epidermoid cysts.
- Having a history of acne. Epidermoid cysts are especially common in people who've had acne.
- Having significant sun exposure. Milia, seen mainly on the face, often occur in men and women with a long history of sun exposure.
- Experiencing skin injuries. Any traumatic or crushing injury to your skin — slamming your hand in a car door, for instance — increases your risk of an epidermoid cyst.
