AB Moisturization  research  was  spearheaded  in  the  1950s  when  Blank  demonstrated  that  low  moisture  content  of  the  skin  is  a  prime  factor  in  dry  skin  conditions.1  In  the  last  50  years,  many  scientists  have  devoted  their  lives  to  researching  moisturization  and  have  begun  to  unravel  the  mysteries  of  skin  hydration  (see  Chapter  11).  It  is  now  known  that  the  symptoms  of  dry  skin  can  be  treated  by  increasing  the  hydration  state  of  the  stratum  corneum  (SC)  with  occlusive  or  humectant  ingredients  and  by  smoothing  the  rough  surface  with  an  emollient.  Moisturizers  represent  a  multibillion  dollar  market  in  the  US.  Commonly  used  moisturizers  are  oil-in-water  emulsions,  such  as  creams  and  lotions,  and  water-in-oil  emulsions  such  as  hand  creams.  There  are  two  main  types  of  ingredients:  occlusives  and  humectants.  A  good  moisturizer  usually  contains  both  components.  This  chapter  will  identify  and  discuss  the  mechanisms  of  action  of  the  main  components  found  in  popular  moisturizers.
