In the test, two symmetrical lesions were removed from each subject’s upper chest, on opposite sides. As Mederma should only be applied after a wound has healed; each subject was allotted 2-3 weeks healing time and then reported back to the research center to receive random assignments placing them in either a treatment group or no-treatment group. According to the investigator of this study, 77% of subjects noted moderate to significant improvement overall on scars treated with Mederma over untreated scars at week 10.
Mederma, which was launched by Merz Pharmaceuticals in 1997, is available in food, drug and mass retailers in 20- and 50gram tubes. Merz has recently introduced Mederma Cream + SPF 30.
