Brief summary
The study includes the evaluation of efficacy of face serum/cream in healthy volunteers aged 25-60 years with the following methods: a) self-assessment questionnaire b) biophysical organological measurements of skin elasticity, skin microtopography, transepidermal water loss and stratum corneum hydration.
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.
Interventions
APPLICATION OF THE SERUM ON THE HALF SIDE OF THE FACE TWICE A DAY
APPLICATION OF THE CREAM ON THE HALF SIDE OF THE FACE TWICE A DAY
THIS IS THE INTERMEDIATE PHASE BETWEEN PHASE A AND PHASE B, WHERE ALL VOLUTEERS APPLY THE PLACEBO CREAM ON BOTH SIDES OF THE FACE.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| ELASTICITY | Measurements were performed on Day 1 prior to serum application, and repeated after 4 weeks. Subsequent assessment was conducted 4 weeks (placebo cream application) later, followed by a final evaluation after an additional 4 weeks of cream usage. | Skin elasticity was measured using the Cutometer 575 (Courage + Khazaka Electronic GmbH, Cologne, Germany). |
| HYDRATION | Measurements were performed on Day 1 prior to serum application, and repeated after 4 weeks. Subsequent assessment was conducted 4 weeks (placebo cream application) later, followed by a final evaluation after an additional 4 weeks of cream usage. | Stratun Corneum hydration was measured using the Corneometer ® CM 825 (Courage + Khazaka Electronic GmbH, Cologne, Germany). |
| SKIN MICROTOPOGRAPHY | Measurements were performed on Day 1 prior to serum application, and repeated after 4 weeks. Subsequent assessment was conducted 4 weeks (placebo cream application) later, followed by a final evaluation after an additional 4 weeks of cream usage. | The Skin Visioscan VC 98 (Courage + Khazaka Electronic GmbH, Cologne, Germany) was used to visualize the skin microtopography using a UVA camera. |
| TRANSEPIDERMAL WATER LOSS | Measurements were performed on Day 1 prior to serum application, and repeated after 4 weeks. Subsequent assessment was conducted 4 weeks (placebo cream application) later, followed by a final evaluation after an additional 4 weeks of cream usage. | Transepidermal water loss was measured using the MPA 5 TEWAMETER (Courage + Khazaka Electronic GmbH, Cologne, Germany). |
