Plain English Summary

Background and study aims
SelectSIEVE®Rainbow is a synergy of natural compounds acting together. The functional properties of its components are safe and well known: cellulite and weight management, reduction of orange peel appearance, improvement of microcirculation.
The aim of this study is to evaluate the efficacy of a food supplement in improving face skin conditions and in reducing cellulite-derived skin imperfections

Who can participate?
Female subjects aged from 35 to 65 years old showing showing fine lines/light wrinkles, dull skin and uneven skin tone and mild to moderate cellulite-derived skin imperfections

What does the study involve?
Participants are asked to attend clinic visits at screening and after 28, and 56 days of food supplement intake. During the screening visit, the principal investigator informs the participants about the trial procedure, risks, and benefits. Only participants giving their informed consent are enrolled in the study. The trial staff and the subjects then fix the date for the first visit. During the first visit, the subjects will answer all the questions on the medical questionnaires given by the principal investigator. The participants are then randomly allocated to take the active food supplement or the placebo products for 56 days.
According to a previously defined randomization list subjects will be divided into two study groups:
- 30 subjects take the active food supplement
- 30 subjects take the placebo food supplement
All the measurements/assessments are carried out using non-invasive procedures. The total duration of each visit is 30 minutes. The study duration is 56 days with one intermediate check at 28 days.

What are the possible benefits and risks of participating?
The potential benefits are related to an improvement of face skin parameters (skin profilometry – wrinkledness and eyebags volume), skin moisturization, skin brightness, skin evenness, skin pinkish, eyebags and dark circles appearance and of cellulite derived skin imperfections (skin smoothness, body circumferences, skin microcirculation, “orange peel” skin appearance). The potential risks are assumed to be mild to moderate and are not expected to pose a risk to health. Risks associated with the procedures involved in this study are judged as minor. All precautions will be taken to ensure that the risk is the lowest possible. All the measurements carried out are minimally invasive and no side effects are expected from the measurement process.

Study hypothesisThe study aims to assess the efficacy of a food supplement in improving facial skin conditions and in reducing cellulite-derived skin imperfections on a panel of 60 subjects after 28 and 56 days of intake. The aim of this study is to evaluate its efficacy in improving facial skin conditions and in reducing cellulite-derived skin imperfections. In particular, evaluation of face skin profilometry – wrinkledness and eyebags volume, skin moisturization, skin brightness, skin evenness, skin pinkish, eye bags and dark circles appearance, skin homogeneity and cellulite derived skin imperfections (skin smoothness, body circumferences, skin microcirculation, “orange peel” skin appearance) are evaluated
Ethics approval(s)Approved 01/12/2022, Comitato etico indipendente per le indagini cliniche non farmacologiche (Via XX Settembre 30/4 - 16121 Genova, Italy; +39 (0)10 5454842; ssinf@messaggipec.it), ref: 2022/09
ConditionFine lines/light wrinkles, dull skin and uneven skin tone and mild to moderate cellulite-derived skin imperfections
InterventionThe active food supplement intervention (SelectSIEVE®Rainbow) is a synergy of natural compounds acting together in order to reduce both cellulite and body weight (ROELMI HPC, Via Celeste Milani, 24/26, 21040 Origgio (VA), Italy); while the placebo food supplement intervention is maltodextrin and magnesium stearate. Both the active and the placebo products are used as follows: one capsule per day intake with a glass of still water for 56 days.

Test subjects are randomized into two groups of 30 subjects as follows: one group takes the active food supplement and one group takes the placebo food supplement.
In order to standardize the volunteer’s cosmetic habits, a base face and body cream without any cosmetic activity is provided to the subjects to be used during the whole study period instead of the usual face and body care routine.

A restricted randomization list is created using PASS 2008 (PASS, LLC. Kaysville, UT, USA) statistical software running on Windows Server 2008 R2 Standard SP1 64-bit Edition (Microsoft, USA) by a biostatistician and stored in a safe place. The randomization sequence was stratified using “Efron’s biased coin” algorithm with a 1:1 allocation ratio. The allocation sequence was concealed from the in-site study director in sequentially numbered, opaque and sealed envelopes, reporting the unblinded treatment allocation (based on the subject entry number in the study). The A4 sheet reporting the unblinded treatment was folded to render the envelope impermeable to intense light. A masked allocation sequence was prepared for the staff delivering the intervention based on the subject entry number in the study.
