What is a Botox Lift or Botox Brow Lift?

In physiology, we term the actions of muscles to be agonist and antagonist muscles. This refers to the results of the muscle contraction.
Certain muscles play "tug-of-war" with areas of the face. Examples include:

The corner of the mouth: Muscles lift the corner in a forced "cheeky" smile or turn the corner of the mouth downward with frowning.
The outer part of the eyebrow: The squinting muscles pull the eyebrow downwards while the forehead muscles pull it upward.
The central upper lip : "pursing" muscles pull it downward, whereas muscles just to the outside of the nostril create a "gummy" smile.

If we inject the antagonist muscles, the agonist muscle action will predominate and take over. In the examples above:

Injecting the muscles that pull down the corner of the mouth (the depressor anguili oris) will allow the muscles that lift the corner to take over and minimize downturning or frowning.
Injectting the squinting muscles relaxes the pulling down of the brow and creates a chemical "forehead/brow lift"
Injecting the muscles to the outside of the nostril allows the upper lip to relax and eliminates the gummy look when smiling.

I hope this helps!

As we age, our eyelids naturally sag and droop. A combination approach would be best to see visible improvement. In terms of non-surgical treatment options, I would recommend a Chemical Brow Lift (using Botox, Dysport, Xeomin, or Jeuveau) and filler injections to rejuvenate the temples, eyebrow, eyelid, eye troughs, upper eye hollows, and forehead. I typically combine this with Ultherapy and thread lifting to lift the brow; RF and skin tightening laser treatments to stimulate collagen production and rejuvenate the skin; and laser or superficial RF devices for improvements in texture, color, and any crepey skin around the eyes as needed. In some cases, surgery is the best solution to achieve the desired results. See an expert for a formal consultation. Best, Dr. Emer.

The brows have several different muscles pulling on them from different angles. The only elevator of the brow is the frontalis muscle that also creates the horizontal forehead lines. We prefer to treat this muscle lightly to soften those lines but also preserve some forehead motion and prevent causing the brows the drop. The orbicularis oculi is a muscle that circles around the eye. This helps with squinting and blinking to close the eye. It also pulls the brow down. By treating this muscle laterally it can prevent the muscle from pulling the brow down and allows the frontalis muscle to pull it up further. If over done it can cause lateral peaking or a 'spock brow' deformity.
