INTRODUCTION
What are recreational sunscreens and what sets them apart from other types of
products that attenuate UV rays? Is the term “recreational sunscreen” an oversim-
plification? After all, it includes many types of products whose performance and
benefits vary widely. Other terminology such as “beach products,” for example,
can be even more misleading as descriptors of products used under demanding
conditions and in a wide variety of situations. Often, sunscreen products that offer
the type of performance attributes and benefits of recreational sunscreens are
required as an important part of a daily photoprotection regime. This is especially
important for those who are frequently exposed to UV radiation, perhaps for long
periods because of their occupation (not recreation) outdoors.
