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

This study aimed to develop and evaluate a face serum and a face cream incorporating Cannabis extract, a prebiotic mixture containing Glycerin, Lactitol, Xylitol, and heat-treated Lactobacillus plantarum HEAL19, a non-viable probiotic (post-biotic) that retains structural components and functional benefits. Efficacy was evaluated through a randomized, placebo-controlled study involving sixteen healthy female volunteers aged 24-53. Each participant applied the active serum to one half of the face and a placebo one to the other, twice daily for 4 weeks (phase 1). This was followed by a 4-week period during which a placebo cream was used by all volunteers. Subsequently, each volunteer applied the active cream to one half of the face and a placebo one to the other, twice daily for 4 weeks (phase 2). Assessments included transepidermal water loss, skin microtopography, elasticity, and hydration, alongside self-assessment questionnaire.

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.

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.

Active Comparator: FACE SERUM
Face serum with active components (cannabinoids, prebiotics, post-biotics) was applied twice a day on the half side of the face for 4 weeks (phase 1). This was followed by a 4-week period during which a placebo cream was used.
Other: PHASE A (4 weeks)
APPLICATION OF THE SERUM ON THE HALF SIDE OF THE FACE TWICE A DAY
Active Comparator: FACE CREAM
Face cream with active components (cannabinoids, prebiotics, post-biotics) was applied twice a day on the half side of the face for 4 weeks (phase 2).
Other: PHASE B (4 weeks)
APPLICATION OF THE CREAM ON THE HALF SIDE OF THE FACE TWICE A DAY
Placebo Comparator: PLACEBO SERUM
Placebo serum without active components (cannabinoids, prebiotics, post-biotics) was applied twice a day on the half side of the face for 4 weeks (phase 1). This was followed by a 4-week period during which a placebo cream was used.
Other: PHASE A (4 weeks)
APPLICATION OF THE SERUM ON THE HALF SIDE OF THE FACE TWICE A DAY
Placebo Comparator: PLACEBO CREAM
Placebo cream without active components (cannabinoids, prebiotics, post-biotics) was applied for 4-week period after phase 1 to all volunteers. Then it was used during the second phase of the trial (4 weeks) on the half side of the face.
Other: PHASE B (4 weeks)
APPLICATION OF THE CREAM ON THE HALF SIDE OF THE FACE TWICE A DAY
Other: Intermediate phase
THIS IS THE INTERMEDIATE PHASE BETWEEN PHASE A AND PHASE B, WHERE ALL VOLUTEERS APPLY THE PLACEBO CREAM ON BOTH SIDES OF THE FACE.
