Scrubbing brushes and skin brushes of all sorts should be used even more sparingly than soap or hot water, for the same reason.

Nature did not coat us over with either boards or rubber, but with delicate, velvety, sensitive, living skin worth ten times as much as any sort of leather, bark, rubber, or cloth, for resisting cold, heat, and injuries.

It is most important for the health of the skin that we keep that velvety coating unscratched and unbroken.

The use of brushes and bristles of all sorts, therefore, should be chiefly restricted to the hair and the finger nails, as for every ounce of dirt that they take out of the skin, they do a pound of damage to it.

They scrub off the delicate epidermis, as well as the natural oil in it, and leave it dry and irritated and ready to crack open.
