Clinical Trial Summary

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.

Description:

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Short-term response	This is a qualitative item which should be evaluated by comparing the general images and dermoscopic images pre-treatment and post-treatment carefully.	1 week after treatment
Primary	Long-term response	This is a qualitative item which should be evaluated by comparing the general images and dermoscopic images pre-treatment and post-treatment carefully.	1 month after treatment
Secondary	Pain score during treatment	Using visual analogue scale (score 0-10, 0=no pain, 10=unbearable pain) to evaluate the level of pain	Immediately
Secondary	POSAS(The Patient and Observer Scar Assessment Scale) score	A widely used scar scale for evaluating the severity of scar by both patients and dermatologists. Score ranged from 11 to 110. The higher score means severer condition of scar.	1 month after treatment
