Procedure to apply a microneedle patch to the skin. (A) The subject or investigator picks up the patch and removes the protective cap. (B) The subject forms a fist in the other hand and then the subject or investigator places the patch on the forearm. The subject or investigator pushes on the patch with the thumb and continues to apply force until hearing a ‘click’ sound, indicating that enough force has been applied. (C) The subject leaves the patch on the skin for 20 min, after which the subject or investigator peels the patch off the skin and the investigator saves the patch for additional analysis.
