Have I damaged my nose by popping pimples 1 year after rhinoplasty? Please help!

It's unlikely you damaged your rhinoplasty result by picking pimples. If you actually have a suture reaction you may need a permanent suture removed by your surgeon.   If you chronically pick you may create depressed acne scars on your nose which would require treatment.   Stop picking and see your dermatologist for optimum management of your acne.  

It is important not tried popping acne or pimples on the nose as it can lead to severe infection.  Most likely has not caused any structural damage.  You should see a dermatologist on a plastic surgeon for high quality skin care to prevent these pimples and acne formation instead of trying to pop them.RegardsDr. J

It is very unlikely that you can cause damage to your nose. Sometimes if permanent sutures are used on thin skin patients, they can cause irritation and pustule formation as well.  I recommend seeing your surgeon.
