An in-person evaluation and examination of your dynamic facial expressions and static face is crucial. Wrinkles can be classified as dynamic (occurring with expression) or static (present at rest). If your wrinkles only form with expression, there is a good chance that Botox can nearly eliminate them. If, however, your wrinkles are static and deep (as you state in the photo), other modalities should be discussed with you for optimal results (e.g. resurfacing procedures or fillers). As long as you understand that Botox won't eliminate the static deep lines (just soften them), then you are in good shape. Having said all that, the average male dose in the glabella is around 25-30 units and around 10-12 units in the forehead. Some need more and some less. Your brows seem heavy in this photo, so a conservative approach is best initially, but again, the in-person exam is key. This stresses that only "core" injectors should perform cosmetic injectables (facial plastic surgeons, plastic surgeons, dermatologists, or occuloplastic surgeons). This is because we all have a keen understanding of facial anatomy and the effects of injecting Botox and fillers in different regions of the face. Be sure you are seeing one of us, and I wish you well!
