Johnson's baby products are all synthetic. They contain petrochemical substances (paraffinum liquidum which derives from kerosene and causes a large number of skin issues), artificial colors and fragrances, as well as preservatives.

Having briefly mentioned this, how safe they can be? On healthy babies they won't have immediate side effects, but on long term they will to the point that you won't have any clue it's them to blame.

There are dozens of organic products these days. Why you have to wonder about Johnson's any longer?
