I do use Metrogel for Roseacea and when out of town for a wedding and had to share a bathroom with 9 people, rushed and forgot
and put
Metrogel on the area under my nose (never done that before)
and might have gotten some on my lip in that area. That's been 2 weeks, tho. I was in the sun 3 of those days .....
I tried a search and came up with basal cell carcinoma and saw several places that said the lip is a VERY DANGEROUS spot to have BCC. That terrified me.
