INTRODUCTION
For the majority of their history, sunscreen preparations were relegated to the
realm of overexposure, for those who spent an inordinate amount of time in
the sun, such as lifeguards, athletes, etc. Little or no consideration was given
to the average person, who can accumulate a tremendous amount of sun
damage through intermittent or incidental exposure. Sunscreens were the
product one took on vacation or to the beach. Rarely, except for those with hyper-
sensitivities, were they used on a daily or regular basis, until recently. Marketers
of skincare products have capitalized on the need for daily protection, and it is the
intent of the author to discuss the need, implications, engineering, marketing, and
positioning that goes behind this growing area of skin care.
