I was told pure lanolin oil works so I used it. My plastic surgeon is very pleased with my skin condition even after 30 rads! I have virtually no scars after a skin/nipple saving mastectomy. I am continuing to use the lanolin oil every other day as we do the expansion in preparation for DEIP flap surgery. It is very, very thick so mix in a drop or two of water and it spreads on nicely. Certainly has worked for me
