BACKGROUNDWorldwide, the brow is the most common facial site to receive aesthetic treatment. However, the forehead above the brows has been comparatively less well studied with respect to both neuromodulators and fillers. Age-related remodeling of the forehead with loss of facial bone has been demonstrated on detailed radiographic studies. Concurrent loss of facial fat deposits also adds to the volume depletion. The resulting shallow scalloped depressions in the central 2/3 of the forehead give a tired and aged appearance as do the deep etched horizontal forehead lines which are often associated. Temporal hollowing may be an important associated feature.METHODSCombination treatment of the upper face with neuromodulators to elevate the brows and diluted hyaluronic acid (HA) fillers to smooth the medial glabellar complex and reflate the forehead and temple has recently become a desired and popular treatment. Several techniques have been described in the literature. All these techniques are designed to allow forehead reflation with reduction of the possibility of vascular compromise.CONCLUSIONAvoidance of the supratrochlear and supraorbital vasculature with cosmetic filler injections is possible by insertion of needle or cannula into the subgaleal space above their transition from preperiosteal to subcutaneous level. Using this technique we have so far not seen any vascular compromise and we present this technique in the interest of patient safety.
