Working principle

According to the principle of selective photopyrolysis, when shorted the action time of the laser, the laser energy diffuses less to the surrounding tissue. If the energy is limited to the target that needs treatment, the surrounding normal tissue can be protected, so the selectivity of treatment become stronger.The picosecond laser pulse width is only 1% of the traditional Q-switched laser. Under this ultra-short pulse width, the light energy is too late to be converted into heat energy, and there is almost no photothermal effect.When the laser energy is absorbed by the target, its volume will expand rapidly, and then be blasted and torn into pieces. "The picosecond laser is more powerful and complete in crushing pigment particles and less damaging the surrounding tissue." From the perspective of treatment, the effective rate can reach more than 94% (Ota nevus almost 100%).

Operation Steps

1、Clean the treatment area, if you have hair, you need to remove it

2、Apply anesthetic cream as needed

3、Disinfect the treatment area

4、Adjust the treatment parameters according to the parameter table

5、All treatments are recommended not to break the skin or ooze blood, which can greatly reduce the risk of melanin deposition, and the number of treatments will increase accordingly.

When starting treatment, use low frequency first (let the machine warm up first to reduce the damage to the machine), and slowly close to the skin to continuously emit light. Then slowly raise up to find a suitable distance to start treatment. After a few minutes, you can increase the frequency. When you start treatment, you must first get close to the skin to continuously emit light, and then slowly raise the treatment head, so as to avoid the sound from scaring the patient It can also find the best treatment distance. When the blasting sound is the loudest, it is when the energy is focused. In many cases, the focused energy is not used, because the focused energy will bleed, and the probability of coloration is very large. Generally 2 minutes after treatment The skin will flush and the effect is best. Focusing on energy: The point with the greatest energy can be judged by listening to the sound, and the point where the sound is the loudest and the most brittle can be understood by beginners.

6.It is recommended to use repair products and products that inhibit pigmentation after treatment

7.After treatment, you must enter physical sunscreen, masks, umbrellas, etc.

8.The general treatment interval is about one month, the parameter table has the recommended number of treatments, and the doctor determines whether to add treatment according to the patient's recovery.
