Treatment Overview
The Q-Switched Alexandrite Laser operates at a 755 nm wavelength, which is strongly absorbed by melanin. It delivers nanosecond pulses to shatter pigment clusters, making it a well-established tool for pigmented lesions, freckles, café-au-lait spots, and dermal pigmentation.
In Korea, the Q-Switched Alexandrite Laser is used for stubborn melasma cases or melasma mixed with other congenital pigmentation. However, due to its higher melanin absorption, it must be used conservatively on Asian skin to minimize the risk of post-inflammatory hyperpigmentation (PIH). Korean dermatologists often combine Alexandrite with Nd:YAG toning, Pico Lasers, or Gold Toning to create a safer multi-layer melasma protocol.
It belongs to the Pigmentation Treatment family (Q-Switched Alexandrite, Nd:YAG Toning, Dual Toning, Gold Toning, Pico Lasers, Fraxel, Clear + Brilliant, CO₂):
- Q-Switched Alexandrite (755 nm): Best for resistant melasma + mixed pigment lesions.
- Nd:YAG Toning (1064 nm): Best for dermal melasma.
- Dual Toning (532 + 1064 nm): Best for multi-layer melasma.
- Gold Toning (595 nm): Best for vascular melasma.
- Pico Lasers: Best for stubborn melasma + PIH with lower PIH risk.
- Fraxel Dual: Best for melasma + sun damage + texture.
- Clear + Brilliant: Best for mild melasma + prevention.
- CO₂ Fractional: Best for melasma + scars/texture (with caution).
Purpose & Benefits
- Stubborn Melasma Clearance: Helps lighten pigment unresponsive to toning lasers.
- Deep Pigment Targeting: Reaches dermal pigment and congenital pigmentation.
- Freckle & Spot Removal: Works on additional pigmentation beyond melasma.
- Combination Synergy: Often paired with Pico or Nd:YAG lasers for safer results.
- Skin Brightening: Improves clarity and glow.
Ideal Candidates
Q-Switched Alexandrite Laser in Korea is recommended for:
- Adults with recurrent or resistant melasma.
- Patients with melasma plus congenital pigment lesions (like café-au-lait spots).
- Individuals needing deeper pigment targeting beyond superficial toning.
Treatment Comparison:
- Alexandrite: Best for resistant melasma + congenital pigment.
- Nd:YAG: Best for dermal melasma.
- Dual Toning: Best for multi-layer melasma.
- Gold Toning: Best for vascular melasma.
- Pico Lasers: Best for stubborn melasma + PIH with collagen benefits.
- Fraxel Dual: Best for melasma with texture/sun damage.
- Clear + Brilliant: Best for mild/maintenance melasma.
Possible Risks & Complications
Because it strongly targets melanin, risks are higher than gentler lasers if misused:
- Redness & Warmth: Temporary, fades within 24–48 hours.
- Temporary Darkening: Pigment may darken before fading.
- PIH (Post-Inflammatory Hyperpigmentation): Risk if aggressive settings are used.
- Rare Risks: Hypopigmentation or mottling.
Surgical Techniques Used
- 755 nm Wavelength: Targets melanin with high absorption.
- Nanosecond Pulses: Break pigment into fine fragments for clearance.
- Combination Protocols: Often layered with Nd:YAG, Pico, or Gold Toning for melasma.
- Protocol: 3–6 sessions spaced 4–6 weeks apart; cautious settings for melasma patients.
Recovery & Aftercare
- Immediately: Redness, warmth, or slight swelling.
- 2–5 Days: Pigment may darken and form micro-crusts.
- 1–2 Weeks: Progressive fading and clearer tone.
Aftercare Tips:
- Daily SPF 50+ sunscreen is mandatory.
- Use hydrating creams and barrier-supporting serums.
- Avoid sun, scrubs, or harsh acids for 5–7 days.
- Do not pick at crusts or scabs.
Results & Longevity
- After First Session: Subtle brightening and pigment darkening.
- Short-Term (2–3 Sessions): Visible melasma fading.
- Medium-Term (3–6 Sessions): Noticeable clearing of resistant pigmentation.
- Long-Term: Results may last 6–12 months, but maintenance is often required for melasma.
Treatment Process in Korea
- Consultation & Skin Analysis – Identify melasma type and pigment depth.
- Preparation – Cleansing, protective eyewear, optional numbing cream.
- Alexandrite Session – Focused nanosecond pulses delivered to pigmentation.
- Post-Care: Cooling mask, hydration, or whitening serums.
- Follow-Up: Multi-session plan with adjunctive toning or Pico lasers.
Why Korea is a Top Destination
- Korea’s dermatologists excel at safe Alexandrite use for Asian skin, minimizing PIH risk.
- Clinics combine Alexandrite with Pico, Nd:YAG, or Gold Toning for safer melasma control.
- More affordable than Western pigmentation treatments.
- Seoul clinics frequently add skin boosters (Rejuran, PN, exosomes) for better recovery.
- Known globally for advanced melasma and pigmentation programs.
Cost Range (Estimated)
- Single Session (full face): USD 200 – 400
- 3–6 Session Package: USD 800 – 2,000
- Premium Package (Alexandrite + Pico/Nd:YAG + Boosters): USD 1,500 – 3,500
Additional Costs:
- Consultation: USD 20 – 50
- Add-ons (Exosomes, PN boosters, whitening drips): USD 100 – 400
💡 The Q-Switched Alexandrite Laser is often called “the resistant pigment eraser” in Korea, but because of its strong melanin absorption, it is used carefully and often in combination therapies for melasma.
