Re: allergy to eyeshadow
You can use a little cortizone cream on the lids as well if the benedryl isn't working. Usually the offending problem is with shades of pink or purple because of the dye associated with those colors. if that's the case, then try some other color. The best brand I found is Prescriptives but they are closing that line down at the end of January. I, too, have problems with Clinique so am not sure what I am going to do!
If you don't use a base under the eyeshadow, you could try that and see if it helps. It does for some people.
