Johnson and Johnson has been making products for babies for over 100 years. The Campaign for Safe Cosmetics noted trace levels of certain chemicals within FDA safety margins.
Johnson and Johnson is known as a company who participates in animal testing, right or wrong, it enables them to not sell harsh chemicals to consumers.
