Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Primary end point of this study was to evaluate the moisturizing and elasticizing activity of "Nutrakos®" Amino Acid Food Supplement, both photoexposed and not photoexposed on skin areas (forearm volar and dorsal surface) by non-invasive instrumental measurements; the product will be tested for 1 month by female subjects, aged 35-70 years with skin photoaging. An additional aim of this study was to evaluate the product tolerance both by investigator and volunteers.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

35 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Nutrakos®
12 female subjects aged 35-70, have taken during a meal, for the 1 month ,2 stick packs/die of the food supplement
Dietary supplement: Nutrakos®
"Nutrakos®" Amino Acid Food Supplement supplies a specific mixture of amino acids that has been proven to induce synthesis of collagen and elastin, the main proteins of derma structure in fibroblasts and keratocytes.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change from baseline of superficial skin hydration
Time Frame: Basal visit (T0), 2 weeks (T2W), 1 month (T1M)
Skin electrical capacitance value was measured mono-laterally on the right or left forearm (volar and dorsal surface) with Corneometer CM825 (Courage - Khazaka, Köln, Germany). The measure of the skin capacitance properties is an indirect expression of its hydration level.
Basal visit (T0), 2 weeks (T2W), 1 month (T1M)
Change from baseline of deep skin hydration
Time Frame: Basal visit (T0), 2 weeks (T2W), 1 month (T1M)
Tissue dielectric constant value of superficial and deep skin layers was measured mono-laterally on the right or left forearm (volar and dorsal surface) with MoistureMeterD (Delfin Technologies, Kuopio - Finland)
Basal visit (T0), 2 weeks (T2W), 1 month (T1M)
Change from baseline of skin plastoelasticity
Time Frame: Basal visit (T0), 2 weeks (T2W), 1 month (T1M)
Superficial and deep skin plastoelasticity were measured mono-laterally on the right or left forearm (volar and dorsal surface) with the instrument Dermal Torque Meter (Dia-Stron Ltd., UK).
Basal visit (T0), 2 weeks (T2W), 1 month (T1M)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change from baseline of tolerance
Time Frame: Basal visit (T0), 2 weeks (T2W), 1 month (T1M)
The food supplement tolerance was evaluated considering: any adverse event related to the study treatment, which occurred during the study; any judgement reported by the volunteers.
Basal visit (T0), 2 weeks (T2W), 1 month (T1M)
