Background: Trichloroacetic acid (TCA) chemical peel and dermabrasion are beneficial methods for treatment of photoaged skin.
Objective: In this study, we evaluated the changes induced by these therapies on various structures of facial skin of nine dark-skinned patients (Fitzpatrick types IV-V; TCA, five patients; dermabrasion, four patients) demonstrating different degrees of photodamage.
Methods: Routine histopathology coupled with histometric computer-assisted image analysis was used to assess epidermal changes.
