简要总结
To demonstrate the safety and performance of the Tixel fractional system for treatment of photodamage using low-energy settings.
详细描述
A Prospective, single-center, single-arm clinical study of subjects who are seeking a procedure to reduce the appearance of photodamage, and meet study eligibility criteria, and have provided informed consent will be enrolled in the study. One investigational center will participate in the recruitment. Each study subject will receive 3 treatments with Tixel at 4-6 week intervals. Final follow-up will occur 3 months following the last treatment

排除标准

- •a cosmetic procedure to improve rhytides (i.e. Carbon Dioxide/Erbium/similar laser/fractional resurfacing, radiofrequency treatment) within 3 months
- •prior facial treatments with laser, surgical, chemical or light-based facial treatments within the previous 3 months, including botulinum toxin injections or microdermabrasion.
- •Injectable filler in cheeks (mid face) temples and in the upper face area to be treated within 3 months of investigation.
- •Any subject who has visible scars or other visible changes over the treated areas that may affect evaluation of response and/or quality of photography.

- •Collagen vascular or bleeding disorder
- •Immunosuppression or autoimmune disease
- •Active acne vulgaris, herpes simplex virus or any existing skin condition/disease that in the investigator's opinion would interfere with the evaluation of the safety of the study treatment and evaluation.
