Besides periorbital complications, other aesthetic side effects affiliated with botulinum toxin injection for forehead horizontal traces would be Buy Here the exaggeration of wrinkles, brow ptosis, “Mephisto indicator”, and periorbital edema. Paralysis of the frontalis is limited to the upper part of the frontalis and compensatory hyperactivation on the lower Portion of the frontalis muscle is achievable within the lateral Component of the forehead. Therefore, especially in men and women frequently using the frontalis muscle mass to raise their eyebrows or eyelids, exaggeration of previously unidentifiable wrinkles can occur within the border amongst the paralyzed frontalis muscle mass and non-paralyzed frontalis muscle mass. This complication will likely be self-restricting and disappears spontaneously with none further more treatment. For the compliance and satisfaction of individuals, an extra botulinum toxin injection into hyperactivated muscles could be carried out. The most important issues of treatment on the frontalis are brow ptosis and undesired eyebrow form. These issues could be corrected by using a botulinum toxin injection into muscles that antagonize the influenced muscles; even so, problems a result of the involvement of adjacent muscles are non permanent and may spontaneously solve since the botulinum toxin effects diminish.
