Hi, I was fortunate to only need 5 days of radiation on half my R breast and under arm back in September. I have sensitive skin and didn't want to be plagued with itching, burning and discomfort so gladly invested in the StrataX. I was told I only needed a small pea size for that area and shown how to feather it on with my finger tips. It should just feel a bit sticky, not moist. You don't spread it generously and rub it in like Moo Goo. I expected to get some symptoms, but I had none at all in the 6 weeks following treatment while continuing with StrataX. So it was well worth it for me. After the 6 weeks I stopped using StrataX and still had some left! I have since been applying Moo GOO liberally on the scar area around my nipple and under my arm massaging it in very well twice a day. That is working well. There's still some hardening but it's reducing.
