1. What is picosecond?
Picosecond itself is a unit of time.
In laser diagnosis and treatment, it refers to a laser diagnosis and treatment device with a pulse width (when the energy is constant, the sending time of a laser pulse) of picoseconds.
Of course, the picosecond laser is not only used for the diagnosis and treatment of skin diseases, but also for the treatment of other diseases, and even industrial laser drilling.
So, don’t think that this thing is specifically used to treat skin diseases just because it has a skin word.
2. How does it work?
Take the common pigment treatment in laser diagnosis and treatment as an example:
The basic principle of picosecond laser diagnosis and treatment is to use laser light to selectively and directly bombard the pigment block on the basis of not harming the skin tissue as much as possible, and use photothermal and photomechanical reaction to break it, and the fragments will be caused by macrophages in the body. Package and eliminate.
Moreover, the difference between picosecond laser and traditional laser diagnosis and treatment (Q-switched nanosecond laser) is:
Picosecond laser is extremely fast and requires less energy to achieve the therapeutic effect. When the bombarded target does not even have time to produce too much photothermal reaction to destroy the surrounding tissues, it will be “shattered” by the photomechanical reaction. (“Light shock” is often heard)
Therefore, the picosecond laser is faster, stronger, less painful, and the treatment cycle is shorter.
Seeing this, are you all eager to try?
Don’t worry, the fun is yet to come.
3. What situations can be handled?
Picosecond laser has a wide range of clinical applications. Below are some examples of skin diagnosis and treatment.
The performance of picosecond laser in the treatment of tattoo removal is very gratifying.
Compared with traditional treatment, it can handle complex tattoos, while traditional laser treatment is not ideal for complex tattoos other than black.
The important thing is that the pain difference is very obvious (10/10, nanosecond is 7.9, picosecond is only 3.8).
4. Adverse reactions.
After laser treatment, there is a certain degree of chance of adverse reactions.
For example: edema, erythema, uneven skin tone, temporary anti-melanization, etc.
Edema and erythema are common reactions in treatment, and most of them will subside after 1-2 days of observation.
Uneven skin tone is a common phenomenon in picosecond freckle removal. Mixed spots generally require multiple treatments, and the uneven skin tone after a single treatment will subside in subsequent treatments.
All in all
Seconds are not fragrant? To be honest, the scent is quite fragrant.
However, through the popular science mentioned above, I believe everyone knows that picoseconds are only an updated iteration of medical technology and methods. As a tool, it is not omnipotent. It requires people who are familiar with the tool to perform specific operations.
In the face of different diseases, picoseconds is just one of the treatment methods, not necessarily the best.
In the face of picosecond hype and crazy planting, we must be calm and rational.
wants to be a student of picoseconds, because of the friendliness of the wallet, it can be divided into very cold areas.
