An invisible medical skin patch includes a strippable layer 1 having tearing lines 11 and transversely and longitudinally extending lines of perforations 12, medicated patches 2 coated on the strippable layer 1 over the tearing lines 11 and beyond the lines of perforations 12, each medicated patch 2 consisting of an adhesive layer 21 and a medicated layer 22. By means of the lines of perforations 12, the invisible medical skin patch is easily separable into multiple patch units carrying one medicated patch 2. The design of the tearing lines 11 facilitates application of each individual medicated patch 2.
