Pigment and laser consultation guide
PICOHI is a picosecond Nd:YAG laser platform. The manufacturer describes a 300-picosecond pulse duration and 1064 nm and 532 nm handpiece options. Product specifications and approved uses can vary by region; diagnosis, wavelength, handpiece and settings must be selected by a physician.
General information only. A physician must confirm diagnosis, suitability, risks and the final treatment plan.
Diagnosis comes before the laser name
Brown spots and uneven tone can have different causes, and not every pigmented lesion should be treated with the same laser. A physician should first identify the likely condition, review your skin type and sun exposure, and explain whether laser treatment could worsen pigmentation.
Before treatment and pricing
- Disclose recent tanning or sunburn, photosensitizing medicines, pregnancy, active rash or infection, cold sores, pigment disorders and previous laser reactions.
- Price depends on the diagnosed condition, area, handpiece, number of passes and session plan—not simply the device name.
- International patients should plan strict sun protection and confirm what follow-up is needed if pigment changes after leaving Korea.
Possible effects and safety
- Temporary redness, swelling, warmth, pinpoint bleeding or crusting may occur depending on settings and indication.
- Post-inflammatory darkening or lightening, blistering, infection, scarring or an unsatisfactory response are possible. Risk differs by skin and diagnosis.
- Do not treat an undiagnosed lesion based only on an online photo. Seek medical review for a changing, bleeding or otherwise concerning spot.

How many laser sessions are needed?
The diagnosis, color, depth, response and treatment goal determine the plan; there is no universal count.
What affects the price?
Condition, area, handpiece, passes and planned sessions are common price factors.
