AB Subcutaneous  tissue,  or  the  hypodermis,  is  one  of  the  largest  tissues  in  the  human  body.  The  major  components  of  this  layer  are  adipocytes,  fibrous  tissue,  and  blood  vessels.  It  is  estimated  that  this  layer  represents  9%  to  18%  of  body  weight  in  normal-weight  men  and  14%  to  20%  in  women  of  normal  weight.1  Fat  mass  can  increase  up  to  four  fold  in  severe  obesity,  which  may  represent  60%  to  70%  of  total  body  weight.2  Although  gaining  fat  in  the  body  is  undesirable  for  many,  losing  fat  in  the  face  has  cosmetic  implications  as  well.  Adipose  tissue  gain  and  loss  and  volume  changes  contribute  to  the  aged  appearance  of  the  face  and  body.  This  chapter  will  review  the  importance  of  the  subcutaneous  tissue  and  its  various  functions.
