Parabens are a group of chemical preservatives often added to increase shelf life in personal care products. You can identify parabens when reading a product's ingredient list by looking for ingredients such as methylparaben, butylparaben, or any other ingredient that contains "paraben" in its name.
Inexpensive and easy to come by, parabens are used very commonly in many products you use everyday. However, due to increased customer concern over health concerns associated with parabens, some companies are choosing to replace parabens with alternative ingredients.
Why should parabens be avoided? The basis behind the concern over paraben use comes from a 2004 study that identified parabens in breast cancer tumors. Follow up studies have shown parabens to act as weak estrogen mimickers. As with other chemicals that can disrupt the endocrine system, parabens may be contributing factors to increased breast cancer risk.
Although much of the evidence about potential concerns with parabens is only suggestive, it is known that parabens are readily absorbed into the bloodstream. Since these chemicals easily enter the body, why take the risk that they may be causing your body damage? Find and use paraben free products instead.
