We are doing this research to assess the effectiveness of an oral carotenoid supplement (taken as a capsule) in improving skin health over a 12 week period.

It is hypothesised that oral supplementation of carotenoids will improve skin health parameters and the visible signs of ageing, including wrinkles, hydration, visible pores and sebum levels compared to the placebo products.

Your involvement in this study will be required for approximately 12 weeks where you will be required to take the study product once each day.

To make the timings of study requirements as convenient as possible for you, we are recruiting on a rolling basis which means that your individual start date is flexible.

Following screening via a telehealth consult, you will be required to attend our RDC Clinic in Brisbane 3 in-clinic visits over the 12-weeks during the study. Our RDC Clinic is open Monday to Saturday from 6.30am, and we offer free undercover parking.

Please see below for further information. You can find the registration of interest form at the bottom of this page.

The active product to be used in this study is CaroRite.  CaroRite is a blend of different carotenoids, consisting of Lutein, Zeaxanthin-isomers, Lycopene, Alpha Carotene, Beta Carotene. Carotenoids, a class of pigments found naturally in many fruits and vegetables, are known for their potential benefits to skin health. Carotenoids help protect the skin from oxidative damage caused by free radicals, which can result from environmental factors like UV radiation and pollution. By neutralizing free radicals, carotenoids help prevent cellular damage and the premature aging of the skin. Regular consumption of carotenoids may help reduce the risk of sunburn and other UV-induced skin damage.

As this study is placebo-controlled, you will be randomly allocated to either the active carotenoid group, or the placebo group on a chance basis. This means you will have a 50% chance of being allocated a study product containing carotenoids. During the study period, neither you nor the study investigators will know the product you have been allocated. However, if it is necessary for your health, we can find out which product you have been allocated.

Placebos are designed to look like the real product being studied except they do not contain the active ingredient. Using a placebo helps us to be confident that any effects we measure in the active group really are due to the active ingredient and not due to the body’s own reaction to a perceived treatment.
