The sharp instrument you are talking about should be a point scanner, which causes deep wounds and is easy to leave scars after later recovery.
At present, the more mature technologies are photon therapy and position extraction.
The cost of photons is about 4000- 10000 yuan. The advantage is that it can remove spots and make the skin delicate, so photon therapy is also called "photon rejuvenation". Photonic machines are different. You need to find a queen-class machine to get good results.
The cost of local extraction method will be much lower, but the treatment effect is determined by the difference of liquid medicine and the level of operating technicians, and there is also the problem of inhibiting pigment reflux in the later stage-controlling spot regeneration.
Facial skin has a strong ability to recover, and it is not easy to leave scars ~ Freckles can't be eradicated, but it can be guaranteed that your generation will not grow any longer, and your's descendants will continue to grow spots because of genetics. So everyone says freckles can't be eradicated! I wish you success in freckle removal. If you have any questions, you can leave a message in my mailbox, limiao19840813 @163.com.
