Pixel laser is a brand-new cosmetic concept of laser medicine, which transforms the traditional laser emission mode into pixel mode (microporous mode), and divides each pulsed laser into nearly one hundred micro-laser pulses, with each micro-laser spot of only 75-100 um. When these tiny laser beams are applied to the surface of the skin, the densely-distributed dots look as if they were imaged “pixels”, hence the name. “Therefore, it is named. The risks of the procedure are as follows: 1, redness and swelling of the skin: the skin will be red and swollen on the day of treatment, which will disappear naturally within 24 hours; 2, scabs: very thin scabs will appear on the original part after treatment, which will usually fall off after 5-7 days, and the scabs will fall off naturally, so don’t pick the scabs with your hands randomly, to avoid scars; 3, pigmentation: temporary pigmentation or hyperpigmentation occurs in individual patients after treatment, which will generally return to normal gradually; 4, pigmentation: temporary pigmentation will occur after treatment, which will generally return to normal. Pigmentation: temporary pigmentation loss or pigmentation occurs in individual patients after treatment, generally will gradually return to normal, the time varies from person to person; 4, scar proliferation: individual energy is too large to cause skin injuries caused by burns resulting in scar proliferation. On the whole, this technology is characterized by non-invasive or minimally invasive, and the recovery period after treatment is shorter, which is a more ideal and safe means of treating all kinds of scars. The next day after treatment, you can wash your face and put on makeup, but you should try to protect the scabbed area, don’t swim, sauna and excessive exercise within one week after treatment, pay attention to sun protection after the scabs fall off, and apply topical ointment according to the instructions of the doctor.
