diffuse reflectance spectroscopy
大体时间:Baseline- immediately after irradiation to assess immediate pigment darkening
|
Diffuse reflectance spectroscopy is a non-invasive objective measure of pigmentation based on reflectance patterns of the irradiated skin
|
Baseline- immediately after irradiation to assess immediate pigment darkening
|
|
photography
大体时间:Baseline-immediately after irradiation to assess immediate pigment darkening
|
Cross polarized photography is used to document pigmentation non-invasively and reduce surface glare of the skin.
|
Baseline-immediately after irradiation to assess immediate pigment darkening
|

|
The investigator's global assessment score is a non-invasive subjective measure of pigmentation in which investigators assign a value ranging between 0, corresponding with no hyperpigmentation, to 5, or severe or dark hyperpigmentation.
