About

To study the effect of fractionated 1927-nm non ablative thulium laser in reduction of post inflammatory hyperpigmentation (PIH) using a validated and reproducible model for studying PIH.

• Determine if there is aa reduction in PIH in patients treated with three (3) monthly sessions of fractionated 1927-nm non ablative thulium laser
• Determine if there is efficacy of post-procedure clobetasol propionate 0.05% ointment in the management of PIH
• Determine the histological and molecular changes that occur with laser and laser plus topical steroid treatment compared to untreated skin

Full description

The design of the study consists of a total of six visits including one initial screening visit within 107-127 days depending on the scheduling of your screening and subsequent visits. Assessments such as visual examination, photography, Investigatory Global Assessment (IGA) of pigmentation and erythema; Colorimetry; and Diffuse Reflectance Spectroscopy of the intended treatment area will be conducted at Visits 1-5. Optional biopsies will be taken at various time points.

Enrollment: 15 estimated patients
