What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change from baseline to the end of the study period in Visible signs of ageing

    Assessed using the A-One Smart Pro, this device provides and automatic skin analysis by scanner and multi-sensor. It uses a high-resolution camera to take photographs of the skin in normal, UV and polarized light. Wrinkles will be measured as thin and thick and rated on a scale of 1-10 in each area of the face: forehead, eyes, mouth and nose. An attached probe measures skin temperature and moisture.

    Visible signs of ageing measured include:

    • Skin elasticity
    • Hydration
    • Wrinkle depth and type
    • Sebum
    • pigmentation
    • Skin pH and temperature

    Measured: Baseline to week 12

Secondary outcomes (8)
  1. Change from baseline to the end of the study period in Transepidermal water loss (TEWL)

    Change from baseline to the end of the study period in Transepidermal water loss (TEWL). Analysed using a DermaLab Combo system with a probe for measurement.

    Measured: Baseline to week 12

  2. Change from baseline to the end of the study period in Skin collagen thickness

    Change from baseline to the end of the study period in Skin collagen thickness. Analysed using the DermaLab Combo system with a probe to measure.

    Measured: Baseline to week 12

  3. Change from baseline to the end of the study period in Skin carotenoid analysis

    Change from baseline to the end of the study period in Skin carotenoid analysis. This will be measured using a non-invasive device that measures skin carotenoid levels using reflection spectroscopy.

    Measured: Baseline to week 12

  4. Change from baseline to the end of the study period in Safety and adverse events

    Change from baseline to the end of the study period in Safety and adverse events. At each point of contact the participant will be asked about adverse events they may have experienced.

    Measured: Baseline to week 12

  5. Change from baseline to the end of the study period in Participant self-assessment of product effectiveness

    Change from baseline to the end of the study period in Participant self-assessment of product effectiveness. This Consists of questions related to overall satisfaction with the product and specific facial and skin properties

    Measured: Baseline to week 12

  6. Change from baseline to the end of the study period in Self-administered carotenoid intake questionnaire

    Change from baseline to the end of the study period in Self-administered carotenoid intake questionnaire. The questionnaire consists of 17 questions related to overall satisfaction with the product and specific facial and skin properties.

    Measured: Baseline to week 12

  7. Change from baseline to the end of the study period in 24-hour diet recall

    Change from baseline to the end of the study period in 24-hour diet recall

    Measured: Baseline to week 12

  8. Skin carotenoid analysis (Veggie Metre)

    Change from baseline to the end of the study period in Skin carotenoid analysis (Veggie Metre). Analysed using the Veggie Meter analyser. The Veggie Meter® is a non-invasive device that measures skin carotenoid levels using reflection spectroscopy. It shines a specific wavelength of light onto the skin (typically from an LED) and analyses the light that is absorbed and reflected. Carotenoids absorb certain wavelengths of light, and the device quantifies this absorption to determine carotenoid concentration in the skin.

    Measured: Baseline to week 12

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Carotenoids in people with Healthy Volunteer and Skin Condition, run by RDC Clinical Pty Ltd at 1 site in Australia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 6 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Australia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change from baseline to the end of the study period in Visible signs of ageing (time frame: Baseline to week 12). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06878001, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Mar 2026; AzTrials last refreshed its copy on 8 Nov 2026.
