Sebaceous hyperplasia: pictures, diagnosis and treatment options
Updated: Oct 11
Sebaceous hyperplasia is a benign enlargement of the skin’s oil glands. It usually appears as small skin-coloured or yellowish bumps on the face. Once the diagnosis is confirmed, treatment is optional. People most often consider removal because the bumps are noticeable or repeatedly irritated.
What does sebaceous hyperplasia look like?
Typical lesions occur on the forehead, cheeks, nose and temples. They are rounded, slightly raised and often have a small central depression. Although a bump may resemble a spot, it is not ordinary inflammatory acne and squeezing does not reliably remove the enlarged gland.
This photograph from the clinic’s archive shows an individual treatment example on the forehead. Lighting, facial position and the time since treatment matter when comparing photographs. A result in one person does not predict another person’s outcome, and an image cannot replace diagnosis.
Why do the oil glands enlarge?
Sebaceous glands produce sebum. In hyperplasia, the lobules of a gland become enlarged. These changes are more common with age and depend partly on individual skin characteristics. Numerous lesions can sometimes be associated with medication, including immunosuppressive treatment.
Sebaceous hyperplasia is not caused by poor hygiene and is not an infection. It is not contagious. Tell your doctor if many bumps appear quickly or after a medication change; do not stop prescribed medicines yourself.
What can look similar?
Milia are usually firm white superficial cysts. Comedones develop in blocked follicles. Fordyce spots on the lips are visible sebaceous glands in a different location. Syringomas arise from sweat ducts and often occur around the eyes.
An important distinction is basal cell carcinoma. A single shiny bump with a depression or visible vessels can resemble sebaceous hyperplasia. This resemblance does not mean that benign hyperplasia turns into cancer.
How is the diagnosis confirmed?
The doctor considers the location, number and duration of the bumps, changes over time, the surrounding skin and medicines. Dermoscopy helps examine the structure and blood vessels. A typical pattern can often be diagnosed clinically.
A lesion that differs from the others, grows, bleeds or develops a persistent crust may need a biopsy and microscopic examination. Destroying a suspicious lesion for cosmetic reasons before clarifying its diagnosis can remove tissue needed for testing.
When is observation enough?
Confirmed benign lesions do not have to be removed if they do not bother you. Observation is a reasonable option. Photographs can help document changes.
Treatment may be worthwhile for cosmetic concerns, repeated trauma or irritation. The decision also depends on lesion numbers, skin tone, scarring risk and the amount of recovery time that fits your circumstances.
Treatment options and limitations
Local laser treatment, including ablative approaches, can target individual lesions. Electrocautery uses electrical energy. Cryotherapy, selected surgical techniques and photodynamic therapy may be considered in suitable cases. Potential limitations include scarring, changes in pigmentation, incomplete removal and recurrence.
For extensive or particularly troublesome disease, a dermatologist may consider medication such as oral isotretinoin. It requires assessment of contraindications and monitoring. Lesions can return after treatment stops, so it is not a universal substitute for a procedure or a medicine to take without supervision.
The diagnosis alone does not determine the method. Deeper treatment does not automatically give a better cosmetic result: reducing the bump must be balanced against the risk of a mark on the skin.
Clinical examples and planning treatment
The gallery contains comparative photographs of small skin lesions from the clinic’s archive. It supports the discussion of treatment but does not establish a diagnosis for a similar-looking bump.
Laser methods are central to treating these changes at Dr USKOV Kliinik. Dr Alexander Uskov selects an individual author-developed protocol based on the depth and number of lesions, skin condition and the patient’s priorities. A range of lasers and other medical technologies supports choosing an appropriate approach; combining methods is considered when indicated.
Recovery and aftercare
Redness, swelling, small crusts or superficial wounds can occur after treatment. Healing depends on the method, treatment area and skin. A fixed recovery period or number of sessions cannot be promised to everyone.
Do not pick crusts or apply acids and irritating products to unhealed skin. The doctor will explain cleaning, wound care and when makeup can resume. Once the surface has healed, sun protection is important. Increasing pain, spreading redness or pus should prompt contact with the clinic.
Can the bumps be removed at home?
Squeezing, piercing and chemical burning can cause inflammation, pigmentation or scars. Products intended for oily skin cannot guarantee that established enlarged glands will disappear.
Common questions
Can sebaceous hyperplasia return?
A treated lesion may recur, and new lesions can develop with time. A procedure does not remove all the underlying skin characteristics. Further treatment is assessed after healing and review of the result.
Does everyone need laboratory tests?
Usually, examination and dermoscopy when indicated are more useful than a routine panel of blood tests. Additional investigations depend on the clinical findings.
Should every bump be treated in one visit?
Not necessarily. Numerous lesions or a higher risk of pigmentation changes may favour staged treatment. The plan, recovery and realistic cosmetic improvement are discussed before the procedure.
