ABSTRACT
Undereye circles are not just a complaint of older individuals with thinning skin; plenty of young patients seek help after hearing that they look tired, even if they’re not. HA fillers can erase those circles caused by a type of bone structure and absence of the orbital fat pad that produces the appearance of deep-set eyes. The shadowy darkness can be due to the fact that the undereye surface is concave, contributing to a canyon effect that traps light. Augmenting these recessed areas with HA fillers makes the surface convex, so that light is reflected back out ( Fig. 32.2A and B ).
