Official title

Safety and Efficacy of 2910 nm Fiber Laser Resurfacing and Laser-Coring Treatment to Lift the Eyebrow, Submental Lax Tissue and Address Advanced Signs of Facial Aging

Overview

The primary objective of this clinical trial is to evaluate the safety and effectiveness of the 2,910 nm mid-infrared erbium-doped fluoride fiber glass laser (UltraClear, Acclaro Medical) for non-invasive dermatological aesthetic treatment of three facial regions: eyebrow lift (Region 1), submental tissue lift (Region 2), and improvement of rhytids and skin laxity in the cheeks, midface, and jawline (Region 3).

Interventions

• Device 2,910 nm mid-infrared erbium-doped fluoride fiber glass laser (UltraClear, Acclaro Medical)
  Enrolled subjects will receive a series of two with an optional third 2,910 nm Fiber Laser treatments using fractional ablative resurfacing modes, laser-coring and full ablation addressing the full face and upper neck.

Primary outcome measures

• Objective measurement of maximal eyebrow lift according to quantitative 2D imaging. [Time frame: Six months following final treatment]
• Blinded Photographic Review [Time frame: Six months following final treatment]
• ○ Objective measurement of lax submental tissue lift according to quantitative 2D imaging. [Time frame: Six months following final treatment]

Secondary outcome measures (2)

• Physician rating on the Global Aesthetic Improvement Scale (PGAIS) [Time frame: Six months following final treatment]
• Subjects rating on the Subject Global Aesthetic Improvement Scale & Satisfaction Questionnaire (SGAIS) [Time frame: Six months following final treatment]
