I had my eyebrows threaded several years ago for the first time. Since then, I have had redness above and through both eyebrows. I have seen a dermatologist, who tried hydrocortisone cream, a course of Elidel, and a patch test for allergies. None of these treatments have been successful and no allergies flagged up. This problem is affecting my well being as I am very self conscious about the redness. I don t have any spots or broken skin.I use only perfume free products, and I don t know what else to do. Can you recommend anything else?
