OBJECTIVES
Striae distensae are linear atrophic dermal scars. Despite several currently available therapeutic modalities, no consistently effective therapies have been established. This study aimed to evaluate and compare the efficacy of topical recombinant human epidermal growth factor (rhEGF) and ablative fractional carbon dioxide (CO2 ) laser (AFXL) versus ablative fractional CO2 laser and topical Aloe vera gel in treating striae alba.METHODS
A total of 24 participants with striae alba were enrolled. Patients' striae were divided into the left and right sides. Participants were treated with fractional CO2 laser on both sides for three sessions at 4-week intervals. Immediately after the laser treatment, each side of the striae was randomly assigned to either rhEGF or Aloe vera gel treatment. Patients were required to apply the medication twice daily up to 1 month after the last laser treatment session. Texture, average melanin, and melanin variation were assessed at pretreatment, 1 month after the first, second, and third treatments, and 6 months after the last treatment. Participants were asked to complete a self-administered questionnaire. Nine participants underwent skin biopsies of the nontreated and treated striae, which were obtained from each treated side.
