Will Botox help these static wrinkles or will I need filler too? (Photos)

If you do enough Botox on a regular basis, most patients will see a nice smoothing effect of even their static wrinkles. In my medical spa, it is very rare that fillers are used for the horizontal forehead wrinkles.

Hello, thank you for your question. You will benefit from botox, I recommend you to schedule a consultation with a certified expert to further discuss your treatment goals and the best way to achieve them. 

Botox it Is a wonderful option for improving wrinkles of the forehead/eyes and it can be very addictive because people love what they see. When given in certain spots, your surgeon can achieve a “chemical Brow lift” with Botox alone. There are also many other options such as laser and chemical peels that can further improve the skin itself. Botox works by relaxing the muscles and usually needs to be repeated every 3 to 6 months.
Surgery is another option but obviously more invasive and has scars.
I would recommend that you see a board-certified plastic surgeon in your area that is a member of both ASPS & ASAPS and performs a lot of brow lifts but also offers all the nonsurgical options such as Botox injectables and laser treatments. Go over your concerns with them and make sure you walk out of there with several options. 
I hope this helps and wish you all the best in your surgery and event. If it does, please take a moment to up vote this answer on the “respond” button on the top right.
