Abstract

The invention discloses a facial wound restoration dressing including the following components by the weight percentage: 0.05%-1% of chitosan, 0.1-0.3% of macromolecular sodium hyaluronate, 0.1-0.3% of low-molecular sodium hyaluronate, 0.1-0.3% of oligomeric sodium hyaluronate, 1-5% of a sodium hyaluronate elastomer, 2-3% of a purslane extract liquid, 2-3% of a notoginseng extract liquid, 2-5% of a chamomile extract liquid, 2-5% of an aloe extract liquid, 2-5% of an argy worwood extract liquid, 2-5% of a hamamelis mollis extract liquid, 1-5% of 1,2-pentanediol, 0.5-2.0% of SC-10 with the registered trademark of sensival, and the balance sterile water. The preparation method of the dressing comprises that the components are added in turn and mixed evenly and the pH value is adjusted to 5.5-7.5. The plaster containing the dressing is obtained by combining the dressing with a non-woven facial mask. The plaster is capable of inhibiting bacteria, diminishing inflammation, stopping bleeding, and promoting tissue healing and restoration.

Description

technical field [0001] The invention belongs to the field of medical dressings and plasters, and in particular relates to a facial wound repairing dressing, a plaster and a preparation method thereof. Background technique [0002] Fractional laser and injection beauty technology are currently the most clinically concerned skin beautification technology, which belongs to minimally invasive treatment. Laser cosmetology is that the laser evenly punches tiny holes on the skin, thereby forming three areas of thermal peeling, thermal coagulation, and thermal effect on the skin layer, which then cause a series of skin biochemical reactions, stimulate the skin to repair itself, and achieve skin firming and tenderness. Skin and freckle effect. These two treatment methods are relatively safe and recover faster than other treatment methods. They are suitable for lightening and eliminating pigmentation, surgical scars, burn scars, melasma, wrinkles, skin laxity and photoaging skin, etc...
