The PicoSure laser is a picosecond device that uses extremely short pulses of light energy in trillions of a second, also known as picoseconds. Unlike lasers that rely on intense heat energy, PicoSure is a gentler treatment that flashes small bursts of energy deep within the skin to target damaged tissue without harming the surrounding skin. The result is healthier, visibly clearer skin with minimal downtime and discomfort and with fewer treatments.
