Targeted neuromodulator injections relax the muscles pulling your mouth corners down, naturally lifting your resting expression into something softer and more approachable.
Downturned mouth corners, a resting expression that looks sad or stern, deepening marionette lines, and the gradual loss of a naturally upturned smile. This treatment addresses the DAO (Depressor Anguli Oris) muscle that pulls the corners of your mouth downward over time.
A small amount of neuromodulator is injected into the DAO muscles at each corner of the mouth. This relaxes the downward pull, allowing the lip elevators to work unopposed and gently lift the corners. The result is a subtle, natural-looking shift in your resting expression that patients consistently love.
The DAO injection is one of the most satisfying small treatments we do. It's quick, the results are immediately noticeable, and it changes how people perceive your expression at rest. Our Lincoln Park injectors have the precision this delicate area demands.
