Dear rinea37,When people develop deep lines from motion that are present when their expression is at rest you may need to think past just injectables. Raising our brows is a simple expression that people do throughout the course of the day, but when those lines are really etched in there, it may be a sign of your "needing" to raise those brows a lot. You could have brow ptosis or droop, and excess upper eyelid skin. Your eyes are much happier doing their job when your forehead muscles are compensating for the heaviness and actively holding them in a higher position. Think of your eye brows as being in a tug-of-war where muscles in your forehead are pulling the them up, and your glabella muscles (between your brows) and muscles around the crows feet are pulling them down. If you make one team weak with Botox, the other gets to pull harder. If you place Botox in the glabella and crows feet, the pulling up muscles get to work unopposed and your brows raise higher. This can be good, or super creepy if over arched or unnatural. The forehead muscles will create strong creases as well. If you only put Botox in your forehead, all of that lifting power will be gone and the brows will drop even more with the pulling down muscles working unopposed. This is completely annoying for people with brow ptosis and heavy lids and you will anxiously await the day that Botox wears off. A balance of treating both areas is the best, maintaining a little lift while softening lines. If your injector goes on a mission to soften all of those transverse forehead lines, beware! If you have heavy upper lids and naturally lower set brows, a blepharoplasty and possibly a brow lift may be your best bet. Laser resurfacing can also help the deep etched in lines. It is not routine to inject forehead lines with filler, and I would not advise that. There can be some pretty scary complications. It may be worth a little trip to get a wider perspective on your best course of action if your area is geographically lacking. You know the saying "When all you have is a hammer, the whole world looks like a nail"? The good things about Botox is that is wears off in about 4 months, so if you don't love it, it too shall pass.
