| Résumé : |
The peptide hormone beta-endorphin and the steroid hormone
dehydroepiandrosterone (DHEA) play important roles in the skin. The fast that they are aise synthesised locally in the skin makes them interesting targets for cosmetic ingredients. An extract of monk's pepper (Vitex agnus-castus) was found to perform like beta-endorphin and to stimulate the synthesis of DHEA. In a clinical study, the extract showed significant effects on skin elasticity and density. |

- Fig. 1. Competition between beta-endorphin and an extract of Vtex agnus-castus in binding to opioid receptors. The smaller the indicated IC50-values (µg/ml) the stronger the brinding of the extract to the receptor
- Fig. 2. The biosynthesis of the sex hormones from the cholesterol precursor
- Fig. 3. Stimulation of the synthesis of DHEA and androstenedione by the monk's pepper extract at 0,1 %
- Fig. 4. Improvement of skin elasticity after four weeks of treatment witha cream containing 2% monk's pepper ingredient
- Fig. 5. Ultrasonographic images of the forearm of a volunteer before and after tratment. Colour scale : white - yellow - red - green - blue - black ; light colours indicating high echogenicity and thus high skin density |
