Sebaceous Hyperplasia: Causes, Symptoms, and Diagnosis
Sebaceous hyperplasia is a common skin condition that many people encounter, especially as they age. While it is generally harmless, it can be aesthetically displeasing and sometimes confused with more severe skin issues.
What is Sebaceous Hyperplasia?
Sebaceous hyperplasia occurs when the sebaceous glands, which are responsible for producing oil (sebum) to keep your skin lubricated, become enlarged. This enlargement results in small, yellowish bumps on the skin, most commonly appearing on the face, particularly on the forehead, cheeks, and nose.

Age and Hormonal Changes
One of the primary causes of sebaceous hyperplasia is aging. As we get older, our skin undergoes various changes, including the enlargement of sebaceous glands. Hormonal fluctuations, especially an increase in androgens, can also contribute to the development of this condition.
Genetic Factors
Genetics play a significant role in determining who might develop sebaceous hyperplasia. If your family has a history of this condition, you are more likely to experience it yourself.
Excessive Sun Exposure
Prolonged sun exposure can damage the skin and contribute to the enlargement of sebaceous glands. It’s crucial to protect your skin from the sun to minimize the risk of developing sebaceous hyperplasia.
Symptoms of Sebaceous Hyperplasia
Sebaceous hyperplasia is characterized by small, yellowish or flesh-colored bumps that are generally painless. These bumps are usually soft and may have a central depression or dimple. While they are most commonly found on the face, they can also appear on other parts of the body.
Common Locations
- Face: Forehead, cheeks, and nose are the most common areas.
- Chest and Back: Though less common, sebaceous hyperplasia can also occur here.
- Genital Area: Rare, but possible.
Diagnosis of Sebaceous Hyperplasia
Diagnosing sebaceous hyperplasia is usually straightforward for dermatologists. A visual examination is often sufficient, but in some cases, a biopsy may be performed to rule out other skin conditions like basal cell carcinoma.
Differential Diagnosis
- Basal Cell Carcinoma: A type of skin cancer that can appear similar to sebaceous hyperplasia.
- Milia: Small, white cysts that can be confused with sebaceous hyperplasia.
- Acne: While acne and sebaceous hyperplasia can appear similar, they have different underlying causes and treatments.
Treatment of Sebaceous Hyperplasia
Topical Treatments
- Retinoids: These vitamin A derivatives can help reduce the size of sebaceous glands and prevent new bumps from forming.
- Chemical Peels: Peels containing salicylic acid or glycolic acid can exfoliate the skin and reduce the appearance of sebaceous hyperplasia.
Medical Procedures
- Laser Therapy: Lasers like the pulsed dye laser or CO2 laser can effectively reduce or eliminate sebaceous hyperplasia bumps.
- Electrosurgery: This involves using an electric current to remove the bumps.
- Cryotherapy: Freezing the bumps with liquid nitrogen can also be an effective treatment.
At-Home Remedies
- Warm Compresses: Applying a warm compress can help reduce swelling and make the bumps less noticeable.
- Gentle Exfoliation: Regular, gentle exfoliation can help keep your skin clear and may reduce the appearance of sebaceous hyperplasia.

Sun Protection
Wearing sunscreen daily can help protect your skin from the harmful effects of UV rays, which can exacerbate sebaceous hyperplasia.
Skincare Routine
Maintaining a proper skincare routine that includes cleansing, moisturizing, and exfoliating can help manage sebaceous hyperplasia. Use non-comedogenic products to avoid clogging your pores.
Regular Dermatologist Visits
Regular check-ups with a dermatologist can help you manage sebaceous hyperplasia effectively and catch any potential skin issues early.
When to See a Doctor
While sebaceous hyperplasia is generally harmless, you should consult a dermatologist if you notice any changes in the appearance of the bumps, such as rapid growth, bleeding, or changes in color. These could be signs of a more serious condition that requires medical attention.
