Short answer:
Pico toning uses very short, low-energy picosecond laser pulses to break up pigment with less heat than older lasers. For melasma, most plans involve 5–10 sessions spaced 1–2 weeks apart, because gentle, repeated treatment is safer than aggressive single sessions, followed by maintenance. Each session in Gangnam typically costs ₩50,000–₩150,000 (about $40–$110).
How pico toning works
Picosecond lasers fire pulses lasting trillionths of a second. The rapid photoacoustic effect shatters pigment into tiny particles that the immune system then clears, while producing less heat than nanosecond Q-switched lasers. In toning mode, the energy is spread evenly across the face at low fluence, aiming to lighten pigment without inflaming the skin. See our pico toning guide.
Why melasma needs multiple sessions
Melasma pigment sits at different depths and is continuously produced under the influence of hormones, sun and visible light, inflammation and abnormal blood vessels. Each low-energy session removes a little pigment without provoking the skin. Pushing energy too high to speed things up can trigger rebound darkening or mottled white spots, so careful clinics stay conservative.
A typical session plan
Sessions 1 to 3
The overall tone looks slightly brighter and clearer, but melasma patches may not change much yet.
Sessions 4 to 7
Patches start to fade and their edges soften.
Sessions 8 to 10
A clearer improvement is usually visible. The doctor reviews progress and decides whether to continue, pause or change approach.
Maintenance
Sessions every 1–2 months, especially before and after summer, with daily sun protection.
What a session is like
- Cleansing and eye protection.
- Sometimes numbing cream, though many people do not need it.
- 10–15 minutes of laser passes with a light snapping sensation.
- A soothing mask and sunscreen; makeup is usually fine the same day.
Combining pico toning with other treatments
Pico toning works best as part of a melasma program. Common partners include Sylfirm X
for the vascular and basement membrane component, prescription topicals such as tranexamic acid or azelaic acid, and, after screening, oral tranexamic acid. Hydrating boosters can support the skin barrier.
Risks and how clinics reduce them
- Rebound pigmentation:
minimised with low fluence and adequate intervals.
- Mottled hypopigmentation:
white spots from over-treatment; another reason not to rush.
- Temporary redness or dryness:
usually settles within hours.
