Just one quick correction here. There is absolutely nothing wrong with, nor nothing to fear from parabens. Parabens are one of the most effective preservatives ever to be used in cosmetics (and in some foods). Parabens are found in nature, many plant species produce their own form of parabens to ward off attack from microbes.
The (incorrect) fear that has been generated about parabens has come from the interenet. A published study from England by a doctor who claimed that parabens were directly tied to cancer in some patients got the whole rumor started. Recently, that same doctor has come out and said that the study was flawed, and that no direct evidence at all points to parabens being related to ANY cause of a disease or skin and health problems of any type.
Parabens are safe, and have been used for more than 40 years as one of the most effective preservative systems. Keep in mind, if parabens are not used as the preservative in cosmetics, then what is? If no preservative is used, then you are setting yourself up for potential microbial contamination (and believe me, that is a problem!). If another preservative is used, then what is it and is it effective....and safe? See what I mean.
Don't fear parabens. The internet rumor about parabens needs to die.
Hope this helps,
John
