Are parabens dangerous?
The answer is an unequivocal “no”.
It is true that in laboratory trials, many different ingredients have an effect similar to hormones – including parabens – but so do soya and other food products. The effect is, however, much smaller than the effect of many other natural oestrogen (there is a corresponding study here, for example).
This does not mean that it produces a hormonal effect when using the product. Firstly, preservatives are only used in the smallest possible quantities. Secondly, products are usually only applied to the skin, and lastly, parabens are rapidly broken down if tiny amounts end up in the body.
Throughout their long history of use, ingredients like parabens have always been tested by recognised experts. Parabens are safe according to the conclusions drawn by many scientific studies.
