Measuring coverage of low and high sun protection factor (SPF) cosmetics

This study aims to measure the difference in coverage between lotions containing SPF 15+ and SPF 50+ using a UV camera. This study involves one in-person visit to the researchers. Participants will be sent a reminder 24 hours before their visit via email. Study procedures: • Complete a brief demographics survey. The baseline survey collects data on their demographics, skin type and regular sunscreen routines. • Have their face (clean skin) photographed with a UV camera. • Participants will be randomised to apply SPF 15+ to either the left or right side of their face. Participants apply SPF 50+ to the other side of the face. • Three images will be taken of the participant’s front, left and right side of their face using a UV camera indoors at IHBI both immediately after and 20 minutes after sunscreen application. • Participants are asked about their satisfaction with the products in an in-person interview. Participants apply the sunscreen themselves, as they usually would. UV Camera - The UV camera is designed to image ultraviolet light. As a result, skin with sunscreen on it will appear darker onscreen than skin that's been missed, or that requires a reapplication. The more sunscreen that is present, the darker the skin will look. The photography session is based inside at IHBI or the individuals workplace (such as other QUT buildings) using a UVA light Lamp, it uses UV LED which is tested to be safe by the International Electrotechnical Commission. It does not emit UVB, the chief cause of skin reddening and sunburn. It is safe to use on eyes. As an extra precaution, participants will be asked to sit to have their photo taken and asked to close their eyes, then the UV light will be turned on. Participants will not look at the UV light. Study population: Persons 18 years of age or older, general population who work mostly indoors. Image Consent Participants are asked to provide separate consent for their use of images in publications and presentations. This is optional, and individuals may still participate in the study if they chose not to provide consent for use of images.
