SEBACEOUS HYPERPLASIA

CLINICAL OVERVIEW & TREATMENT APPROACH

Sebaceous hyperplasia is a benign condition caused by enlargement of the sebaceous (oil) glands. It most commonly appears as small, soft, yellowish or flesh-colored bumps on the face, particularly the forehead, cheeks, and nose.

Individual lesions represent enlargement of sebaceous glands with multiple glandular lobules surrounding a central dilated sebaceous duct. Lesions may be solitary but often occur in groups and may gradually increase in number over time.

Sebaceous hyperplasia is benign and has no malignant potential. Because the enlargement involves the glandular structure beneath the skin surface, treatment requires careful technique selection to balance lesion reduction, surrounding skin appearance, and risk of scarring or textural change.

At International Vein & Skin Institute, sebaceous hyperplasia is evaluated and treated by Dr. Jozef Tryzno, MD. Several surgical and laser techniques are available and may be used individually or in combination depending on the number and characteristics of the lesions, surrounding skin, vascular changes, and treatment goals.

CLINICAL EVALUATION

Evaluation begins with a focused clinical examination and, when appropriate, dermoscopic assessment. Key factors considered include:

Lesion size, depth, and number
Distribution and anatomic location
Stability versus progression
Skin type and healing characteristics
Diagnostic certainty

While many sebaceous hyperplasia lesions have a classic appearance, some require additional evaluation or biopsy to confirm the diagnosis before treatment is selected.

SEBACEOUS HYPERPLASIA VS. BASAL CELL CARCINOMA

Sebaceous hyperplasia and basal cell carcinoma (BCC) can occasionally appear similar on visual inspection, particularly when lesions are:

Flesh-colored or yellowish
Located on sun-exposed facial skin
Slowly enlarging

Sebaceous hyperplasia is benign and has no malignant potential. When a lesion has an atypical appearance or the diagnosis is uncertain, biopsy may be recommended before destructive treatment.

WHY SEBACEOUS HYPERPLASIA IS DIFFICULT TO TREAT

Sebaceous hyperplasia is challenging because the visible bump represents only part of the lesion. In many cases, the enlarged gland extends deeper beneath the skin surface.

Treatment may be limited by:

Deep glandular components
Risk of scarring with aggressive destruction
Residual glandular tissue and the possibility of recurrence
Development of new lesions over time due to ongoing sebaceous activity

For these reasons, treatment focuses on controlled removal and cosmetic improvement, often using individualized or staged approaches rather than attempting aggressive treatment in a single procedure.

TREATMENT OPTIONS AT IVSI

Sebaceous hyperplasia varies considerably from patient to patient. Some patients have one or two prominent lesions, while others have numerous small lesions accompanied by facial redness, visible blood vessels, sun damage, or uneven skin texture.

Several treatment methods are available at IVSI. Treatment may involve a single procedure or a combination of techniques performed in stages, depending on the clinical presentation and response to treatment.

CO₂ LASER ABLATION / DESTRUCTION

An ablative CO₂ laser may be used to precisely treat individual sebaceous hyperplasia lesions.

The laser allows controlled removal and evaporation of enlarged glandular tissue with limited procedural bleeding. Treatment depth is adjusted according to the size and characteristics of the lesion.

Because the glandular component may extend deeper than the visible surface bump, treatment must balance adequate lesion reduction against unnecessary tissue injury. Residual glandular tissue may remain, and additional treatment may occasionally be needed.

PULSED DYE LASER (PDL)

595-nm Pulsed Dye Laser (PDL) may be used when sebaceous hyperplasia is associated with superficial vascularity, telangiectasias, or facial redness.

PDL targets the vascular component rather than physically removing the enlarged gland. Depending on the presentation, it may be used alone for selected lesions or as part of combination treatment.

Er:YAG LASER & FRACTIONAL RESURFACING

2940-nm Er:YAG laser treatment may be used in selected patients for controlled treatment of superficial tissue and may also be incorporated into fractional resurfacing when skin texture, sun damage, or overall facial rejuvenation is part of the treatment plan.

Fractional resurfacing is not necessarily directed at removal of an individual enlarged gland. Its role may be to improve surrounding skin texture and blending as part of a broader treatment approach.

PUNCH EXCISION — SELECT LESIONS

For isolated, larger, or diagnostically uncertain lesions, punch excision may be appropriate.

This allows removal of the selected lesion and provides tissue for histopathologic examination when indicated. The treatment site is closed with sutures and results in a small linear scar that generally becomes less noticeable as it matures.

INDIVIDUALIZED & STAGED TREATMENT

There is no single treatment sequence for sebaceous hyperplasia.

A patient with one or two isolated lesions may require only treatment of those individual glands. Another patient may have numerous prominent lesions, while others may have sebaceous hyperplasia accompanied by facial redness, telangiectasias, sun damage, or uneven skin texture.

Depending on the presentation, treatment may involve CO₂ laser, PDL, Er:YAG, punch excision, or a combination of techniques.

When several components are present, treatment may be performed in stages so that the skin can heal and the response can be assessed before the next treatment is selected.

The combination and sequence are determined by the clinical presentation, lesion characteristics, surrounding skin, healing response, and treatment goals rather than by a predetermined treatment protocol.

EXPECTATIONS & RECURRENCE

Treatment can improve the appearance of existing sebaceous hyperplasia, but it does not eliminate the underlying tendency of sebaceous glands to enlarge.

Because sebaceous hyperplasia extends beneath the visible skin surface, an individual lesion may require more than one treatment to achieve satisfactory reduction. Treatment is intentionally controlled to balance improvement with the risk of scarring or textural change.

Individual treated lesions may persist or recur, and new lesions may develop over time as additional sebaceous glands enlarge.

Multiple treatments are therefore common with sebaceous hyperplasia, whether to further reduce an individual lesion, treat additional lesions, or address associated redness, vascular changes, sun damage, or surrounding skin texture.

YOUR ROLE IN PROPER HEALING

Following ablative treatment, temporary redness, mild swelling, crusting, or color difference between treated and untreated skin may occur during early healing.

Treated areas should be kept clean and protected from picking, scrubbing, unnecessary irritation, and excessive sun exposure while the skin heals. Specific aftercare instructions are provided according to the procedure performed.

When treatment is staged, adequate healing between procedures allows the treatment response and surrounding skin to be reassessed before additional treatment is performed.

IMPORTANT PROCEDURAL CONSIDERATIONS

Treatment planning considers the number and depth of lesions, facial location, skin type, surrounding sun damage and texture, vascular changes, diagnostic certainty, and individual healing characteristics.

More aggressive destruction is not necessarily better. Treatment depth must be balanced against the possibility of scarring, textural change, or pigmentary alteration, particularly on facial skin.

Sebaceous hyperplasia is benign, and treatment of established lesions is generally performed for cosmetic improvement. Biopsy or excision may be recommended when a lesion is atypical or the diagnosis is uncertain.

SCHEDULE A SKIN LESION EVALUATION

An evaluation can help determine whether facial bumps represent sebaceous hyperplasia or another type of skin lesion and which treatment approach is appropriate.
