Laser toning (레이저 토닝).

A low-fluence Q-switched Nd:YAG laser (or a picosecond variant) is applied in gentle passes across the face. Unlike traditional pigment-targeting lasers, toning uses sub-threshold energy — enough to fragment pigment, not enough to cause visible inflammation or PIH rebound. Patients typically receive 5–10 sessions spaced 1–2 weeks apart.

Melasma, post-inflammatory hyperpigmentation, uneven tone, dull complexion. Particularly effective for the darker skin types (III–V) that Korean dermatologists see at high volume — the protocol was developed partly to avoid the PIH risk of higher-energy lasers in those skin types.

Spectra (Lutronic, Korean manufacturer) is the classic toning platform. Newer pico devices — PicoSure, PicoWay, PicoPlus, Discovery Pico — are used in combination. Most Gangnam dermatology clinics stock two or more of these.

Often combined with oral or topical tranexamic acid for melasma cases. Post-session sun protection is non-negotiable. A full course is typically 5–10 sessions, sometimes extending to 15–20 for stubborn melasma. Maintenance sessions every 4–8 weeks are common long-term.

Near-zero. Mild pink flush for 1–2 hours, occasional tiny scabs at pigment sites that resolve in 3–5 days. Makeup can be applied after the pinkness resolves.

Per session: ₩100,000–₩300,000 for Spectra. Pico sessions: ₩200,000–₩400,000. Course of 5: ₩500,000–₩1,500,000, often with a 10–20% package discount.

"What's your energy setting for my skin type, and what's your policy if I develop PIH from a session?" A careful dermatologist tracks the setting per patient and has a clear de-escalation protocol.
