With the new green movement in trying to promote a more sustainable lifestyle and natural products that are being promoted lately, we've seen a lot of controversy and claims that many things are now "paraben free". But what exactly are parabens? And why should we be so afraid of them? It's effective anti-microbial properties are effective and used in everyday things from shampoos to makeup products which is used as a preservative in nearly 90% of all cosmetics. Parabens, which include butylparaben, isobutylparaben, ethylparaben, methylparaben, propylparaben, isopropylparaben, and benzylparaben, can be absorbed through the skin and migrate into the bloodstream and body tissues. Due to the migration of the parabens, concerns have been raised recently, about possible links between some cosmetic products containing parabens and the incidence of breast cancer.
