Official Title: Determination of the Minimal Dose of Visible Light Required to Achieve Immediate Pigment Darkening, Persistent Pigment Darkening, and Delayed Tanning for Fitzpatrick Skin Types IV-VI Utilizing Two Vis

Brief 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.

Current Primary Outcome:

  • Diffuse Reflectance Spectroscopy (DRS) to examine the optical properties of melanin and deoxyhemoglobin [ Time Frame: 12 weeks ]
  • Quantification of the scattering and absorption properties of the skin in which the beam of light will penetrate using DRS [ Time Frame: 12 weeks ]
  • Measurement of pigmentation changes induced by the two light sources using diffuse reflectance spectrometer [ Time Frame: 12 weeks ]
  • Measurement of pigmentation changes induced by the two light sources using Colorimetry [ Time Frame: 12 weeks ]
  • Measurement of pigmentation changes induced by the two light sources using Cross-Polarized Digital Photography [ Time Frame: 12 weeks ]


Original Primary Outcome: Same as current
