Scar removal is to improve the symptoms of local scars left by physics, medicine, laser or surgical methods, which affects the appearance and function of human skin and soft tissue, causing serious damage to skin and soft tissue, which cannot be completely repaired by itself. Once a scar is created, it will not disappear. Several common scar treatment methods: scar excision and non-invasive suture; Repair the scar after normal skin expansion with soft tissue expander; Drug injection in scar; Scar grinding; Local spraying and coating can improve appearance and reduce scar hyperplasia. But one thing is certain, all treatments can't completely eliminate scars. American scholars used scar antibody to study the immunotherapy of scar, and threatened to win the Nobel Prize, but three years later, this immunotherapy has not been applied to clinic, that is, it has not achieved the expected results. Visible scar treatment still has a long way to go. Surgical skin grafting
Cut off qualified skin from other parts of the body and transplant it to the scar-removed part. This method is the most important, which can obviously improve the severe scar after transplantation, but it may leave scars on the peeled parts of the body. Most patients' own fat or dermis is used as filling material. Generally, the cost of skin grafting surgery is charged according to three area specifications: large, medium and small.
Release and shape modification
This is after scar removal, the incision is changed to "Z" shape, which is most suitable for webbed scars. Reticular scar forms skin adhesion, which especially hinders behavior. By mobilizing the skin tissue next to the scar through surgery, the influence of the scar on the body function is minimized.
Buried dilator
Two dilators (water bags made of silica gel film) are buried under the skin on both sides of the scar, and normal saline is injected regularly to make the skin bulge here and leave room for new skin growth. After the dilator is taken out, the extra skin can make up for the skin at the original scar. The method of burying the dilator works best on the head or face, because there are bones inside to resist the dilator and make it expand outward. This is a good way to treat scars, but it takes a long time and requires hospitalization for at least one month. Because it requires two operations: embedding and taking out, using dilator and hospitalization, its cost is also high.
Biological scar removal
The extracted natural animal and plant essence is mild and non-irritating. Compared with foreign treatment methods and means such as laser, freezing and skin grafting, it has the advantages of obvious curative effect, safety, reliability, no toxic and side effects, convenience and low price. Nano-decomposition activation therapy and nano-phagocytosis repair method are adopted, and high-tech nano-transdermal technology is used for biological scar removal. The latest scar removal technology, nano-decomposition activation therapy, is applied to the skin surface, retaining the highest active components of the drug, enabling the drug to quickly penetrate the skin surface, enter the dermis, decompose the connective tissue that formed the scar before, repair the broken fibrous tissue, restore the collagen structure of the basal layer of the skin, make it orderly arranged, and maintain the smoothness, luster, elasticity and toughness of the skin. Biological scar removal adopts nano-phagocytosis repair method. The unique LEYA active factor can penetrate deep into skin surface cells, quickly activate the ability of MB cells in basal layer to phagocytize and dissolve melanin, effectively reach damaged skin Y tissue, promote blood circulation, enhance epidermal cell metabolism, discharge scar tissue pigment, effectively promote cell regeneration, prevent pigment variation of damaged skin, smooth lymphatic circulation and restore normal skin color.
Silicone patch therapy
Silica gel patch is applied externally to hypertrophic scar, which has the function of preventing and treating scar hyperplasia. After applying the self-adhesive silica gel patch on the scar surface, it can reduce the evaporation of water on the scar surface, increase the hydration of the scar tissue, and increase the permeability of the mixture of water-soluble proteins and various water-soluble inflammatory proteins on the scar surface. These water-soluble proteins can diffuse on the skin surface, reduce the water-soluble proteins and products in the matrix, reduce the fluid pressure, and make the scar mature, soften and flatten, and the color of the scar tissue becomes lighter, close to the natural skin color. Silicone patch therapy has been widely used since 1980s, and it is the only self-treatment method for scars that has been proved to be effective. The incidence of sensitization and other complications of non-invasive treatment is extremely low. [ 1] [2]
The silica gel patch used to contact the skin must be made of absolutely sterile and impurity-free medical silica gel and produced in a sterile medical product production environment. In medical silica gel tablets, the technological indexes such as density and elongation are also different. Silica gel patch with a certain thickness has better water retention performance and better effect on materials under pressure and temperature. From the point of view of self-adhesion, a good silicone patch can be used for up to four weeks, while some silicone patches will lose their adhesion within a week or two, and they can't closely fit the skin and can't play a good role in removing scars.
