The organism of an average woman using makeup and cosmetics actively absorbs about 5 pounds of various chemicals a year, Massachusetts University researchers claim. Some of the compounds present in makeup might even have side effects, starting with skin irritation to cancer.

Dangerous Chemicals in Cosmetic

There are two classes of dangerous cosmetic chemicals. The first ones are parabens, which traces have been found in breast tumor samples. Another chemicals are sodium lauryl sulfate, which can cause skin irritation.

Why Expired Makeup is Dangerous

The researchers have also found, that nine out of ten women also use expired lipstick and mascara. This can be a perfect ground for harmful bacteria. The chemicals start to degenerate, the oils become rancid and the emulsions start to separate making makeup potentially harmful. And as lots of women use about 20 different beauty products a day, the effect of these multiply combinations are very difficult to predict. So, if you wear makeup on a daily basis, you body could be absorbing up to 5 lbs of different chemicals per year, too. Please, be careful when choosing makeup and with every cosmetic product, that has been on your shelf for more than two years. Never use out-of date cosmetic products.
