Abstract

Tretinoin is often prescribed before laser resurfacing in an attempt to enhance results. We sought to assess the clinical and biochemical effects of preoperative tretinoin use before laser resurfacing. Patients were randomized to apply tretinoin to one forearm and placebo to the other for 3 weeks. Patients' photodamaged forearms were focally treated by carbon-dioxide laser resurfacing. Biopsy specimens were obtained at baseline and various times posttreatment. Real-time polymerase chain reaction technology was used to quantify messenger RNA levels of types I and III procollagen and matrix metalloproteinases-1, 3, and 9. Wounds were assessed for degree of re-epithelialization using a computer graphics-generated template. A colorimeter was used to quantify postoperative erythema. No substantial differences in either biochemical markers or clinical end points were identified between tretinoin and placebo pretreated forearms. We found no evidence of enhanced collagen formation, accelerated re-epithelialization, or quicker resolution of postoperative erythema with tretinoin pretreatment before laser resurfacing.
