Not sure it's worth the cost...
This product was recommended by my radiologist, it provided very temporary relief but was better than nothing at the time.  I was very lucky to have minimal pain and skin issues, but I did use coconut oil and aquaphor every day starting before radiation. If you have pain from radiation it may be worth it for the cost. I did not use it enough to say if there were any skin benefits.
