Brief summary
This IIa study with intraindividual comparison of treated versus untreated to assess the wound healing efficacy of Tyrosur® Gel after experimental impairment of the skin using an abrasive wound healing model.
Detailed description
This is a single-center, randomized, observer-blind phase IIa study with intraindividual comparison of treated versus untreated to assess the wound healing efficacy of Tyrosur® Gel after experimental impairment of the skin using an abrasive wound healing model. In the investigation two small, superficial, abrasive wounds will be induced on the right forearm and one on the left forearm of each subject using a sterile surgical hand brush. These wounds will then be treated with the investigational products. The wound healing will be clinically assessed and photographs will be taken for documentation.
