## Abstract

When a device mounted on a mask pack, and a mask pack and a kit including the device are used, the mask pack may be well attached onto an application site, for example, skin; delivery of a bioactive material via the skin may improve; and itching, pain, burning, and erythema that may occur during a process of delivering the bioactive material to the skin may be prevented by using the device including an electrode.

## Claims

### Claim 1

A device mounted on a mask pack, the device comprising:
a reverse electrodialvsis battery; and
an intermediate sheet having an electrically conductive part,
wherein the reverse electrodialvsis battery comprises:
