Spanish peolple were always quite careful of the sun because, as anothers sun cultures, we always knew how dangerous it was. People used to protect against the sun not only because the social consideration of fair skin but also and above all because of the damaging consequences of the sun exposure: freckles, wrinkles, skin aging... Then, in the sixties and the seventies began coming people from center and northern european countries, where the summer sun is not by far as dangerous as here, and began sunbathing. The young spanish people, instead of remembering what our elders knew about the sun, began imitating the foreigners. Now you can see the effects of the sun in people of all ages, but especially in women from 30 y.o., women with darken, leathery and thick skin, that look 20 years older than they are.
