Homeopathic remedies have to be individualized and there are at least 500 remedies that might apply to this problem.
So you need a classical homeopath to sit down with him and sort this out.
You should also not be using treatments without a diagnosis...and I would worry about dishidrotic eczema, which usually requires strong moisturizers and strong steroid treatmetn.
Fungal infection should be ruled out.
So, conventionally, he should see a dermatologist and have a sample of the problem sent to the lab.
Extra virgin olive oil is not only a moisturizer in a sense but is anti-inflammatory and might help in the mean time.
The best and safest topical cream is homeopathic calendula, applied three times a day until relief, then only as needed.
