What is a picosecond laser and what is it used for?

It is a laser device that emits pulses of light energy lasting 10-12 seconds. The main utility of the picosecond laser is the treatment of pigmented lesions (lentigines, freckles, melasma) and tattoos. However, using picosecond lasers with a diffractive lens, it is possible to separate the energy into different beams and stimulate the production and rearrangement of collagen in the dermis. It is precisely this effect that can be beneficial in improving collagen disorders such as hypertrophic scars and keloids.

Picosecond laser is mainly applied in the treatment of pigmented skin lesions such as body tattoos, eyebrow tattoos, eyeline tattoos, lip line tattoos and trauma tattoos. The picosecond laser can greatly shorten treatment times as well as being faster and safer. Although a tattoo can be completely erased, in laser tattoo removal we must bear in mind that yellows, greens and oranges are the most complicated colors to remove, so we will need more sessions than for a completely black tattoo.
