Study summary

Multicentric and double-blind randomised comparative clinical study in Argentina and Brazil. Under dermatological and ophthalmological control 4 visits: inclusion [Day(D)0], D28, D56, D84 Ethical committee required.

Read the detailed description

Primary objective:

To evaluate the efficacy of two cosmetic products (SCARCr tester 1 and SCARCr tester 2) in association to the topical medical treatment (Ivermectin or Metronidazole) in supporting the improvement of persistent redness due to rosacea and in soothing discomfort sensations, under dermatological and ophthalmological control.

Secondary objectives:

To evaluate the cutaneous and ocular tolerance of two cosmetic products in subjects presenting with rosacea under treatment with topical Ivermectin or Metronidazole for 56 days, and 28 days after applying the cosmetic products alone. To evaluate the efficacyof two cosmetic products through clinical evaluation of the symptoms related to rosacea after 56 days of concomitant use of the cosmetic product with the topical medical treatment, and 28 days after applying the cosmetic products alone. To evaluate the efficacyof two cosmetic products through instrumental measurements of redness after 56 days of concomitant use of the cosmetic product with the topical medical treatment, and 28 days after applying the cosmetic products alone. To evaluate the evolution of the quality of life of the subjects over the period of use of the association of the topical medical treatment with the cosmetic products (56 days) and 28 days after applying the cosmetic products alone. To evaluate the immediate and long-lasting eCicacy and cosmetic qualities of the cosmetic products based on self-assessment questionnaires by the subjects. To compare the two products tolerance and efficacy.

Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from May 2024 to primary completion in Jan 2025, 7 months.

Of 42 interventional studies with no phase under Rosacea, half reached primary completion within 13 months of starting (the median), counting those still running; a quarter within 7 and three quarters within 29. This study's 7 months is below that.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 28, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
