What It Is
Defining Sebaceous Gland Hyperplasia
→ Sebaceous gland hyperplasia (SGH) is a common, benign skin condition caused by the overgrowth of sebaceous (oil) glands.
→ It usually appears as small, yellowish or flesh-colored bumps on the skin, often with a central indentation.
→ SGH occurs most frequently on the forehead, cheeks, and nose, but can also appear elsewhere on the face.
→ While not dangerous, SGH is often treated for cosmetic reasons, as the bumps may resemble acne, warts, or even skin cancer lesions.
Key Characteristics
- Small, soft papules (1–5 mm in size)
- Dome-shaped, sometimes with a central pit (umbilication)
- Most common in middle-aged and older adults
- More frequent in people with oily skin, rosacea, or history of sun damage
- Harmless, but may cause cosmetic distress
Why It’s Done
Main Reasons for Treatment
➡ Cosmetic Concerns – Patients often feel self-conscious about facial bumps.
➡ Misdiagnosis Prevention – SGH can resemble basal cell carcinoma; treatment ensures clarity.
➡ Texture Improvement – Smoother skin surface after treatment.
➡ Prevent Enlargement – Lesions can slowly grow larger if untreated.
➡ Emotional Confidence – Treating SGH improves self-image and quality of life.
Alternatives
Non-Medical Options
- Topical Retinoids (Tretinoin, Adapalene) → Help regulate oil glands and may shrink small lesions.
- Chemical Exfoliation → Mild peels (glycolic acid, salicylic acid) can improve appearance, though rarely eliminate bumps.
- Sun Protection → Prevents further sebaceous gland overgrowth and reduces worsening.
Medical Alternatives
→ If direct removal is not preferred, other therapies include:
- Laser Therapy (CO₂ or Erbium:YAG) → Vaporizes bumps with precision.
- Electrosurgery → Burns and removes growths using electric current.
- Cryotherapy → Freezes lesions with liquid nitrogen; less commonly used due to scarring risk.
- Photodynamic Therapy (PDT) → Combines light and photosensitizing agents to shrink sebaceous glands.
- Oral Isotretinoin → Rarely prescribed for extensive cases; reduces gland activity but has systemic side effects.
Preparation
Before Treatment
➡ Dermatology Consultation – A skin doctor examines lesions to confirm SGH and rule out skin cancer.
➡ Dermatoscopy or Biopsy – May be done if diagnosis is uncertain.
➡ Medication Review – Patients should inform doctors about current medications, especially blood thinners.
➡ Skin Cleansing – Area should be clean and makeup-free before treatment.
➡ Expectation Setting – Patients are advised that SGH may recur, and multiple treatments could be needed.
How It’s Done
Common Treatment Methods in Korea
1. Laser Therapy
→ The most popular treatment in Korean dermatology.
- CO₂ Laser or Erbium:YAG Laser precisely vaporizes lesions.
- Provides smooth results with minimal scarring.
- Quick recovery time compared to older surgical methods.
2. Electrosurgery (Electrocautery)
→ A fine electric probe burns and removes SGH lesions.
- Effective for small bumps.
- May leave mild redness that fades over weeks.
3. Cryotherapy
→ Freezing lesions with liquid nitrogen.
- Not commonly favored in Korea due to higher risk of scarring or pigment change.
4. Photodynamic Therapy (PDT)
→ Involves applying a light-sensitive chemical to the skin, then activating it with laser/light.
- Shrinks oil glands and reduces new SGH formation.
- Often combined with lasers for improved outcomes.
5. Oral or Topical Retinoids
→ Used as preventive maintenance for patients with frequent recurrences.
- Helps regulate sebaceous gland activity.
Treatment Course
- Most treatments are outpatient procedures taking less than 30 minutes.
- Often completed in one session, though multiple visits may be required for widespread SGH.
- Maintenance with skincare and sun protection is crucial to prevent new lesions.
Recovery
Immediate Recovery
- Laser and Electrosurgery → Redness, mild swelling, and small scabs for 3–7 days.
- Cryotherapy → Blistering and crusting possible, healing within 1–2 weeks.
- Photodynamic Therapy → Redness and peeling similar to a mild sunburn for several days.
Long-Term Recovery
→ Skin heals within 1–3 weeks depending on treatment method.
→ Lesions typically do not scar if treated properly.
→ Recurrence is possible, requiring repeat treatments every few years.
→ Ongoing skincare with SPF, moisturizers, and gentle exfoliants helps maintain results.
Complications
Possible Risks
- Pigment Changes → Hypopigmentation or hyperpigmentation, more common in darker skin types.
- Scarring → Rare, especially with precise laser therapy.
- Infection → Uncommon, but possible if scabs are picked or aftercare is neglected.
- Recurrence → SGH often reappears over time, even after successful removal.
- Prolonged Redness → May persist for weeks with aggressive treatments.
