Embodiment 1

[0056] Example 1 : Anti-elastase effect of silver fir twig essential oil

[0057] through the la The hydrodistillation of the harvested twigs (twigs and needles) yields the essential oil of silver fir twigs of the Abies alba species. Hydrodistillation was carried out for 4 hours from 1.15 kg of dried and crushed branches under reflux distillation.

[0058] The obtained essential oils were analyzed by gas chromatography coupled to mass spectrometry. It mainly contains limonene (35%), alpha-pinene (10.8%) and camphene (12.3%) with lesser amount of bornyl acetate (4.6%).

[0059] Its elastase inhibitory activity was assessed in vitro by comparison with:

[0060] - commercial Rubus idaeus L extract (Hydraberry from VITALAB), and

[0061] - Alcoholic extract of silver fir twigs obtained by extracting dried and finely chopped twigs in ethanol with stirring for 4 hours.

[0062] For this, the enzyme, substrate (Ala-Ala-Ala-p-nitroaniline) and the sample are brought into conta...

[0070] Example 2 : Beauty composition

[0071] The following compositions were prepared in a manner conventional to a person skilled in the art by mixing the following components in the indicated weight proportions.

Abstract

The invention relates to the use of an essential oil of white fir tree (Abies alba) branches as an elastase inhibitor for combating the signs of skin ageing, in particular for limiting and / or reducing the degradation of elastic skin fibers, the loosening of skin and / or the loss of elasticity of the skin and / or the appearance of wrinkles.

Description

[0001] Invention subject [0002] The present invention relates to the use of silver fir (Abies alba) essential oil as an elastase inhibitor for combating the signs of skin aging, in particular for limiting and / or reducing the degradation of skin elastic fibers, skin laxity and / or loss of skin elasticity and / or or the appearance of wrinkles. Background technique [0003] The skin consists of two interacting parts, the superficial epidermis and the deeper dermis. The natural human epidermis is mainly composed of three types of cells, namely keratinocytes, melanocytes and Langerhans cells, which constitute the vast majority. The dermis provides firm support for the epidermis. It is also a nourishing element for the epidermis. It is mainly composed of fibroblasts and an extracellular matrix consisting mainly of collagen, elastin, and a substance called ground substance, which contains sulfated (such as cartilage sulfated Glycosaminoglycans, proteoglycans, and various proteas...
