1) Americans Disregarding UV Warnings
2) Improvement of Naturally Aged Skin with Vitamin A
The following two studies, although on different topics and conducted by different medical groups, go hand in hand with
regards to the importance of skin protection as well as reversing sun damage for
skin health.
1) Americans Disregarding UV Warnings
A new study, published recently in the Centers for Disease
Control and Prevention's
Morbidity Weekly Report, says an increasing number of people are not
using proper sun-protection measures. The percentage of American adults
who suffered sunburn increased from 31.8 percent to 33.7 percent during the
years between 1999 to 2004, suggesting that warnings about using proper sun
protection aren't being heeded. The study also found that significant
portions of most racial and ethnic groups reported getting sunburned in the
three years - 1999, 2003 and 2004 - during which the data was collected.
Overall, according to the study, men were more likely to get sunburned than
women.

2) Improvement of Naturally Aged Skin
with Vitamin A
A University of Michigan Medical School Study suggests that cream containing Vitamin A (Retin A) helps reduce age-induced
wrinkles and helps boost production of skin building compounds.
The study, findings of which were published in the May issue of the
Archives of Dermatology, involved 36 elderly people (average age of
87) on whom researchers applied 0.4 percent lotion to the upper-arm and control
lotion with no Vitamin A to the other arm. The lotions were applied
for 24 weeks. The researchers graded the wrinkles, roughness and overall
severity of skin aging before treatment and at two, four, eight, 16 and 24 weeks
after starting treatment. Skin biopsies were taken at the beginning and
end of the 24-week treatment period.
The study found that wrinkles, roughness and overall aging were significantly reduced where the Vitamin A lotion had been
applied, compared with the arms treated with the control lotion.
Post-treatment biopsies showed increased production of procollagen on arms that
received the Vitamin A lotion.
(If you feel the appearance of your skin is
suffering due to sun damage, start using a broad spectrum sunscreen now and
consult with Dr. S. as to whether Retin A (Vitamin A cream) is the best solution
for you.)
