Pico Laser

How it works

A picosecond laser delivers energy in trillionths of a second, which acts more as a mechanical shock than a heating effect. That may fragment pigment particles and, with certain fractionated handpieces, stimulate skin remodeling for texture and some acne scars. Outcomes depend on the pigment type, the wavelength and the settings, and they vary by person.

Who it may suit

• Sunspots, freckles and some pigmented marks
• Uneven tone when gentler toning has plateaued
• Mild to moderate acne scarring with a fractional handpiece
• People who can accept a few days of spot crusting for targeted work

The treatment day

1. Assessment. The doctor examines the pigment or scar pattern, asks about melasma history, medications and recent sun, and explains which handpiece fits.
2. Test and plan. For some people a small test area is treated first. The wavelength, spot size and interval between sessions are explained.
3. Treatment. Eyewear is worn and pulses are delivered with a snapping or prickling feeling. Numbing cream is used for more sensitive or spot work.
4. Aftercare. Cooling and a protective ointment may be applied, and written instructions explain how to care for scabs if they form.

Aftercare

• Do not pick at small scabs and let them fall off on their own
• Apply ointment or dressings exactly as advised
• Use sunscreen daily and avoid tanning
• Keep skincare gentle until redness settles
• Report blistering, spreading redness or new dark patches

Things to know first

• Redness, swelling and tiny scabs are expected after spot treatment
• Post-inflammatory darkening can occur, particularly on darker skin or with sun exposure
• Pigment may return, and melasma in particular may relapse
• Pregnancy, active infection, recent tanning and a history of poor scarring call for caution
• Results vary by person, and several sessions may be needed

What to check before booking pico laser in Gangnam

Ask first which picosecond system and which handpiece will be used. The catalog lists several, including PicoSure, PicoWay and Discovery Pico, and they differ in wavelength and options. A treatment label alone does not tell you whether you are getting pigment work, toning or a fractional resurfacing mode. A clinic should name the device and explain why that mode matches your concern.

Ask who plans and performs the treatment. Pigment is one of the areas where diagnosis counts, since melasma, sunspots and certain lesions call for different settings, and some marks should be examined before any laser touches them. If a mole or patch looks unusual, a responsible doctor will say so and may suggest a different path. Ask also whether a test spot is offered for darker skin.

A clear quote lists the device or mode, the number of sessions, any numbing and any ointment or dressings, and follow-up. Be cautious of promises that pico always clears skin or that no downtime applies to every mode. A calm consultation explains that spot treatment may leave scabs for a few days and that sun protection is part of the plan.
