Men actually require a different injection strategy than women. We have thicker, stronger brow muscles. If a doctor treats a man with the same dosage as a woman, the result will be weak and you'll likely see movement still. You need a higher number of units in the glabellar complex (the elevens). Also, men want to keep some movement in the outer brows to avoid looking 'surprised.' The key is to soften the anger lines, not eliminate all expression. Regarding physical activity – it's recommended to avoid heavy lifting and bending over for 4-6 hours post-injection to prevent the product from migrating. After that, you're fine. Sweating won't ruin it, but don't rub your forehead for 24 hours.
