Summary
The goal of this clinical trial is to determine the sensitization (contact allergy) potential of the test product ColActive Plus Collagen Matrix Dressing after a skin prick test on the skin of healthy human subjects. The main question it aims to answer is:
• Does the product induce any sensitization (contact allergy) after a skin prick using a UniTest PC (pain control) device in healthy human subjects? Participants will have the test product and both positive and negative controls applied, and skin response will be evaluated by an allergist at 15 minutes, 6 hours, and 24-48 hours post-application to see if sensitization occurs.
