Piezoelectric Drived Microneedling in Treating Refractory Skin Diseases: A Pilot Study
Piezoelectric drived microneedling treats refractory skin disorders using hollow microneedles assisted by ultrasound. Mechanically, the injection of medicine by hollow microneedling could makes the distribution of medicine more evenly. And the addition of ultrasound technique improves the effectiveness of microneedling. Investigators plan to conduct a pilot study to investigate the efficacy of using piezoelectric drived microneedles in treating refractory skin diseases.

Investigators accept participants of hypertrophic scar, keloid and warts. For participants who are not candidates for traditional surgery, investigators will consider to accept carefully.
