Like toothbrushes that should be replaced every three months because frayed bristles lose their effectiveness in removing plaque, mascara also should be discarded every three months.
That's because after several weeks bacteria is probably growing in the makeup tube. Throw it out even sooner if it's discolored, begins to smell or if you recently have had an eye infection -- all of which signal contamination, according to Consumer Reports on Health.
Here are other safety tips:
-- Apply mascara only to the tips of your lashes. If you get too close to the root, you could block glands on the eyelids that help form tears, and your eyes may not get the lubrication they need.
-- Don't share mascara. The membrane around the eye can harbor bacteria that can easily latch onto the mascara brush.
-- Don't add liquids to mascara. Tap water, which some people use to thin mascara, isn't sterile and can allow potentially harmful bugs into the tube. Saliva is also full of bacteria and should not be used to moisten mascara.
-- Avoid lash-extending mascaras if you wear contacts. The microfibers can become trapped beneath your lens and scratch the cornea.
-- Never apply mascara in a moving vehicle. If the car stops suddenly, you could injure your eye with the brush.
-- Don't store mascara at above 85 degrees or leave it in your car for long periods _ the heat encourages bacterial growth.
