At least, unlike many other similar products, tissues generally are quite quickly biodegradable, and virtually all such "pulp paper" products (including common newsprint) are made almost entirely from "new growth" farmed trees which can be considered a renewable resource.

One might question whether the fuel cost of boiling your hanky consumes more non-renewable resources than making of the tissues that replace it for one use-and-wash cycle; but it would require some realistic and accurate data, and some hard thinking, to be sure.

It's not always obvious that the obvious isn't as obviously right as might seem obvious.
