An improved wound dressing is provided which comprises a backing layer bearing a reference marking, a hydrocolloid layer and a release layer. The hydrocolloid swells in use. This swelling can be seen or felt through the backing layer. When the swelling extends to or beyond the reference marking, the dressing should be changed to prevent leaking. Thus, the dressing can be left in place for as long as possible, but not so long as to damage the underlying skin.
