The other thread got me thinking - is skin only getting damaged if it changes colour? I'm blonde haired, fair skinned and I used to go pink if I so much as looked at the sun. However, 6 years ago, I underwent a course of UV treatment on the NHS for bad psoriasis and I swear it's totally changed my skin! I spent all day Friday at Hyde Park and, although I'd applied sun cream at 7am, I realised once we were in there that I'd brought an empty bottle with me so couldn't reapply. So all day in the sun and I've not changed colour one bit. I saw countless people with angry looking shoulders and arms but it's literally not touched me, and it got me thinking that I can't remember the last time I tanned even a little bit.
So, is the sun still doing as much harm even though I appear to no longer tan? How is it even possible to not burn?? I only applied factor 20 once at 7am and was out til 11pm in the middle of a big field! My friend had applied the all day, factor 50 stuff, is a lot darker skinned than me and she has tan lines. I'm some kind of freak aren't I?
