Nose tip gets red and cold easily 1.5 years after rhinoplasty (Photo)

I am 1.5 years post op with super thin skin after a closed rhinoplasty and when its a tad colder inside or when im outside the tip of nose gets so cold and red and purple. The quality of the skin seems to be so bad, my skin also blanches where cartilage bumps are and sometimes i get a small scab in the middle. Is this something to be worried about? Thanls in advance
