A prospective study analyzing the use of free public sunscreen dispensers.

Abstract

Setting: This study evaluates the impact of sunscreen dispensers in increasing sunscreen usage and awareness in Summerside, Prince Edward Island, Canada.

Intervention: In June 2022, three touchless sunscreen dispensers offering free Health Canada-approved SPF 30 sunscreen were installed in areas of high pedestrian traffic. A team of four city workers gathered observational data over a 17-day span between July and August 2022.

Outcomes: Seven days of monitoring took place at the city ballpark, seven at a children's park, and three at the city beachfront boardwalk. In total, 1202 individuals were observed near the dispensers, of whom 209 utilized the dispensers, yielding a usage rate of 17.4 per 100 persons. The usage rate varied by location, with the children's park recording a higher average (40.0 users per 100 persons), and was also weather-dependent, with increased usage on sunny days (average of 52.2 users per 100 persons). The majority of users were classified with a Fitzpatrick skin type of I or II. The sunscreen bags, designed for 2000 applications, did not require refilling during the observation period. The QR code associated with the dispensers was scanned 14 times.

Implications: The findings of this study indicate that installing sunscreen dispensers in public spaces may increase the frequency of sunscreen application. Both the location of the dispensers and the perception of weather conditions seem to impact usage rates.
