No need to worry. I have been injecting Botox for aesthetic reasons since 1991, and the kinds of wrinkles over your eyebrows that you show in the photo occasionally occur when an injector, usually an inexperienced, novice injector, does not place the Botox in a balanced way and inadvertently gives the competitive edge to the opposing muscles. Fortunately, this is easy to treat. A microdroplet or two of additional Botox on each side placed in the appropriate locations will help to soften the wrinkles that disturb you. Having said that, you should also know that, in order to prevent a sagging brow, Botox is not injected in the 3/4 inch to one inch region immediately above the brows, meaning that any etched wrinkles in that region are best addressed with fillers. Going forward, make sure you consult with a board certified aesthetic physician and ask to see his/her before and after photos. Best of luck, and not to worry.
