F.A.Q.
: Why
Does My Tan Fade?
Tanning is part of
what may be referred to as the "pigmentaion process" that
occurs in the top layer of skin (the epidermis). The
epidermis replaces all of its skin cells every 28-30 days.
Those cells in the inner portion of the epidermis divide
themselves, migrate to the surface, then gradually die and
slough off. Skin cells contain melanin, which is darkened as
a result of UV exposure. As the cells migrate to the surface
and flake off, a tan will progressively fade without
repeated exposure to UV light.
Pigmentation and/or
erythema (sunburn) may not be visible for 12-24 hours. Thus,
two tanning sessions within a 24 hour period could cause an
unintentional burn. In 1986, the FDA developed guidelines
suggesting a 48 hour time interval between tanning sessions.
Following these guidelines will help prevent any negative
effects of UV exposures-burning, peeling, and possibly
long-term skin damage. In general, maximum pigmentation can
be built up gradually and effectively by following a
recommended exposure schedule in 8-10 tanning sessions with
consideration to your skin type.
