Infrared and Broadband Light for Skin Aging

September 11, 2019 updated by: Anne Chang, Stanford University

Augmentation of Skin Aging Reversal By Broadband Light With Skin Tightening Properties Via Gene Expression Analysis

In this exploratory study, we hope to learn if treatment of broadband light with infrared light can alter the molecular pathways associated with aging. Secondary exploratory objective is to see if there are any visible effects of this light treatment on human skin.

Detailed Description

Studies in model organisms suggest that aged cells can be functionally rejuvenated, but whether this concept applies to human skin is unclear. Recently, we applied 3'-end sequencing for expression quantification ("3-seq") to discover the gene expression program associated with human photoaging and intrinsic skin aging (collectively termed "skin aging"), and the impact of broadband light (BBL) treatment. We found significant changes in 2,265 coding and noncoding RNAs, of which 1,293 that became "rejuvenated" after BBL treatment, whereby they became more similar to their expression level in youthful skin. Rejuvenated genes (RGs) included several known key regulators of organismal longevity and their proximal long noncoding RNAs. Hence, BBL treatment can restore gene expression pattern of photo-aged and intrinsically aged human skin to resemble young skin.

However, the duration of these effects and the potential to augment these effects through increases in particular wavelengths of light have not been explored. The Sciton SkinTyte (800-1800nm) is the ideal technology to examine these questions, since this device has been used in the clinical setting to reduce cheek and submental laxity (Gold, 2010). It incorporates the broadband light technology with an emphasis on 590 nm filter to achieve these clinical results.

This study will be conducted in accord with Declaration of Helsinki principles. After Institutional Review Board approval and informed consent is obtained, six female participants over the age of 55 years will undergo BBLST treatments to the left forearm. Inclusion criteria included Fitzpatrick skin type II or III, and a global assessment of forearm skin aging consistent with moderate or severe forearm skin aging (modified validated instrument from McKenzie et al., 2011) for treated participants. Treatments will be performed on the Sciton Joule Platform using BBL in Skintyte mode with 590ST filter. On a separate part of the arm that is clearly marked, Skintyte alone will be applied. Untreated areas will also be marked. All markings will be photographed. The same investigator will perform the treatments at 4-week intervals for a total of 3 treatments. At each treatment session, two or more passes were performed. Four weeks after the third BBL treatment, 4 mm skin biopsies will performed by Keys punch technique from the BBLST treated, ST treated and adjacent untreated skin. These specimens will be bisected and placed into either RNAlater (Ambion Cat# AM7022) or formalin solution for with H&E, von Giesen or PAS staining.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Genes With Significant Change in Gene Transcription
Time Frame: 16 weeks
The endpoint consisted of clinical inspection of biopsies of untreated skin and skin after three treatments. Genes were considered altered if a statistically significant change in transcription of an individual gene was observed between the treated and untreated skin (significance was set at p<0.01, adjusted for false discovery rate). The values in the table represent the total number of recorded genes with significant change.
16 weeks
