Skin wounds often leave scars after healing. If you immediately rub the scar with fresh ginger slices for 2-3 minutes three times a day, and rub it with fresh ginger for two or three times in a row, the fleshy tooth tissue will stop growing, the wound will not leave scars, and the skin surface will be as smooth as ever. 1, How to make the wound leave no scar First of all, you should go to the hospital in time and ask the doctor to clean, disinfect, sew or bandage the wound. People often worry that cleaning the wound will delay time, shed more blood or wash the wound bigger, or even refuse to clean it just because they are afraid of pain. In fact, carefully cleaning the wound is the most basic step to avoid leaving scars and promote wound healing. For example, after trauma, the skin is embedded with impurities such as dust and coal ash. If it is not cleaned, colored particles will remain in the skin, forming ugly dust stains. Disinfection is to prevent infection, which is also the key to avoid local scars, because infection will cause the destruction of dermis and epidermis can not regenerate, so granulation tissue hyperplasia has to fill the defect and will inevitably leave scars. In addition, rinse with plenty of clean cold water immediately after scald to reduce the damage of high temperature to deep tissue; Don't disinfect facial wounds with iodine, otherwise it will cause pigmentation. After the wound scabs, wait patiently for the wound to fall off on its own. I can't help but forcibly remove the scabbed skin early. At this time, the epidermal cells being repaired have not grown completely, and without the protection of hard scab, it is easy to form scars and pigmentation. Occasionally, the newly grown epidermal cells will be taken away carelessly, which will also stimulate local inflammatory reaction and hinder wound healing. In addition, the wound will feel itchy when it heals. Scratching, scalding with hot water, rubbing clothes and other methods will stimulate local capillary dilation and granulation tissue proliferation to form scars. In terms of diet, irritating foods such as wine, pepper, mutton, raw garlic, ginger, mustard and coffee will also promote scar growth. If you eat drugs containing lead and gong, it will promote pigmentation; Sun protection cannot be ignored. Especially in midsummer, the sun is hot and full, and the new skin is immature, which is difficult to resist the radiation of ultraviolet rays from the sun and is easy to form pigmentation; Cosmetics, soap, etc. Should not touch the wound. Because all kinds of cosmetics inevitably contain heavy metals and photosensitive substances such as lead, gong and silver, it will stimulate the increase of skin pigment.
