Frown lines between the eyebrows, often called "11's", are best addressed with Botox. Botox is the gold standard for good reason. The repetitive movement of the frown muscles causes the appearance of depressions and creasing of the skin. Botox minimizes or stops the movement that is causing the problem. Yes, it's temporary, lasting on average about 3 to 6 months. Is there something else?
Another option is adding a hyaluronic acid filler after maximal Botox effect has been achieved. When would this be done?
- If the furrows are so severe, Botox alone doesn't smooth the "hills and valleys"
- If etched-in creases are present that don't "release" with Botox alone
Only a hyaluronic acid filler should be used. It can be easily dissolved away if necessary. The risks of this procedure are rare, but because there are risks, only let a physician with significant experience inject filler in this location. I saw a patient recently who was injected by a nurse injector with a filler that can't be dissolved, and the cosmetic appearance is less than ideal, and luckily for the patient the mishaps that can occur injecting filler in this area didn't occur.
