A microneedle device includes a device body supporting a number of microneedles. A protective cover assumes a closed state in which it protects the microneedles against inadvertent contact and an open state in which the microneedles are exposed. The device body and the protective cover are configured such that, for at least part of a motion from the closed state towards the open state, the protective cover is guided by mechanical engagement with the device body configured to prevent impact between the protective cover and the microneedles, at least until the protective cover has cleared an impact risk region around the microneedles.
