The protective mechanism of
the skin is expressed in still another way, namely, the release of skin pigment
(melanin) to protect against injury to the skin from strong doses of sunlight.
In the white races, which have comparatively little skin pigmentation,
exposure to sunlight increases the amount of pigment produced by the
specialized Malpighian cells. The result is a coat of sun tan. The tanning is
caused by the invisible ultraviolet rays from the sun. The coat of tan
disappears as the more highly pigmented cells die and move toward the surface
of the skin.
The development of
additional skin pigment under the influence of sunlight is not an
instantaneous process. The attempt to get a coat of tan too quickly, therefore,
usually re burn like any other and should be treated accordingly. It can be
serious.
The right way to get a sun
tan is to limit your exposure at first and gradually increase the amount of
time spent in the direct sunlight. If you know that you do not tan, because
your skin is light-sensitive, avoid exposure.
Freckles are produced by
the same mechanism as skin tanning. In this case, however, the areas of
increased pigmentation are spotty instead of consistent.
Cosmetics
Cosmetics are
beauty aids. Since the search for beauty is a universal and perennial pastime, the history of cosmetics
stretches back into remotest antiquity and may be expected to be reformulated
in all future generations. Today in the United States cosmetics are big
business. Well over a billion dollars a year is now spent annually on all varieties of cosmetic
preparations, including soaps, shampoos, hand lotions, and the like.
From the
standpoint of mental health, the increasing use of cosmetics is probably justified. The pursuit of
beauty is a legitimate aim of civilized life. The woman who does
not use cosmetics today stands starkly apart from her "sisters under the
skin." It is not uncommon to hear a woman say, "I feel positively
undressed without my lipstick."
The people in the cosmetics
business know all this and they say, "We don't sell merchandise, we sell
illusion." The danger in this is that many cosmetic preparations are
over-enthusiastically promoted and overpriced. Women are repeatedly cozened to
expect miracles from cosmetics, and those miracles never happen.
Cosmetics are not and can never be a
substitute for good health. There is no way to "nourish" the skin by
creams or lotions or falsely labeled "skin foods" applied from the
outside. The skin is nourished, like all body tissues, through its own blood supply. False and
misleading names are applied to many cosmetic products. You ought to know that
there is no known substance or combination of substances that can live up to
the promises suggested in any of the following names: contour cream,
crow's-foot cream, deep pore cleaner, enlarged pore preparation, eye wrinkle
cream, miracle oil, nourishing cream, pore paste, rejuvenating cream, scalp
food, skin conditioner, skin firm, skin food, skin tonic, eyelash grower,
wrinkle eradicator, spot reducer, bust developer, bust reducer.
No better
cleansing agent than ordinary soap and water has yet been developed. Frequent
bathing rather than the use of any special kind of soap is the best way to
prevent body odor. On the other hand, too frequent bathing can be harmful to
the skin and may occur as compensation for guilt feelings. Skin deodorants and
antiperspirants are not objectionable, but they are by no means as important
to social success as the advertisements make them out to be.
