What should you know about picosecond laser technology?

The device sends energy into a chosen target, such as tattoo ink or unwanted pigment. The pulse is measured in picoseconds, an extremely short time interval. The rapid delivery can create a photoacoustic effect that fragments target particles, so the body can gradually clear them. Different wavelengths and settings suit different colours, depths, and skin concerns; the device is not one universal treatment.

A qualified clinician should examine the area, identify the concern, and check for factors that may affect healing, including recent sun exposure, active infection, medicines, and a history of pigment changes or raised scars. Ask which wavelength and handpiece are proposed, whether a test area is appropriate, and what the recovery routine involves. Eye protection is required during treatment, and the treated skin should be protected from unnecessary sunlight afterward.

After treatment, seek clinical advice for increasing pain, extensive blistering, spreading redness, pus-like discharge, fever, or symptoms near the eyes. A delayed dark or pale patch should also be reviewed, especially if it is expanding. The technology’s short pulse does not remove the need for careful settings, cooling, hygiene, and follow-up.

Ask what target the laser is addressing, why a particular wavelength is suitable, what change should be expected first, and how progress will be judged. Clarify the likely number of visits for your specific concern without assuming every session will produce the same response.
