Expert advice on sunscreen, straight from a dermatologist

Five outlets today offer expert advice on sunscreen, with dermatologists debunking myths and offering practical tips. The obvious question is: how often should you reapply sunscreen? The National Post and The Weather Channel both say: maybe not as often as you think. The National Post says that reapplication depends on factors such as water exposure and sweat.

The Weather Channel says that experts recommend reapplying every two hours, or after swimming or sweating. However, there are caveats. The National Post notes that the frequency of reapplication can vary based on individual factors such as skin type and the specific sunscreen product used. The Weather Channel says that the SPF number on sunscreen does not indicate how often it needs to be reapplied.

Boston 25 News says that higher SPF does not necessarily mean better protection. Baptist Health and UnionLeader.com both say that people often forget to apply sunscreen to overlooked areas such as the ears, neck, and feet.
