Picosecond, generally referred to as picosecond laser, is a type of laser technology.
A picosecond is a unit of time, which is one trillionth of a second. Picosecond laser is the use of laser light with pulse duration at the level of picoseconds to promote the regeneration of collagen fibers and elastin fibers, which can improve skin texture, repair scars and lighten wrinkles.
Picosecond laser has short action time, fast treatment, small thermal damage, relatively short recovery period, small trauma after treatment, and less damage to the dermis.
However, there are certain contraindications to picosecond laser treatment, such as keloid, pigment abnormalities, patients with serious systemic diseases or immune diseases, and patients with coagulation function, all of which are not recommended. Picosecond laser treatment, if improperly operated or improper postoperative care, can lead to local skin pain, infection, pigment abnormalities and other adverse reactions.
Therefore, for patients who have the need for picosecond laser cosmetic treatment, it is recommended to go to regular professional medical beauty institutions to ensure the effectiveness and safety of the treatment.
