Thank you for your question.I assume that you want the best aesthetic result available. This requires a consultation with an experienced board certified PS that has many years of Botox and facial aesthetic experience. In the consultation he / she will explain your facial anatomy, assess for your facial asymmetries and determine the correct dose and the correct treatment areas to provide you witht a personalized aesthetic outcome that will surpass any of the results that you will achieve from less experienced injectors. Do not go to an office where they can give you the dose required for an area of treatment without assessing you. These physicians use a "one dose fits all" approach and their results are far less than you deserve. Botox is not done well by most physicians. The product is the same but the results that can be achieved with Botox in the hands of a skilled injector are truly unbelievable. You deserve the best outcome. Seek out an experienced injector in your area, wait for the consultation and converse with your physician so that your goals and desired outcomes can be achieved. The discussion will likely include a skin care, optimizing facial volume and shape, Botox and long term program to maintain your youthful facial appearance and volume.All the best,Scott Barr, MD, FRCSCww.skinmedispa.ca
