简要总结
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.
详细描述
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.

研究组 & 干预措施
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.
干预措施: PHASE A (4 weeks) (Other)
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).
干预措施: PHASE B (4 weeks) (Other)
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.
干预措施: PHASE A (4 weeks) (Other)
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.
干预措施: PHASE B (4 weeks) (Other)
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.
干预措施: Intermediate phase (Other)
结局指标
主要结局
ELASTICITY
时间窗: 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
时间窗: 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
时间窗: 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
时间窗: 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).
