Hand Eczema. And lifestyle changes?

My wife wrists have been dried up with flakes and reddish texture. We consulted a skin doctor and she told us that she has developed eczema. Before lockdown everything was fine and she never had these issues in past. Doctor gave her antibiotics course for 5 days and 15 days course for allergy tablets along with propylsalic nf ointment and suggested to use cetaphil lotion. After 7-8 days of treatment, her skin got almost 80 percent healed. Today is 21st day ,her allergy tab and antibiotics course along with propylsalic nf cream course all got over and for last 6-7 days she is using cetaphil lotion after every handwash (min.10 times a day almost as due to lockdown hand washing frequency is very high). Now her wrist skin again has those dry flakes along with red patches. We will follow-up doctor on Monday but I want to know is there any way to treat this with home remedies and lifestyle changes ?
