Influence of of Cream With the Silver Fir Wood Extract (Belinal) on Skin

Placebo Controlled Study of Influence of Cream With the Silver Fir (Abies Alba) Wood Extract on the Skin

Objective of the study is to determine the influence of the cream with Silver fir wood (Abies alba) extract (Belinal) on the skin parameters and functions in comparison to the placebo cream. 10 healthy female subjects will use the test cream on one half and placebo cream on the other half of the face and of the gluteal part twice a day for 12 weeks. Various face skin parameters will be evaluated before the cream use (the baseline), after 6 and after 12 weeks of the cream use. To evaluate the photoprotective potential of Belinal the minimal erythema dose (MED) will be determined before (the baseline) and after 12 weeks of the cream use at the gluteal area.

Detailed Description

Objective of the study is to determine the influence of the cream with Silver fir wood (Abies alba) extract (Belinal; 2% cream) on the skin parameters and functions in comparison to the placebo cream. 10 healthy female subjects will use the test cream on one half and placebo cream on the other half of the face and of the gluteal area (split-face and split-gluteal area ) twice a day for 12 weeks. Face skin parameters will be evaluated before the cream use (the baseline), after 6 and after 12 weeks of the cream use. The photoprotective potential of Belinal will be evaluated with a determination of the minimal erythema dose (MED) at the gluteal area before (the baseline) and after 12 weeks of the cream use. Comparison will be done as the mean of the individual ratios. The differences between the before-after condition will be analyzed with the statistical test of analysis of variance. In case of failure to find homogeneity in the variances the nonparametric ANOVA, the Willcoxon test, will be used. The results will be expressed as mean ± standard error for each group with a significance level of 0.05 for all the statistical tests.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Placebo Comparator: Placebo cream; Cream with 0% Silver fir wood extract (Belinal)	Other: Placebo cream; Subjects will use placebo cream twice per day for 12 weeks on one half of the face and of the gluteal area.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Improvement of photoprotective function of the skin	Minimal erythema dose (MED) of the skin will be determined. Skin on the gluteal part of the body will be exposed to 10 different doses of UVB light and 24 hours after exposure MED will be determined. Higher MED indicates better photoprotective function of the skin.	up to 12 weeks of the supplementation
Improvement of the dermis structure	Ultrasound (US) images of the dermis will be taken and intensity of the dermis determined. Higher intensity of the dermis US images indicates improvement of the collagen and elastin network.	up to 12 weeks of Belinal cream use

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Reduction of the area of the periorbital facial wrinkles	Area of selected periorbital wrinkles will be quantitatively assessed using CSI programme.	6 and 12 weeks of Belinal cream use
Reduction of the volume of the periorbital facial wrinkles	Volume of selected periorbital wrinkles will be quantitatively assessed using CSI programme.	6 and 12 weeks of Belinal cream use
Reduction of trans-epidermal water loss	Trans-epidermal water loss (TEWL) will be measured on the face using open-chamber probe. Lower TEWL indicates better skin barrier function and improved skin condition.	6 and 12 weeks of Belinal cream use
Improved skin hydration	Skin hydration will be measured on the face.	6 and 12 weeks of Belinal cream use
Improved skin elasticity	Skin elasticity will be measured on the face.	6 and 12 weeks of Belinal cream use
An increase of the dermis thickness	Dermis thickness will be measured with ultrasound imaging of the skin.	6 and 12 weeks of Belinal cream use
