For example, over the top of stitches beneath your skin (subcutaneous stitches) or to close an incision made during an operation.

Definition of ozone for English Language Learners. : 1  a form of oxygen that is found in a layer high in the earth's atmosphere. : 2  fresh healthy air especially near the sea.
Ozone is a gas that is present in the ozone layer in the stratosphere of the Earth. 1  There, it will absorb almost all ultraviolet light which is harmful to many organisms. The term Ozone depletion can refer to a number of distinct, but related phenomena: Since about the 1970s, there has been a decrease in total volume of the Ozone in the ozone layer, of about 4%, per decade. There are seasonal variations in the ozone layers; in springtime, there is less ozone in the ozone layer over the polar regions, esp. the south pole. This is generally known as ozone hole. In addition to these well-known stratospheric phenomena, there are also springtime polar tropospheric ozone depletion events. The details of polar ozone hole formation differ from that of mid-latitude thinning, but the most important process in both is catalytic destruction of ozone by atomic halogens.
