Hello and thank you for your question and the pictures. Addressing the shape of your nose (especially the tip) is actually one of the most common reasons people seek out and undergo a rhinoplasty. Unfortunately, there are no good non-surgical approaches which would properly achieve what you're looking for! Fillers would not be able to fill in the area you're thinking of, and an alar base reduction will likely make your problem worse (and won't improve any tip definition). An open septorhinoplasty can best address both your aesthetic concerns and any functional issues with your nose. I would be able to adjust the size, shape, and definition of your nose (particularly the nostrils and the tip)! Rhinoplasty truly is a surgery of millimeters- and whether you're looking for a minor adjustment or a major transformation, it requires exceptional surgical skill to achieve functional and natural-looking results! Because your nose is the DEFINING feature of your face- I would only recommend seeing a surgeon who specializes in rhinoplasty procedures, and who has significant training and experience performing these surgeries. I actually trained under one of the world leading rhinoplasty experts (who performs 1,000+ nosejobs annually). I recommend for you to setup a formal consultation with me (or another plastic surgeon who is extremely comfortable with rhinoplasty procedures) to thoroughly discuss your surgical goals, undergo a formal examination, evaluate your options, and develop a personalized plan just for you. I hope this helps! Dr. Donald Groves Aesthetic Plastic Surgeon
