The trial

An expert team at the University of Manchester set out to put the safety of two JOHNSON'S® Baby cleansing products to the ultimate test by comparing their effects on healthy newborn skin, to water alone (bathing) and water and cotton wool (nappy changing). The largest randomised clinical trial on newborn cleansing (the gold standard in scientific research) ever held, involved 587 newborns and their mums.

The trial took place at mums' homes, so that the products could be tested in the location where they are actually used. Midwives gently took some simple, but key measurements:

  • The amount of water lost through baby's skin
  • The hydration of baby's skin
  • The overall health of baby's skin
