My hospital recommends Deonat in their literature. I bought this but didn’t like the crystal stick. My friend gave me the Moogoo and I prefer to use this. The only thing I have to be careful of is that I’ve got Mepitel film on for radiation and it extends under my armpit. I have to be careful not to get it wet from the deodorant or it peels off. Was also told not to shave under the arm on the treatment side as it could break the skin. Instead I can carefully use an electric type razor. I make sure the other armpit looks and smells good to compensate 😊
