DAO Botox treatment targets the depressor anguli oris (DAO) muscle, which pulls down the corners of the mouth, often causing a permanently downturned or "sad" expression. Before the procedure, individuals may have downturned mouth corners, marionette lines, or fine lines creating a tired or unhappy look. After DAO Botox injections, which involve small, precise injections into the DAO muscle, the corners of the mouth are lifted mildly to a neutral or slightly upturned position, softening the expression and reducing frown lines. The results typically begin to appear within a few days to two weeks and last around 3 to 4 months. There is minimal downtime, and side effects like mild swelling or bruising usually resolve quickly. Before treatment, consultation helps plan the appropriate dosage based on facial anatomy and aesthetic goals. The procedure is quick, often described as a slight pinch, with optional numbing cream. After treatment, patients can resume daily activities immediately but should avoid touching the area and sleep on their back for a few days. Photos taken before and after can show a visible improvement in the "sad smile" and marionette lines, giving a more youthful, approachable, and fresh appearance. DAO Botox is a non-surgical, natural-looking option to subtly lift the mouth corners and improve facial expression. In summary, DAO Botox smooths and lifts the mouth corners, reduces lines, and corrects a downturned mouth expression, with visible before and after results that rejuvenate the lower face with no significant downtime.
