Fig. 5. Psoriatic plaques improved significantly after 1 week of microneedle patch application. The circle indicated by the white dotted line is a plaque treated with a microneedle patch. The modified psoriasis area and severity index decreased from 7 to 1 in patient 1 (a and e), from 9 to 3 in patient 5 (b and f), from 5 to 0 in patient 6 (c and g) and from 6 to 2 in patient 9 (d and h). These four patients were very satisfied with the additional application of the microneedle patch. Images are reproduced from ref. 54. Copyright(2017) British Association of Dermatologists.
