Botox would be an excellent option to help you with your arch in your eyebrows. Whereever the arch is more exaggerated you can place a small amount of botox like 1-5 units to to lower the arch. It could require more than one shot over each arch depending on how the arch is shaped. I would start conservative and find the right amount for you. For a more permanent solution, you can do a brow lift in a differential way to shape the eyebrows. It could entail elevating the lower portion or lowering the arched portion.
