1. WHAT IS THE TANNING PROCESS?
A. UVB (from the sun or in a low pressure indoor tanning unit)
stimulates the melanocytes in the upper skin layer (called the epidermis) which then produce melanin. UVA then darkens the melanin,
thereby giving the skin a dark appearance. A tan gradually fades as the skin cells migrate to the surface.
2. WHY
DOES A TAN DISAPPEAR?
A. The "tan" or pigmentation process, occurs in the epidermis, the top skin layer. The epidermis replaces all its skin cells every 28-30 days. Cells in the inner portion of the top skin layer divide themselves,
migrate to the surface, gradually die and slough off. Skin cells contain melanin, and as a result of UV exposure, rise to the
surface and flake off. Therefore a tan can be maintained only by repeated exposure to UV light.
3. HOW OFTEN IS A
PERSON ALLOWED TO TAN?
A. Since 1986, the Food and Drug Administration guidelines suggest that a 48
hour time interval should pass between tanning sessions. Pigmentation and/or erythema (sunburn) may not be fully visible for
between 12-24 hours. Thus two tanning sessions within this 24 hour period could cause an unintentional burn. In general,
maximum pigmentation can be built up gradually, following the exposure schedule, in 5-10 sessions.
4. WHY SHOULD I TAN?
A. Sunlight is absolutely essential to all life on earth. There are various reasons, both biological and psychological,
why exposure to light is desirable. In addition, many people believe they look better with a tan...healthier, thinner and more
defined. Thus, having a tan may provide a psychological uplift for some. There have been numerous studies attributing
UV light as beneficial for certain cancers, psoriasis, skin conditions, seasonal effective disorder (SAD), stimulating Vitamin D in
the skin, etc... but according to the Federal Trade Commission, working with the Food and Drug Administration, no claims or advertisements
can be made regarding the relative safety of indoor tanning or any of its possible benefits. It is up to the consumer to research
any possible benefits as well as any negative aspects, and make an informed decision by his or herself. Don't let the government
control your right to sunlight!
