Thanks for the pictures. I would keep a possibility of 'Lichenoid dermatitis' which is causing her to itch
The lesions on her upper eyelids are due to lipid accumulation at that site, Xanthelasma.
For lichenoid dermatitis i usually advice my patients to you use a potent steroid cream e.g betamethasone
valerate (betnovate) cream, mix it with an equal amount of moisturizer and apply it twice daily over that rashes for 2-4 weeks
An OTC antihistamine like cetrizine Or loratadine 10mg can be taken one or twice daily for symptomatic relief from itching.
Treatment options for Xanthelasma, which is a localised lipid accumulation, is with either CO2 Laser vaporisation OR by TCA application by your treating dermatologist
I would advice that you also get a lab test for lipid profile
done for her because Xanthelasma could be one of the signs of raised blood lipids
