I think you're an excellent candidate for a Non-Surgical Rhinoplasty treatment. You appear to have very thin skin, and firm tip-cartilage so you can see the vertical crease in between your two lower-lateral cartilages. Your thin-skin / firm cartilage combination makes you a challenging Rhinoplasty Surgery candidate. I would strongly suggest keeping surgery as a last resort.
I know you don't want anything permanent, but I have had excellent success correcting this crease using Silikon-1000. All of my experience with Non-Surgical Rhinoplasty over the last 10 years has been with Silikon-1000, and I have no personal experience with temporary fillers in the nasal tip. The injection must be at the correct depth, so the experience of your physician is critical.
You should consult a facial plastic surgeon experienced with Non-Surgical Rhinoplasty, and you should see many photos before you proceed.
I hope you find this helpful.
