EMERGING SCIENCE NOTE/SMART COSMETICS
CURWOOD: Just ahead: the hi-tech hunt for signs of brain damage from
tiny amounts of lead. First, this Note on Emerging Science from Jennifer
Chu.
[MUSIC: EMERGING SCIENCE THEME]
CHU: If smog alerts are getting in the way of your beauty regimen, a French
cosmetics company has an answer. L’Oreal has teamed up with the
European Space Agency to design pollution-smart skin-care products. The
idea is to cut down on pollution’s effects on hair and skin. The company
plans to create a line of moisturizers, face creams, and shampoos that are
tailor-made for the world’s most polluted cities.
To do that, L’Oreal’s scientists and beauty experts are studying daily maps
of the ESA’s orbiting satellite. Its measurements of the earth’s air, land and
sea are normally used to track rainforest destruction and melting ice caps.
Now cosmetic scientists will use that satellite’s data on ozone, carbon
monoxide, and ultraviolet radiation to study pollution in cities like London
and Los Angeles.
So far, L’Oreal scientists have observed that volunteers living in highly
polluted areas of Mexico City have exhibited increased oxidation of the
sebum – or oily skin. The company hopes to someday design a line of
cosmetics that will adapt to the changing levels of pollution from day to day.
And that’s this week’s Note on Emerging Science. I’m Jennifer Chu.
CURWOOD: And you're listening to Living on Earth.

Questions:
1. Some say that products for protecting the facial skin are for
women, not for men. What do you think as a man or a woman?
2. Do you use skin moisturizers in Taiwan? How about shampoo?
What kind of shampoo you select for your hair? Do you believe in
good and bad shampoo may give your hair different quality?
3. In Taiwan, many ladies are using an umbrella to block the
sunlight when going outdoors? What do you think of this practice
as a woman or as a man? Do you know that in North America,
using umbrellas to block sunlight is not usually seen? Can you
guess a reason?
4. Do you know of the French Company L’Oreal? If yes, how did
you get to know it? If no, how would you recommend a way for
you to remember it, say one month later?
5. How is the ultraviolet radiation related to air pollution?
Reference:
You laugh, you frown... your skin contracts
and wrinkles deepen. Don't be afraid to
express yourself!
Instead: De-Crease.
