Topical Centella Asiatica and the Cosmetic Appearance of Stretch Marks

University of California, Davis15 enrolled

Overview

The purpose of this study is to clinically evaluate the efficacy, safety as well as patient satisfaction in the use of topical Centella asiatica (CA) on the cosmetic appearance of stretch marks.

Subjects with abdominal stretch marks will be enrolled in to this study. The presence of abdominal stretch marks will be confirmed by a board certified dermatologist. The right and the left side of the abdomen will be randomized by binary randomization to treatment with CA cream or the vehicle cream. Therefore each patient will serve as their own control. Each half of the abdomen will be subjected to topical treatment with CA 1% Cream formulated in PCCA Lipoderm® base or PCCA Lipoderm® base as the placebo vehicle treatment based on prior randomization. The creams will be given to the patient in blinded fashion: Cream A (containing CA) and cream B (vehicle/placebo) with instructions apply both formulations daily at night. Patients will be asked to return to clinic at 6 weeks and 12 weeks for follow up assessment for a total of 3 sessions (baseline, 6 weeks, 12 weeks). High-resolution digital photographs of the stretch marks will be taken at baseline and at each follow-up visit to document clinical response. Two physician graders blinded to the photographs and the treatments will assess cosmetic outcome on a six-point analog scale The width of the treated stretch marks in each subject will also be measured at the baseline and 8 weeks after the final treatment. The difference of the width will be converted into the percentage of reduction from the baseline. Subjects will also be asked to complete two surveys at each visit. The two surveys include patient satisfaction with cosmetic and clinical outcome based on a five-point scale.

Outcomes

Primary Outcomes

Cosmetic Outcome- Fraction Improving by at Least 1 Point Increase in Overall Appearance of Stretch Marks

Assessed by four blinded evaluators by observing comparative baseline photographs using 6 point scale (worsened = -1 points, no improvement = 0 points, mild = 1 points, \<25% improvement, moderate = 2 points, 26-50% improvement, good = 3 points, 51-75% improvement, excellent = 4 points, \>75% improvement)

Time frame: 12 weeks

Stretch Mark Width/Area

Stretch mark width: measured at week 12. This will be converted into the percentage of reduction from the baseline.

Time frame: 12 weeks
