Is reduction of supra alar crease possible? (photo)

It is not very frequent request but I do not see any reason why deep allar crease can not be corrected; you will have to accept the scar as a replacement, however. Good luck.

Hi,The alar crease can be softened by repositioning or supporting the lower lateral cartilages with grafts. It is unnatural for it to be completely eliminated but in cases where it is very deep, it can certainly be softened.Best,

Dear samleee,
Thank you for your question. It is difficult to make an accurate assessment and recommendations based on photographs alone. I recommend you seek an in-person consultation with a facial plastic surgeon or plastic surgeon that specializes in rhinoplasty who can perform a thorough examination and recommend the best surgical approach to meet your goals. Depending on the thickness of your skin and orientation and shape of your lower lateral cartilages, there are possible maneuvers to help minimize the supra alar crease if your surgeon agrees it is feasible and will improve the overall appearance of your nose. 

Everybody has a crease or groove above their alar. Its entirely normal anatomy.
Whilst softening it by placing grafts deeper maybe possible it is not necessarily desireable. Id be careful what you wish for.
In sone patients sebaceous thickening of the skin can contribute to accentuating the crease. It is not possible to make that diagnosis from photographs
