Skin troubles are of two main kinds according to their cause: _internal_, due to the irritation of waste-poisons, or toxins, in the blood; and _external_, from direct injury or irritation of the skin from without.
The latter are often due to the wearing of too tight or too heavy clothing, or the failure properly to wash, cleanse, and ventilate the skin.

Some of the lesser disturbances come from the chafing of collars, wristlets, and belts, and are, of course, relieved by loosening the clothing or substituting soft, comfortable cotton for rasping flannels.
Others come from the use of too strong soaps, or the too frequent use of hot water, or too vigorous scrubbing of the skin, and these can be relieved by the avoidance of their cause.
Sunburn and Freckles and how to Cure Them.

Upon the hands and face, sunburn and freckles may occur from exposure to the weather.

They are not caused necessarily by exposure to direct sunlight; as the bright light and the cold air out of doors, also, will produce this irritating effect upon the skin.
The best way to cure sunburn is to bathe in cool water, take a night's rest, then go out the next day, and the day after, and take another dose of exposure, keeping this up until your face is hardened to stand a reasonable amount of sun.

If you are in proper condition, neither your face nor your hands will sunburn uncomfortably.
