Tangent: I have been using Mexican sunscreen: Sold in Farmacias Similares for a just price (some private farmacias want fifteen bucks for Gucci Guck). Works good for me. I do not quite understand why private label sunscreen is so expensive down here.
Another yak: Check with your pharmacist at home about cumulative effects of your photoreactive Rx. Seems like doctors are as dumb as a stick when it comes to this. Your personal pharmacist can evaluate best. For instance AMIODARONE is bad juju with intense sun. Long-sleeve shirt time. The need seems to get camouflaged when driving. But left arm, head and neck (and ear) pay a stiff price.
