actinic keratosis
"I have extensive AK on my face & chest and have had 5 Basal Cell & 1 Pre Melanoma lesions removed via surgery.
Because of the extensive AK & my history - my Derm tried Blue Light (Levulan). I only made it 8 minutes & had 2nd Degree burns.  Due to my reaction my Mohs Surgeon recommended Carac in a modified application as I am in sales.
I use the cream 7 days then am off 3-4 wks. I plan by time of year & my schedule as you can't be in the sun.  The Carac cream has been AMAZING!! I put it on before bed.  I documented my reaction and have found that about Day 6 I can see red trouble spots, Day 7/8 itching, Day 10 scabbing. Overall my AK has diminished by 80% after 4 cycles since last spring. I took summer/fall off."
