Treatment Overview
Photodynamic Therapy (PDT) with Blue Light is an advanced acne treatment widely used in Korean dermatology clinics for moderate to severe or cystic acne. The procedure combines a photosensitizing agent (most commonly 5-aminolevulinic acid, ALA, or methyl aminolevulinate, MAL) with Blue Light LED (415 nm) activation.
Once the agent is absorbed into the sebaceous glands, the Blue Light activates it, generating a photochemical reaction that destroys acne-causing bacteria (Cutibacterium acnes) and selectively damages overactive sebaceous glands. This dual mechanism provides long-term acne reduction compared to standard Blue Light LED therapy alone.
Purpose & Benefits
- Sebaceous Gland Suppression: Decreases oil production, reducing recurrence.
- Bacterial Elimination: Blue light activation destroys C. acnes.
- Inflammation Control: Reduces swelling and redness in cystic acne.
- Scar Prevention: Treats acne at the source, lowering the risk of deep scars.
- Dual Action: Stronger and longer-lasting than standalone Blue Light.
Ideal Candidates
PDT with Blue Light Therapy in Korea is recommended for:
- Patients with moderate to severe inflammatory or cystic acne.
- Individuals with acne unresponsive to topical or oral medications.
- Patients looking for a non-oral alternative to isotretinoin (Accutane).
- Those with frequent, scarring acne flare-ups.
Possible Risks & Complications
PDT is generally safe under Korean dermatology standards, but stronger than standard LED therapy. Side effects may include:
- Redness & Swelling: Common, lasts 1–3 days.
- Peeling or Crusting: 3–7 days as treated skin renews.
- Photosensitivity: High sensitivity to sunlight/strong light for 24–48 hours after treatment.
- Rare Risks: PIH (post-inflammatory hyperpigmentation) if overly aggressive protocols are used—minimized with Korea’s low-fluence, fractionated approaches.
Surgical Techniques Used
- Topical Photosensitizer (ALA/MAL): Applied to acne-prone areas and incubated for 30–90 minutes.
- Blue Light LED (415 nm): Activates the agent, initiating selective destruction of sebaceous glands and acne bacteria.
- Protocol: 2–4 sessions, spaced 3–4 weeks apart, depending on acne severity.
Recovery & Aftercare
Immediately: Redness, mild swelling, and warmth.
1–3 Days: Skin remains sensitive; strict light avoidance required.
5–7 Days: Peeling or crusting resolves, revealing smoother skin.
1–2 Weeks: Breakouts significantly reduced.
Aftercare Tips:
- Avoid sunlight and strong indoor lighting for at least 48 hours post-treatment.
- Apply SPF 50+ sunscreen diligently once skin recovers.
- Use hydrating creams and barrier ointments to support healing.
- Avoid exfoliants, acids, or retinoids for 1–2 weeks.
Results & Longevity
- After 1 Session: Noticeable reduction in active breakouts.
- After 2 Sessions: Fewer cystic lesions, calmer skin.
- After 3–4 Sessions: Long-term suppression of acne and reduced oil production.
Results may last 6–12 months or longer, with some patients experiencing permanent improvement in oil control.
