Treatment Overview
The Q-Switched Nd:YAG Laser is considered one of the gold-standard devices for birthmark and pigmentation correction. Operating at 1064 nm (deep penetration) and 532 nm (superficial pigment), it delivers ultra-short, high-intensity pulses that selectively fragment melanin and pigment particles into tiny fragments, which the body gradually clears.
In Korea, the Q-Switched Nd:YAG Laser is a primary treatment option for pigmented birthmarks such as Ota nevus, café-au-lait spots, congenital nevi, and dermal pigmented lesions. It is also used for freckles, age spots, melasma, and tattoos, making it highly versatile. Korean dermatologists often use it in low-fluence laser toning protocols for safe pigment reduction in Asian skin prone to PIH (post-inflammatory hyperpigmentation).
It belongs to the Birthmark & Pigmentation Treatment family (Q-Switched Nd:YAG, Alexandrite, Ruby, Pico Lasers, CO₂ Fractional, IPL):
- Q-Switched Nd:YAG (1064/532 nm): Best for dermal pigment + Ota nevus + congenital marks.
- Alexandrite (755 nm): Best for congenital pigmented lesions (café-au-lait).
- Ruby (694 nm): Best for resistant pigmented lesions.
- Pico Lasers (PicoCare, PicoPlus, PicoSure): Best for stubborn pigment + scars.
- CO₂ Fractional: Best for superficial pigmented lesions + textural irregularities.
- IPL: Best for redness + superficial vascular-pigment issues.

Surgical Techniques Used
Q-Switched Nd:YAG Laser uses selective photothermolysis with nanosecond pulses:
- 1064 nm Wavelength: Penetrates deep dermis for Ota nevus, congenital nevi, and tattoos.
- 532 nm Wavelength: Targets superficial freckles, sunspots, and café-au-lait.
- Low-Fluence Toning Mode: Safe gradual pigment reduction.
- Protocol:
- Birthmarks: 3–10 sessions spaced 3–4 weeks apart.
- Pigmented lesions: 2–5 sessions depending on depth.
- Maintenance: Every 6–12 months for melasma or recurring pigment.
Recovery & Aftercare
- Immediately: Mild redness, tingling, or warmth.
- 2–5 Days: Temporary crusting or darkening.
- 1–2 Weeks: Visible pigment fading.
Aftercare Tips:
- Apply SPF 50+ daily.
- Use hydrating and barrier-strengthening creams.
- Avoid picking at crusts or scabs.
- Avoid strong acids, scrubs, and retinoids for 5–7 days.
Results & Longevity
- After First Session: Initial lightening and brighter tone.
- Short-Term (2–4 Sessions): Noticeable fading of birthmarks or spots.
- Medium-Term (5–8 Sessions): Significant improvement in congenital pigment.
- Long-Term: Many results are permanent; maintenance may be needed for melasma or recurring lesions.
