Visible UV Protection: Innovation From Beiersdorf
BEIERSDORF’S RESEARCH AND DEVELOPMENT TEAM has developed an innovative method by which the amount of UV protection on the skin is made visible and can be measured, according to a recent media alert from the company.
Through this method, the researchers were able not only to show what amount of sunscreen must be worn in order to achieve optimal protection, but also to prove that most
consumers use far too little.
Fourier Transformation Infrared (FT-IR) Imaging Spectroscopy works with infrared light.
According to Dr. Elke Grotheer from Beiersdorf's department of product analytics, “The color
scale of the pictures goes from green to yellow to red in which green represents enough and
red too little applied UVA and UVB filters. The results of our studies have made clear that
consumers only use between a quarter and a third of the required amount of sunscreen and
that an amount of two milligrams per centimeter squared has the optimal effect on the skin.
For an adult this means about seven to eight teaspoons for the whole body.”
“The FDA is working on efforts to make
sunscreen labels more clear and under-
standable for consumers,”said Sobel.“Cur-
rently, it’s not apparent as to which skin
care products contain UVA protection.
Once there is an agreement about label for-
mat, this will impact skin care products and
how consumers purchase them. As the im-
portance of UVA protection continues to be
a priority, it’s my belief that more con-
sumers will be purchasing products with
broad spectrum UVA/UVB protection, and
not just SPF (UVB protection).”
In addition, the FDA and researchers
are looking into potentially harmful skin
care ingredients, such as retinyl palmitate
(used in many skin care products for its
anti-aging properties), which may have a
link to an increase risk of skin tumors when
exposed to UV light, noted Sobel.
