Around month 8 or 9 I noticed a weird mark on my nose. It looks bad after the shower or after being outside, but other times it's not super noticeable. My doctor recommended lazer treatment but it either hasn't done anything, but I've only done 1 so far. What are my options? What could this be? The picture attached it when it looks particularly bad after I went on a hike (but wore plenty of sunscreen)
