Harvard medical school has a topical treatment (a cream) that is based on RNAi (RNA interference) which can eliminate herpes virus even one week after infection to effectively stop the transmission of herpes. Here are the six you should avoid sharing. I have seen varying opinions on how long the HSV virus can survive outside of the human body and wonder if it could be for a long time (i.e days or weeks) in the moist and room temperature environment of such a substance as lip gloss or vaseline. It’s easy to spread contagious germs and infections, including cold germs and even the oral herpes virus, when sharing anything that touches your lips. But it NEVER dawned on me that it was anything more than that! As for re-exposure, that virus on the toothbrush, lip balm, mascara, sheets, or towels won’t make you sick again. Toss liquid cosmetics, such as foundations, every year (some advise after four to six months).
Lipsticks and pencils? One to two years. Powdered products, such as eye shadow, blush and face powder can last longer – up to three or more years. But those guidelines depend on how sloppily you use the products (see below). Note however that some products, such as makeup base, darken a little naturally as you use them because of oxidation, says Doug Sheward, co-manager of Terry Binn Skincare Inc. A.D.A.M. A.
You find these in your Lisa Frank pencil pouch, but don’t let the seemingly clear liquid rolling around in those little bottles deceive you. But, as FDA studies show, a little bacteria is usually present in makeup before you buy it. And then, as soon as you open your new product, airborne bacteria rushes in. Spray on deodorant on the other hand? But as gross as that may sound, it’s usually not a health risk. The bacteria that causes eye infections can live on your lashes or lids for weeks before symptoms show, not to mention that tiny mascara tube is a dark, wet place where bacteria loves to live and grow. They ‘t move under their own power.
There is a higher risk for infection from contaminated products if you have a non-intact skin condition, such as active eczema. And, if you already have some sort of infection, such as herpes simplex on the lips, using contaminated applicators could spread it. If you think you might have contaminated your cosmetics from non-intact skin conditions or infections, you should toss them, or cut off the top layer of your lip balm, for example. If you have an eye infection, throw out the particular eye makeup you were using when you discovered the infection and stay away from eye makeup altogether for a week or two, Cable says. At some point, aging cosmetics lose their effectiveness to fight bacteria no matter how careful you are when using it. When makeup’s active ingredients and stabilizers break down because of age, makeup’s risk of carrying an infection is much greater, says Mark McCune, dermatologist and cosmetic dermatologic surgeon with Kansas City Dermatology in Overland Park, Kan. A.
Use common sense – don’t share your makeup with others (you don’t want to share their bacteria) and (yuck!) don’t spit in your makeup. Also, don’t add water to liquid cosmetics such as foundation for two reasons: The water has bacteria in it, and adding water can upset the chemical formula of the makeup. A changed consistency can lead to unpredictable results, McCune says. Also, instead of directly touching your makeup, as in sticking your fingers into the product, pour a little out into your palm or scoop a little out with a disposable spoon or use a disposable applicator or something similar. Shelley Palubicki, who works with the Smashbox cosmetic line at the Halls Plaza cosmetic counters in Kansas City, Mo., recommends washing brushes once or twice a month (synthetic brushes more often) with a gentle shampoo, then laying them flat to dry so that the bristles don’t break. Or, you can do as salons do, in between customers: Use sanitizing sprays. Stylists at Terry Binn Skincare Inc., for example, use an aptly named product called “Quick Dry Cosmetic Brush Cleanser,” which costs about $10 for 2 ounces, that lasts for months, says co-manager Sheward.
Refrigerating cosmetics is not necessary, says Irene Malbin, vice president of public affairs for the Cosmetic, Toiletry and Fragrance Association. you can get it at any drugstore or boots england and it’s cheap. Yes, makeup costs a lot and maybe you will never find that shade again. But at least toss that mascara regularly, and if you have a drawer of 10-year-old makeup, maybe it’s time for a fresh look anyway. You could always try something new, and if you don’t like it, you can toss it, too.
