There is a bogey man and his name is parbens.
In recent years reports came out that they may cause cancer, the word to read is MAY. So suddenly many companies went into panic mode and removed them and used that as part of their advertising. No pabens. The general public then went into panic mode and saw them as the big bad.
Now the thing is parbens are used in every day in foods, meds that your doctor can prescribe you. Liz Earle has always had them in her products and saw nothing wrong with them(this was way before Avon bought her out).
You will find two schools when you google, the screaming how they will give you cancer(this of course is not proved 100%, a few poor little mice in a lab caught cancer), and others who say there is nothing wrong with them. They caused a big stir because of the poor mice and that is what people remember, mice caught cancer, no doubt because they were injected with 100% parben for days or weeks on end.
