What is a Botox Lift or Botox Brow Lift?

Good question! Botox should always be injected by an experienced provider.  Botox can generate a sag in the face if injected in the lower forehead region, due to it inhibiting your ability to lift the eyebrows. However, it can generate a lift as well if injected in the corners of the eyebrow, this inhibits the ability of the muscle to pull down the eyebrow. Botox can generate either a lift or a droop depending on where it is injected. Below is a video to help explain this in further detail.Wish you the best with your journey, hope this is useful!

Botox brow lift
Areas that can be injected with Botox  to achieve a brow lift 
 There are many different areas of the face that we have used Botox on in the past. Some of these are rarely used however the three main areas where we utilize Botox for the face are located around the eyes. Specifically, we utilize Botox for the area between the eyes, an area we call the glabella. This area is often referred to as The 11s. The second most common area I utilize Botox for is the lateral Eye region to alleviate the appearance of crows feet and also give a slight upward lift to the lateral brow.   Lastly the  other area we often inject Botox into is the forehead to treat the horizontal lines of the forehead.   When all three of these areas are injected at the same time and done by a well-trained injector, the end result should be a nice gentle relaxation of the muscles around the eyes that leads to a slight brow lift that is aesthetically pleasing. 

Botox works by relaxing muscles in the treated area. In some cases, these muscles may help to hold the brow up when they contract (like the muscles in the forehead that create the horizontal lines), or to bring the brow down when they contract (like the muscles between the eyebrows or around the eyes at the crow's feet area). By relaxing the muscles that bring the brow down during contraction, the brows are allowed to come up slightly, creating a lift of the brow position.
Keep in mind that these effects are usually subtle, but can make a very nice improvement in some patients. More aggressive brow lifting usually requires surgical intervention through various brow lifting techniques.
All the best,
