Hi! I'm a 31 year old female and have that same "thing" on my left eyelid. I read in different places it's most likely eczema. After trying different moisturizers and petroleum jelly, pure aloe, etc., I stumbled upon Reventin lotion (from Pure Valley or Publishers Clearing House). It immediately soothed the itch and burn, and within weeks of daily application, the rash disappeared without a trace. Two years later (a few weeks ago, actually), I stopped applying Reventin just to see if "it" would come back, and sure enough, it did. So I'm back to using the lotion which seems to be the only thing that works, aside from Rx's, maybe. Hope this helps :)
This sounds like eczema. The skin gets dry and can crack. Their is no cure and it probably will spread. Then one day it will go away as fast as it came. The only thing you can use without a prescription is moisturizer. Find a cream or ointment that works for you. The typical treatment is hydro cortisone but don't use that on your face, it will make the skin thin. Their are a lot of different views on the subject and most doctors act like it is just something you will have to live with. I found that cutting down on sugar and increasing vegetables helps a lot. I have it on and off in the creases of my legs.
I use cetaphil cream or Aveeno. Don't wash the area as this makes it worse. try to use all natural soaps or Dove all natural. Make an appointment with a dermatologist. But it might be gone by the time you see him. Winter is always bad, you might want to get a humidifier, that can help a lot with dry winter air.
