Unfortunately, we can't give you specific advice , as this lies with your hospital treatment nurse/radiographer team. There are skin care protocols in place, and these can vary a little NHS Trust to Trust.
Skin Moisturizer that is unperfumed, PH balanced and hypoallergenic can be used for dryness and mild redness. And without SLS ( sodium lauryl sulphate) if possible. However, if the skin breaks, blisters, or becomes moist, then cream should not be used on the area, and particular dressings are provided. Do let your treatment team know that you need this reviewed, as there will be other skin dressings products that can be used.
