- the first enzyme selected is hyaluronidase.
- This enzyme increases the permeability of the skin and connective tissue. Already naturally present in the skin, this enzyme catalyzes the hydrolysis of the glycosidic bond of hyaluronic acid. It makes it possible to depolymerize hyaluronic acid, therefore reducing its crosslinking and thus the volume of the skin surface concerned. Hyaluronic acid will then be more easily broken down and eliminated by natural means, through the connective tissue. This enzyme has the direct consequence of reducing the volume bound to hyaluronic acid.
- the second enzyme is lipase, already naturally present in the skin, it targets lipids and thus will make the surface of the skin (stratum corneum) which is essentially made up of fatty substances more permeable. It will thus facilitate the action of hyaluronidase.
- the third enzyme is protease, already naturally present in the skin, it has an action on proteins and will also improve the permeability of tissues such as the skin. It will thus facilitate the action of hyaluronidase.
- essential oils have amphiphilic properties which give them the ability to facilitate the permeability of the skin and thus to promote the action of the active ingredients of a formula.
- essential oils chosen have additional properties which complement the field of action of the enzyme complex:
- - myrrh essential oil soothing (calms sensations of discomfort in the skin), skin repairer, purifying;
- Biopsies were taken by a dissecting anatomist. The samples were then sent to a pathology office where the samples were fixed, cut and stained so that the results could be observed under a microscope.
- a superficial injection of 1 ml of hyaluronic acid (Stylage M) was performed in the right malar area with a 27G 13mm needle. This same injection is also carried out in the left malar zone in order to have an equivalence in terms of the product injected and the zone treated. Then, a pipette (approximately 0.54g) of formulation according to the example is applied only to the injected left malar zone in order to be able to observe its effectiveness compared to the right malar zone of reference.
- VECTRA H2 device with high precision optical properties allows high resolution 3D images (color resolution: 18% Mega pixels, geometric resolution: 0.95 mm) in order to visualize the topography of the skin, in particular its relief.
- 3D images are taken before and after. Once the images are available, the difference in volume between two images can be measured by visualizing the degree of contour change using a color relief map.
