Study Description
Brief Summary:
The purpose of this study was to determine whether light emitting diode (LED) therapy can improve skin appearance of human subjects with aged/photoaged skin. A reduction in rhytid depth as well as in skin surface roughness and in the degree of elastosis after LED treatments was expected.

Condition or disease Intervention/treatment Phase
Skin Aging Photoaging of Skin Device: Sham light Device: LumiPhase-R™, OPUSMED Inc. Montreal, Canada Phase 2 Phase 3

Study Design

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 40 participants
Intervention Model: Single Group Assignment
Masking: Single (Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Non-ablative Light Source for the Treatment of Rhytides (Wrinkles)
Arms and Interventions

Arm Intervention/treatment
Sham Comparator: Sham light
one side of the face was treated three times weekly for four consecutive weeks (12 treatments) with a Sham light on the experimental periorbital area
Device: Sham light
Experimental: LED-treated
one side of the face was treated three times weekly for four consecutive weeks (12 treatments) with 660 nm Light emitting diode (LED) on the experimental periorbital area

660 nm wavelength delivered in a sequential pulsing mode


Outcome Measures

Primary Outcome Measures :
  1. Percent Change From Baseline in Microtopographic Profilometry Ra Values (Skin Roughness). [ Time Frame: Baseline and 4 weeks ]
  2. Percent Change From Baseline in Microtopographic Profilometry Rz Values (Rhytid Depth and Severity. [ Time Frame: Baseline and 4 weeks ]

Secondary Outcome Measures :
  1. Change From Baseline in Units on the Fitzpatrick Classification System (FCS) Scale for Degree of Wrinkling. [ Time Frame: Baseline and 4 weeks ]
  2. Number of Adverse Events. [ Time Frame: Adverse reactions were monitored throughout the study and up to 4 weeks. ]
