I have a spot on my eyelid that looks like a dry skin patch. It is slightly raised. Should I be concerned?

Steroid cream. I would try spot treatment for a week or so with otc Hydrocortisone cream. If it doesn't go away then you should definitely have it checked.
Dermatology consult. Any skin lesion that is new should be checked out by dermatologist---especially since sun-exposed. May just be dry skin , but cancer can be sneaky! better to be safe.... Hope it's all good!
Eyelid rash. Likely this is seborrheic dermatitis. I'd start with selsun blue shampoo with aloe to the area twice a day for a week. If no improvement, may need a skin biopsy.
