Polymorphic Light Eruption. Anyone else?

Does anyone else have this?

I was diagnosed as a young child and it hasn't really got any better!

I'm 51 now and I've never met anyone else with it or even anyone who has heard of it.
The NHS website describes it essentially as a mild irritation but it's debilitating. It also suggests it lessens over the summer as your skin becomes acclimatised. Mine doesn't.

It's not as bad as when I was a child but that ls probably because I'm an adult and avoid being outside altogether if I can help it.

The GP said it's basically an allergy to UV light, which seems to be held up by the fact that, when I was younger, I'd react even in nightclubs or at attractions with UV light. We were asked to leave places when I was a child because it looked to management like I had measles.

Exposure to sun causes a severe stinging nettle type rash on any exposed parts of my skin. Raised white lumps that group together to cause blotchy patches that are intensely itchy and surrounded by redness that are also incredibly painful to touch. I get it on my face and hands still but not as severely as I used to or on less exposed parts of my body. I don't get it so much on my face now but get what I assume is angioderma - swelling on my face that's really unattractive and causes large swollen sagging eye bags essentially that extend half way down my cheeks 😭 Antihistamines can take the edge off the itching but not really the pain and not the reaction in the first place.

I cover myself in factor 70 suncream but can still have reactions in strong sun (like this weekend has been).

Unfortunately, covering up is also hard because I don't tolerate heat very well and don't regulate my body temperature well so I overheat quickly and become ill through that. Using suncream can also have the same effect. It's a pain.

I'm also quite photosensitive generally. I wear sunglasses all the time outdoors unless the sky is dark and overcast with grey clouds. Even a cloudy sky can be too bright and painful!

It's never early occurred to me to go back to the GP about it. When I was a child (late 70s/early 80s) they said there was nothing for it but to stay out of the sun - which is hard to do! Avoiding the middy sun (11am - 5pm) doesn't really help because sun outside that also cases a reaction and being at work makes it difficult too.

It just makes normal life quite hard from light spring through to summer. I have a really shady garden (intentionally) and can sit out under the trees but no one else wants to constantly chase complete shade so it makes normal socialising with others tricky too.

I just wondered if anyone else on here has this or what your symptoms are like because, like I say, I've never met anyone else with it!

Yes...just on my face and neck. Started when I was 50. Still get it in heat 18 years later. Also mixed with rosacea.

I have it too. Very bad on my chest and arms. I also have a skin reaction to very cold weather!

It’s a little less severe as I’ve aged but blights my life every year. I use massive factor suncream that blocks UVA and UVB, and a very thin prophylactic cover of steroid on any exposed skin although I generally cover up…I chase shade, even crossing roads multiple times. People think I’m nuts but I don’t care if it saves me from the pain.

Is it related to Xeroderma Pigmentosum? I once had neighbours whose two little children had this, they called them moon children. They couldn’t cope with any daylight at all. The mum pushed them around in a covered black box, poor kids.

As someone who's fairly recently developed itchy dermatitis and is struggling 💐

@TheSunHasGotHisHatOnHipHipHipHooray it is prescribed cream and it really takes the edge off. Sometimes, it itches so much, I can't sleep so it helps a lot. Sun cream can work, too, as a preventative but isn't a guarantee. Hit and miss and not sure if it's dependent on application or SPF/brand.

TheSunHasGotHisHatOnHipHipHipHooray · 27/05/2026 07:58

Wow! It's really nice just to hear from.others who have it!

I do remember the GP mentioning steroids but said they wouldn't prescribe and my mum was concerned about steroid cream so I've never really considered it.

I do take antihistamines but haven't really found them to be much use other than for the itching, which it takes the edge off.

Do you use over the counter ones or are they prescribed?

Yes, had it my whole life as does dd2 though it has lessens as I aged and I take antihistamines when I know i need to be in high uv situations for extended periods

WellFineThen · 27/05/2026 07:49

Yes. You can ask for steroids from GP. It helps with the itch and the dryness when the itchy part subsides. Have had it lifelong as does MIL.

Ive never heard of it and don't have it but just wanted to say it sounds hard and hope someone else comes along with useful experiences soon!
