I had a tiny BCC removed from my forehead about 6 weeks ago after having absolutely no reaction to Aldera. Even though the lesion was tiny, my dermatologist took out a big chunk of skin...leaving a nasty 2" scar. Now, she has me treating other bumps on my forehead and upper back with Carac. I was scared to start with the Carac after reading these notes. However, I used it for 14 days with absolutely NO REACTION. Does this mean that it's not working?? No itching, soreness, not even slightly pinking up. Maybe my body just doesn't react to these meds.
