In terms of your smile, certainly procedures, such as botox, can be done to limit a gummy smile. Also, though, performing a rhinoplasty with alteration of the tip can improve the appearance of your nose and smile by altering some of the muscle (depressor) around the mouth. Hope this helps.
If your main concern is that your tip dives down when you smile then you might be a good candidate for a cutting the muscle, or release of the depressor muscle. You would need a proper exam to evaluate the need to do this, including smiling to see how the septum and tip respond. There are a few reasons for a gummy smile, and some treatments involve more complex maxillary surgeries. But if you main concern is reshaping the nose and the tip diving down, a basic rhinoplasty should accomplish this.
You are an excellent candidate for Rhinoplasty surgery. You are a very pretty lady with a male nose that needs a feminine nose. The depressor muscle can be addressed at the same setting to address the "gummy" smile. Best wishes!
Thank you for the question and the photos and clearly you would benefit from a rhinoplasty. So go on some consults with experts in your area that will take your photo digitally and then alter it to show you what can be accomplished with surgery.
