DHA, a sugar molecule that bronzes just the top layer of the skin,
is the only coloring agent that has been approved for use by the US Food and Drug
Administration (FDA). It has been a common ingredient in cosmetics for many
years. Self-tanning products are available as lotions, creams, sprays and wipes
and typically contain 3-5% DHA. Results generally occur within a few hours, and
the color will fade in 7-10 days as you naturally shed skin cells.
There is no hard evidence that DHA is harmful or carcinogenic to
humans when applied topically and in the small, recommended doses. When
applying or administering spray tanners, be sure not to ingest or inhale the
product. Protective gear should be worn to cover the eyes, mouth and nose.
I recommend maintaining your natural complexion,
but if you prefer a darker skin tone, self-tanners are the safest route. The
scariest option is undoubtedly a visit to a tanning salon. Nearly 30 million
people use tanning beds each year in the US; of those, 2.3 million are teens.
Below are some alarming facts on indoor tanning, which can also be found at www.skincancer.org.
·
Those
who make just four visits to a tanning salon per year can increase their risk for
melanoma by 11 percent and their risk for basal cell carcinoma and squamous
cell carcinoma by 15 percent.
·
Indoor
ultraviolet (UV) tanners are 74 percent more likely to develop melanoma than
those who have never tanned indoors.
·
Frequent
tanners using new high-pressure sunlamps may receive as much as 12 times the
annual UVA dose compared to the dose they receive from sun exposure.
