11. A method of applying a drug reservoir to a treated area of skin with a patch comprising an anchor member, a target member, and a folding member, the folding member comprising the drug reservoir and being attached to the anchor portion through a hinge defined by a line of attachment that is not contiguous with an edge of the anchor member, the target member comprising an opening adapted to enable skin treatment, the method comprising:
