I'm a 59 yr old female that has a history of basal cell carcinoma with it mainly on my scalp. I've had one Mohs surgery and 5 other BCC removed. The dermatologist prescribed the solution for me to apply twice daily and for me to shampoo, apply the solution in the morning and repeat at night leaving the solution in day and night. I started the treatment on Sunday and now it's Thursday and I've only noticed maybe 3 or 4 red spots. If anyone has used the solution can you tell me how long it takes before I should see any real reddenness etc? I'm applying it to most of my scalp except part of the back. Thanks for any info someone can share with me.
