The following is a friend's experience: Remind a friend who wants to go to Shanghai No.9 Hospital to do laser registration, and it is best to do it during the internship, because none of the registration is done by herself, but has been pushed to her team, which is composed of junior assistant nurses without medical skills and medical ethics.
In particular, a female assistant of Dong's team (that is, the ugly woman who usually sits opposite Dong and writes medical records by hand) is the scum of the medical profession. She treated the patient in a perfunctory way and swore. My buddy hung up the registration fee for the expert who needed acne printing, and the result was pushed to the woman. The woman casually scanned it and said it was done.
Precautions:
Dot-matrix laser acne printing can penetrate deep into the skin where Propionibacterium acnes is located. Photothermal energy is aimed at Propionibacterium acnes, which takes effect quickly, stimulates the proliferation of endogenous lymph, and quickly kills Propionibacterium acnes in the skin. Normal skin tissue is not destroyed, so it will not leave scars. So as to integrate the two-way functions of removing acne and scar, and the effect of treating acne is more perfect.
