Thanks for your question and photos. You would absolutely be a good candidate for Non Surgical Rhinoplasty. Tip refinement is not the easiest thing to do with fillers, but, if the doctor is very experienced in Non Surgical Rhinoplasty, it can be done really well. I see cases just like yours frequently, probably 600 or so over the past 13 years of daily Non Surgical Rhinoplasty procedures. I have been able to achieve good definition and sharpening of the nasal tip, while maintaining a completely natural appearance. No one should be able to tell that you have had something done. Hope that helps!
For a non-surgical intervention, fillers can be used to sculpt the nose, but the tip shape cannot be improved without a surgical intervention. Please see an expert for an in person evaluation. Best, Dr. Emer
