At this point I don't have an allergy confirmed and will probably be getting a referral when I go to the doctors on Thursday. However for 6 weeks back at the end of October my eyes did nothing but water all day. Told had infection, two lots of treatment, no better so they took a swab - no infection. Told it was dry eye or blocked tear ducts (both at the same time which is very unusual) so bought some dry eye spray and it stopped within a couple of days.
Over Christmas it started again and we worked out it might be my eye cream so stopped using and it stopped watering. I tried another as the dermatitis on my eyelid was dry and they watered again so cross referenced the ingredients and the only common one was methylparaben.
So I've stopped using any products with it in while I wait to see the doctor. However yesterday I wore nothing on my face, no products at all apart from lip balm and had no watering. Today I used garnier miceller water and a body shop moisturiser (both without methylparaben is) and I've been watering. Washed it off an hour again and it seems to have stopped the watering.
I know no-one on here can diagnose but I wanted to see if anyone had any similar experiences. Currently the only thing to stop the watering is using nothing at all but to hell if I'm going to work with no make up on!!
