I posted here earlier in January about issues with sunscreen allergy, and got some useful advise, thanks SBzers

I had a massive reaction on the day before Kitestock (see the picture of my arm), which left me feeling like crap for the next 2 weeks, and got a dermatology referal which I have finally got to today!

It looks like I may actually be allergic to the sun, not the sunscreen at all, a condition called polymorphic light eruption dermatitis....
I need to wait for my next breakout to be biopsied and then look at what to do next, but what a poo for enjoying sun and sea based sports




BTW, my GP as a stop-gap recommended using Ego Sunsense Senstive suncreen (purple label, made with titanium dioxide), as one of the most non-reactive sunscreens out there, which worked fine (if a bit claggy) and so if you are a bit reactive I would now reccomend this one. For interest, it seems most suncreen allergies are usually to the additives and preservatives, not the active ingredients.
