I have been using a retinoid on my nose for 2 years. It is a long time i know and i think i overued it, especially since it is such a sensitive part of the face.
Recently i have been getting a recurring blister on my nose, only happens though when i go out in the sun. its happened about 4 times in the last 2 years. It usually bursts and heals within 2 weeks.

The skin atm is red and dry because i had one 2 weeks ago and have not stopped picking at it since.

is this blister caused by a reaction? or is it contact dermamtitis?
or is it BCC? Im only 19 and dont use tanning beds, but some pictures of superficial bcc look like dry red patches...

thank you all
