AB SUMMARY  POINTSWhat’s  Important?The  water  content  of  the  SC  should  be  greater  than  10%.The  formation  of  fine  wrinkles  is  associated  with  low  water  content  in  the  skin.Increasing  water  consumption  will  increase  the  water  content  of  skin,  especially  in  those  who  consume  less  than  2,500  mL/day  of  water.The  microbiome  affects  skin  hydration  and  skin  hydration  affects  the  microbiome.Relative  humidity  below  30%  can  lead  to  dry  skin  unless  the  patient  has  high  levels  of  sebum  production.  The  optimal  relative  humidity  for  skin  hydration  is  60%.Increased  humidity  increases  skin  elasticity.An  elevated  pH  impairs  barrier  homeostasis  and  SC  cohesion,  decreasing  skin  protection  from  the  environment.What’s  New?Cell  phone-attached  devices  to  measure  skin  hydration  are  inaccurate  due  to  humidity  and  ambient  air  flow.Use  of  moisturizers  in  newborns  decreases  the  development  of  atopic  dermatitis,  food  allergies,  and  asthma.What’s  Coming?The  effects  of  cannabinoids  on  the  skin  barrier  and  skin  hydration  are  unclear.
