Is my nose getting bigger?

It is not typical for the nose to look thicker in two months without an event such as trauma or infection, and the pictures are too far away to really tell. My best advise would be that if you are not happy with the appearance of your nose, simply go for a consultation with a rhinoplasty specialist. After a good examination, he/she could tell you if there is a problem and what can be done to make you happier with the straight on view.

Unfortunately the pictures you posted are not clear and zoomed in to comment on whether your nose is getting bigger. Without trauma or sinus infection it is uncommon that your nose should getter bigger after 18 years of age.

The skin onthe nose can thicken with time. Your photos have you so far back I really can't comment in your particular case. If you have a condition called Rhinophyma, this can be thinned out.
