Common Lower Face Concerns
Gummy Smile
A gummy smile, also known as gingival display, occurs when the upper lip lifts excessively during facial expressions, exposing the gums above the teeth. This can make individuals feel self-conscious about their smile lines or hesitant to smile. Through precise injection sites, botox injections can limit the muscle movement responsible for the excessive lift, reducing the appearance of gum tissue for a more balanced smile.
Cobbled Chin
A cobbled chin, characterised by a pebbled or uneven skin texture, is caused by overactivity in the mentalis facial muscle. This concern is particularly visible during certain facial expressions. With injectable treatments, Botox smooths the skin by temporarily relaxing the muscle beneath, resulting in a refined, even chin appearance.
Downturned Mouth Corners
Drooping mouth corners can create the impression of a sad or angry expression, even when at rest. This is often due to natural muscle movement and ageing processes. By targeting these muscles, Botox mouth injections can lift and soften the appearance of the corners, rejuvenating the area. For comprehensive results, this treatment can be paired with filler treatments, such as lip filler, to enhance lip shape and symmetry.
How Botox Mouth Injections Work
Botulinum toxin injections are a minimally invasive solution that temporarily relaxes specific facial muscles, reducing the appearance of facial wrinkles, such as smokers’ lines, marionette lines, or lipstick lines. Administered by a medical professional, these treatments target precise injection sites to ensure natural-looking results while maintaining normal facial expressions.
For a gummy smile, a small amount of product is applied to the upper lip area to limit the lift during animation, ensuring less gum exposure. For cobbled chins and downturned corners, Botox relaxes the muscles causing tension or drooping, creating a smoother and more refreshed appearance. A tailored approach is essential, as each individual’s facial lines and concerns are unique.
