Botox Brow Lift Vs Thermage for the Eyes?

As I have written in answering a related question, Botox injection just below the eyebrow can create a lifting of the brow by relaxing the muscles that normally pull or hold the brow down.  This so-called "chemical browlift" is most commonly used to lift the outer third of the brow but can be used along its entire length.  From an aesthetic perspective, the brow arch should peak between the middle and outer thirds.  This Botox effect will only last 4-5 months, whereas a surgical browlift should last many years.  Thermage works by tightening skin due to application of high energy waves.  Generally speaking, Thermage has been used more frequently in other areas of the body, not around the eyes or for browlifting, and I don't think the subtle skin tightening would withstand the normal downward muscular pull in that area.  My preference would be for either the Botox treatment or surgery, depending on your degree of brow sagging.

Thermage is not generally very effective for lifting the brows. Botox works as a "chemical brow lift" to improve the brow position slightly. This must be injected in such a way as to not lower the brows, which is easy to do with Botox. For this reason, an expert physician injector is recommended.All the best,

Wow--Botox and Thermage are totally different treatments.
Botox works by turning off the muscles that pull down the brow and cause wrinkles between the brows. By turning off the downward pull of the muscles, the brow elevator muscles work un-opposed and pull the brow up. The produces a "chemical" browlift.
Thermage lifts the brows more superficially by tightening the skin. This "shrinkage" allows the brow to elevate some.
