Health Desk-- 25 May, 2018: Ahead of the summer holiday season, a consumer group has warned that water-resistant sunscreen products work much less well after they have been worn in the sea.

Which? tested two products claiming to be water resistant and found the sun protection factor (SPF) dropped by up to 59% after 40 minutes in salt water.

A group representing sunscreen makers called the research alarmist.

Current UK tests allow manufacturers to claim a sunscreen is water resistant if the SPF drops by as much as 50% after two 20-minute periods of immersion.

Cancer Research UK welcomed the study, warning no sunscreen is 100% effective.
