I have played in this Shanghai Merrick Plastic Surgery Hospital, and the price is also affordable. Experts also introduced me to the whitening needle, which can be used to
Improve dull skin, spots and scars. Although the effect is not as obvious as phototherapy, it has no side effects and will not turn black.
Regular use can also take effect quickly and clearly, without feeling "very painful" like phototherapy, and it can only be effective in the treatment area.
A dozen can be effective all over the body.
