Stretch Marks on Abdomen

Study Overview
=================
Brief Summary
-----------------
The primary objective of this study is to determine the effect of Stratacel® wound dressing on cosmetic outcomes following 1064/532nm picosecond laser (Picoway®, Syneron Candela Corp, Wayland, MA, USA) treatment of abdominal striae alba. Secondary objectives include examining the effect of Stratacel® wound dressing on post-laser healing and symptomatology.

Detailed Description
-----------------
Twenty adult subjects with abdominal striae alba will be enrolled. All striae will be treated using the 1064/532nm picosecond laser with designated and standardized settings (Appendix A). The abdominal striae treatment region will then be split across the body vertically with one half randomized to Stratacel® and the other to placebo, clear ultrasound gel (Aquasonic). A blinded study coordinator will apply the products to each randomized half-abdomen immediately following laser treatment. A total of 3 treatments will be completed at 1 month intervals. Blinded-investigator and subject self-assessments will be performed at post-treatment days 2, 5, 7, and 10 after each laser session. Assessments will also be performed 1 and 3 months after the final laser treatment.

Any planned surgical or cosmetic procedure in the treatment area during the course of the study. Any UNCONTROLLED systemic disease -a potential patient in whom therapy for a systemic disease is not yet stabilized will not be considered for entry into the study. Significant history or current evidence of a medical, psychological or other disorder that, in the investigator's opinion, would preclude enrollment into the study. Red or brown colored striae in the intended treatment area. Active dermatitis, open wound, active bacterial, neurologic, fungal, or viral infection in the proposed treatment area. Inability to ambulate following the procedure. History of skin tightening or other treatment in the striae region in the preceding 12 months before study enrollment and for duration of the study. Use of topical retinoids, hydroquinone, medicated cleansers, cellulite creams, or steroids to the treatment area within the preceding 2 weeks and for duration of the study. Allergy to any ingredient in the study medication or placebo. Current participation or participation within 30 days prior to the start of this study in a drug or other investigational research study.
