Methylparaben: This chemical is used to preserve food and cosmetics by acting as an anti-bacterial agent and helping extend the lifespan of products. However, researchers have suggested that methylparabens may increase the risk of breast cancer, or accelerate the growth of tumors. The chemical does this by mimicking the effects of estrogen in the human body. In addition, skin treated with creams that contain methylparaben can be damaged when exposed to the sun. Similarly, eye drops that contain methylparaben have the potential to damage the lining of the eyes and cornea.
