actinic keratosis
"I used efudix for 20 days. Got all the bearable symptoms of rash, redness and sore skin. It took about 2 months for the redness to go completely.

The main long lasting side effect I have is that it's been six months and I still have permanently very greasy, greasy skin on my nose and cheeks where I applied it. 
TIP, make sure you are not prone to rosacea before using it. I didn't know I was prone but the efudix triggered the adult rosacea I never knew I had. (rosacea is like acne, it comes and goes but only in the place where I used the efudix, it's embarrassing and I don't like going in public during flare ups.)

I wouldn't recommend this treatment at all. It might be ok on small 2cm spot treatments on the body, NOT THE FACE. Beware"
