I spend plenty of time outside, no worries here.
Funnily enough I happen to be doing a PhD developing a treatment for skin cancer and the first big no-no is sun beds.
Most sun creams/lotions will protect against UVB induced damage to a degree, for a short period, but not UVA, which penetrates much further into the skin (and thus causes more damage to this upper layers of the skin). Just because UVA reaches further down that UVB doesn't mean that UVA isn't causing damage to the upper layers. Basal cell and squamous cell carcinomas are far more common in sunnier areas with Caucasian populations and those that have high levels of radon, such as South West England.
There are developments into new compounds to add to sun creams and hopefully I'll be collaborating with one of the leading researchers in the field, in September!
