Saw this article and thought it worth reporting ... in the event of higher seasonal temperatures and some much~needed :sunshine: paying these islands of ours even a brief visit over the forthcoming summer months.

I wouldn't worry about it at your age Arthur :xxparty-smiley-004: :icon_lol:

Sitting in the sun until you go red is not a good idea, but it all depends on your type of skin and colour. I tend to go brown quickly, not red.

The headline in the link is true ( " Quarter of sun-exposed skin samples had DNA mutations " ) – but the study only involved 4 people, aged 55 – 73, in " healthy " eyelid skin tissue removed at plastic surgery for age-related eyelid drooping. We don’t know how much sun exposure these people had ; how the skin was judged to be healthy, presumably by microscopic examination ; or whether this applies to other skin sites and the general population. In any case nobody would consider trying to destroy a quarter of skin cells to prevent cancer.


• The eyelids ARE exposed to sunlight in everyone. Up to a tenth of skin cancers ( mostly " non-melanoma " ) occur here, especially the lower eyelid. Early detection and treatment is essential for a good outlook. They may appear as a non-healing ulcer ; altered appearance such as a red, inflamed area ; or scar-like area.


• Applying sunscreen to this site is complicated by irritation when it’s inadvertently rubbed into the eyes, so UV damage continues. Good quality sunglasses and protective clothing help, in addition to seeking shade when possible.


• I’ve reviewed the topic of sun exposure more than once in recent years - see:-
