Visible Light Study
NCT02663921 · View on ClinicalTrials.gov ↗
Study Summary
The purpose of this study is to learn more about the potential effects of visible light on the skin. More specifically, this study will examine whether an incandescent lamp (light bulb) or LED light bulb can cause skin to become darker. Investigators will determine the minimum threshold dose required to achieve immediate pigmentation darkening (IPD), persistent pigmentation darkening (PPD), and delayed tanning (DT) for Fitzpatrick skin types IV - VI utilizing two visible light sources.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT02663921
The ClinicalTrials.gov registry entry for NCT02663921 describes a study currently listed as completed. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 8 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is NYU Langone Health, which has 1,204 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with Skin Disease appearing as the primary indexed condition, and to 2 interventions — of which Part A: Baseline-Week 2 is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT02663921 reports 1 study location spanning 1 distinct geographic area — top geographies include New York. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll. Verify current status, eligibility criteria, and contact details directly at ClinicalTrials.gov, and discuss any participation decision with your own healthcare provider.
