Sample the makeup... not the germs!
If you are trying out makeup at the cosmetics counter, be sure to only sample the product if the merchant provides a new disposable applicator. Did you know that using testers at makeup counters represent a direct way to transport other peoples germs onto your face and into your eyes? Also, be cautious of free make-over offers - ask the cosmetician/beautician if they are using display testers and disposable applicators. Testers represent an ideal breeding ground for germs and being aware will decrease the risk of contamination. Skin and eye irritations are the most common symptoms. For the same reason, you should never share your friends makeup either.
