@Pookie all I used was qv intensive the preferred cream of my clinic and I just slathered it on as many times a day as I could manage my appts were middle of the day so I could moisturise before I went to work after treatment and again before bed. As predicted by my onc I did have some very mild burns (I’ve had worse sunburns being stupid in my 20’s) they were mainly under boob in the crease and I had to do solugel and glad wrap dressings for a few days. The other less worse days I used a silicone dressing called Mepilex Lite on the nurses advice.
My biggest tip is to have a bra that won’t rub. That will do far more good than anything else
