Messages about sun safety may be getting through to younger expatriate health insurance policy holders.
Dr Elizabeth Rapley, a spokesperson for the Institute of Cancer Research, said more recent generations are taking more care of their skin.
However, older people still need to be educated about the dangers, as well as the importance of consulting their doctor about any skin-related problems.
Her comments come after figures from Cancer Research UK showed that the mortality rate among over 65s diagnosed with malignant melanoma has almost tripled in the last 30 years.
Dr Rapley pointed out that this form of skin cancer, which is the most dangerous type, is largely preventable by reducing exposure to the sun.
"Additionally, melanoma is easily treated when diagnosed in the early stages but advanced disease is almost always fatal," she added.
While younger people are taking note, older generations, who have already suffered skin damage, are less informed, she claimed.
