My RO prescribed a moisturizer cream called Xclair that I liked a lot. It absorbed quickly into the skin and wasn't greasy. I believe Xclair is made in he UK. My RO warned me that it was expensive, not all pharmacies stock it, and insurance probably wouldn't pay for it. A local pharmacy (Elephant) did stock it and my insurance (Aetna) did pay for it.
Later, immediately after treatment, when I developed a bad radiation burn I found the grease in Aquaphor helpful.
