Background and Objectives: Cryogen spray cooling
(CSC) is used to pre-cool the epidermis during dermatolo-
gical laser procedures such as treatment of port wine stain
(PWS) birthmarks, hair removal, and non-ablative photo-
rejuvenation. Thus far, heat transfer studies related to
CSC optimization have assumed a flat surface but clinical
observation suggests that human skin indents due to the
force of an impinging cryogen spray.
Study Design/Materials and Methods: High-speed
