I  have a rash on my face which is very itchy, it started around my left eye about a year ago and has spread to my eyebrows and down the sides of my face.  It gets worse before my period.  I have been to my GP and a dermatologist, have had antibiotics, and topical lotions to no avail.  Now have to have a biopsy.  I am 47, never had problems before now face is horribly marked and feels rough,
Hi, Itchi rashes on face could be due to irritant dermatitis, allergy hives, eczema,fungal infection or during menstruation etc. It can be diagnosed only by clinical examination in most of the cases but scratch tests, patch tests or microbiologic culture of skin to rule out infection or allergy etc. Treatment is entirely depended on the cause, so if your doctors are suggesting then you can go for biopsy or above-mentioned tests.
