Dermatization is to directly remove a scar and other hyperplasia at the specific growth or hyperplasia of the skin through a certain machine, so it is called dermabrasion. This technology mainly uses the grinding wheel or drill bit of this machine to directly remove the tissue of the protruding part by mechanical means. Generally, this kind of machine is a bit like a dental drill, which directly grinds off some hyperplastic tissue parts protruding from the skin surface, but generally the grinded part cannot exceed the superficial dermis of the skin. It is usually used for the treatment of scars, and sometimes it can also be used for the treatment of other skin tumors, especially benign skin tumors, and of course it can also be used for the treatment of tattoos.
