Skin Rash After New Face Cream. Tried Topical Vita E, and Hydrocortisone, No Results?

I developed a rash 5 days ago after applying a new face cream. I have been applying topical vitamin E (from bodyshop) to moisturize my skin as it has become very dry as well, but i did not use any medicated cream so far. the rash is in patches of several raised spots, very reddish, and itchy. i have hydrocortisone cream but that cream makes my skin itchy on itself (i have very sensitive skin). can taking antihistamine tablets help decrease the redness? please help me doctors.Thanks so much
