Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Description of intervention(s) / exposure
Aim: To validate the UV camera as a tool to measure sunscreen thickness and adequate sunscreen application.
This study involves one in-person visit to the researchers. Participants will be sent a reminder 24 hours before their visit via email.
Participant Involvement:
• Participants will complete a brief demographic survey. The baseline survey collects data on their demographics, skin type and regular sunscreen routines.
• Participants will be asked to ensure their face and arms are clean of any products. The researcher will take one image of the participants' face and an image of each arm using a UV camera to check they do not have any SPF products applied to their face or arms already. Facial wipes provided by the research team.
• The researcher will then measure out 3 x rectangles on the participants' face (forehead, left and right cheek) measuring 4cm x 2.5cm each. The researcher will then measure out 3 x rectangles measuring 4cm x 2.5cm on each arm. The researcher will apply by random assignment moisturiser with SPF 15+ or 50+ to the participants face and arms within the rectangles using gloves applied at 2mg/cm, 0.4mg/cm and 1mg/cm.
• UV images will be taken i) immediately after sunscreen application and ii) 20 minutes after sunscreen application (to ensure sunscreen is absorbed into skin in line with product instructions) of the participant’s front, left and right side of their face and an image of each arm using a UV camera indoors at the Institute of Health and Biomedical Innovation (IHBI), Kelvin Grove, Brisbane.
• The researchers will swab each of the sunscreen rectangle areas on the participants' face and arms to measure the moisturiser with SPF content thickness.

The researchers will supply and apply the sunscreen to the participants face and arms using a template.

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 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, no restrictions on skin type or ethnicity, 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.

Efficacy
Statistical methods / analysis
Image analysis software (Volocity, PerkinElmer) will be used to analyse the image data and determine the pixel darkness for each concentration measure. This will generate thresholds for sufficient coverage (2mg/cm), moderate coverage (1mg/cm) and low coverage 0.4mg/cm.
