Hello~We have a dermatology forum here, they may be able to help you more, I have put in a request for this post to be transferred to there.
In the meantime, try using Vaseline on the area and also aloe vera gel. At night, before bed, put on a good moisturizer and then put gloves on to keep it from getting on the linen and to let it soak in. The next morning, remove the glove, wash the hands and then put on the Vaseline or aloe vera gel.
