I have been using Botox to treat scowl lines (aka frown lines, angry lines) since 1991, eleven years before it received its official FDA approval for this aesthetic indication. Although we have since branched out to using Botox (as well as other wrinkle relaxers, such as Dysport and Xeomin) for many, many other aesthetic facial, neck and chest problems, treating the scowl lines remains one of its most common uses. A day does not literally go by that I personally am not using it for this purpose. So, take heart. Your problem is very common and very easily addressed. Even your relatively young age for this problem is not so unusual. I in fact needed to treat two of my daughters-in-law for this with Dysport at about this same age. Treatment takes about two minutes to perform and the results typically are seen somewhere between 24 hours to a week following the treatment. And should any residual etched-in lines remain following the above treatment, these, too, can be easily smoothed out with the use of a superficial filler, such as Belotero Balance (my choice in my Upper East Side Manhattan practice, and Teosyal Redensity II, my choice in my Israel satellite facility where a far greater number of regulatory agency approved fillers are available), which has little to no tendency to engender the unwanted bluish Tyndall Effect when injected very superficially into the skin
