This may be improved with a touch-up of Botox. I recommend following up with your injector. Botox results resolve in 3-4 months. Hope this helps.

It is challenging to adequately assess your issues without a personal examination.  Likely your forehead treatment is causing unwanted muscle recruitment.  This is likely caused by the pattern of forehead treatment you received.  This can be improved by superimposing a correcting treatment along the eyebrow using the Microdroplet Lift® technique.

Muscle knots can be caused by several different factors such as overusing or injuring your muscles, it can also be caused by dehydration, unhealthy eating habits, stress and anxiety. Volume and contouring of the face and temples can be created with well-placed fillers (Voluma, Radiesse, Bellafill) and Sculptra. Implants or fat are alternatives. I recommend getting a formal evaluation with a facial sculpting expert to go over your desired results and recommendations. Best, Dr. Emer

Very common  question. Those bumps are in fact bony protrusions of your skull. They are called superciliar arch (brow ridge). Usually men have more prominent brow ridge then women, but they are normal part of human anatomy. Yours look totally normal and I would not worry about then. I am attaching image of skull anatomy for demonstration.
