Introduction to Pico lasers
Pico laser or “picosecond laser” is a type of laser technology that works in picoseconds, delivering laser light energy in one trillionth of a second. It is considered to be an improvement on the Q-switched laser which is a nanosecond laser that operates with one billionth of a second pulse duration.
In order to tackle pigmentation, Pico lasers deliver pulses of energy directly to the skin tissue which will then create a “photoacoustic” impact. This causes the pigments to break up and shatter into tiny particles that can be eliminated easily and naturally by the body’s immune system.
Why does the picosecond speed matter
Compared to earlier lasers, having extreme speed for Pico lasers means faster time in releasing light energy that will reduce the risk of damaging surrounding skin tissues.
The ability to limit heat damage precisely to the targeted area leads to efficacy in treating pigmentation with lower chances of developing hyperpigmentation1. Less heat also means less discomfort.
With an ultra-short pulse duration, Pico lasers get to deliver higher energy laser beams, allowing pigment fragments to be cleared faster and more effectively with fewer treatment sessions. In one study, it was observed that a group of Asian patients had achieved “faster and better clearance rate” when using picosecond lasers for melasma as compared to Q-switched lasers2.
More than just a laser for pigmentation
Picosecond lasers excel in removing pigmentation as well as tattoos. But they can also be effective in treating skin texture problems such as wrinkles, acne scars and other types of facial scarring.
The treatment process stimulates elastin and collagen growth in the deeper layers of the skin. As a result, this increases tissue density and elasticity to improve and even out the skin texture, giving a much refreshed and rejuvenated complexion. So if you have more than one skin concern, Pico lasers can intensively target various skin issues in skin tone, textural improvements and more to deliver optimal results.
