Method and device for providing a composition containing hyaluronic acid
The invention relates to methods and to a device for providing a composition containing hyaluronic acid, in particular for cosmetic or medical purposes. This disclosure teaches that hyaluronic acid can be stored in a dose-metering device and that potable water from a potable water network can be mixed with hyaluronic acid using the dose-metering device such that a composition containing hyaluronic acid is formed.
1. A method for providing a composition containing hyaluronic acid, comprising the following steps:
providing a metering device containing hyaluronic acid;
taking potable water from a potable water network under pressure;
introducing the potable water by a pressure connection into the metering device;
admixing the potable water with hyaluronic acid in the metering device and thereby forming the composition, wherein the hyaluronic acid is metered into the potable water in a concentration in the range from 2 to 2000 mg/l; and
discharging the composition via a showerhead of a shower for use on the skin.
2. The method as claimed in claim 1 , wherein the potable water passes through the metering device with uptake of hyaluronic acid.
3. The method as claimed in claim 1 , wherein low molecular weight hyaluronic acid with a molecular weight of less than 400 000 Daltons or high molecular weight hyaluronic acid with a molecular weight of greater than 1 000 000 Daltons is metered into the potable water.
4. The method as claimed in claim 1 , wherein the hyaluronic acid is admixed with a preservative.
5. The method as claimed in claim 4 , wherein the preservative is sorbic acid.
6. The method as claimed in claim 1 , further comprising installing in the metering device an interchangeable cartridge having the hyaluronic acid.
7. The method as claimed in claim 6 , further comprising replacing the interchangeable cartridge with a new interchangeable cartridge.
