9 months post rhinoplasty- is benzyl peroxide 5% OK?

Hello! I am 9 months post an open rhino to reduce bulbous tip and turbinates. I have had persistent pimples and commodes on the tip of my nose which i have mostly left alone. However, I have been applying some benzyl peroxide topical ointment overnight for 2-3 days and while the size of the pimples has been reducing, the tip of my nose is very red. There is no burning or irritation of the skin, just the reddness. Is it safe to use the ointment or am i damaging my nose? Thank you!
