AB The  appearance  of  the  skin  is  affected  by  both  the  outer  layer  of  the  skin,  the  epidermis,  and  the  middle  layer  of  the  skin,  the  dermis.  The  deepest  layer  is  composed  of  a  subcutaneous  fat  layer.  The  thickness  and  contour  of  the  fat  layer  can  also  affect  the  appearance  of  the  skin.  The  fat  layer  and  muscle  layer  below  it  are  too  deep  to  be  influenced  by  topical  skin  care  agents  so  they  will  not  be  discussed  in  this  book.  Instead,  the  epidermis  and  dermis  will  be  explored.  (For  a  more  in-depth  review  of  basic  skin  science,  see  Cosmetic  Dermatology:  Principles  and  Practice,  2nd  edition,  Chapters  1–8.)  The  epidermis  and  dermis  contain  many  types  of  cells.  Only  the  ones  known  to  play  an  important  role  in  skin  care  will  be  discussed  here  (Figure  5-1).
