Advice for flushed sore cheeks

Finished chemo 5 weeks ago, zoledronic acid infusion fusion 3 weeks ago and just started my 2nd week of radiotherapy. My main issue at the moment is very flushed sore cheeks and a dry sore forehead. Just wondering if anyone else has experienced this nad what do they find helps. Tried my usual face cream, e45 and dermol but nothing helping at the moment. Thanks
