Inevitably, skin damage occurs in daily life, and whenever this happens, people, especially women who love beauty, always take care of their wounds carefully, for fear of leaving scars and hyperpigmentation. So how to protect the wound? First, go to the hospital in time to have the wound cleaned, disinfected, stitched or bandaged by a doctor. Often people worry that cleaning the wound will delay the time, bleed more or make the wound bigger, or even refuse to clean it simply because they are afraid of pain. For example, if the skin is embedded in dust, soot and other debris after trauma, if not cleaned, colored particles remain in the skin will form unsightly dust staining. Disinfection is to prevent infection, which is also the key to avoid local scarring, because infection will cause the destruction of the subdermal layer, the epidermis can not be regenerated, and has to be filled by the proliferation of granulation tissue to fill the defect, which will inevitably leave scars. Likewise, boils and pustules should be treated scientifically by a doctor as soon as possible and never squeezed by hand to prevent the spread of inflammation to the deeper part. In addition, burns should be rinsed with plenty of clean cold water immediately afterwards to reduce the high temperature damage to deep tissues; facial wounds should not be disinfected with iodine, as this can cause pigmentation. Wait patiently for the wound to fall off on its own after scabbing. Often people dislike the black hard scabs that do not look good, or because they are curious, they cannot resist forcibly removing the scabs early on. At this time, the epidermal cells that are still repairing have not yet fully grown, and without the protection of the scab, scars and pigmentation can easily form. In some cases, the epidermal cells that have just grown out will be accidentally taken off, which will also stimulate local inflammatory reactions and prevent wound healing. In addition, when the wound is healing, itchy sensation will arise, and scratching, hot water scalding, rubbing clothes and other methods to stop itching will stimulate local capillary expansion, granulation tissue proliferation and scar formation; in terms of diet, wine, chili, mutton, raw garlic, ginger, mustard, coffee and other stimulating foods will also promote scar growth. If you eat drugs containing lead and tribute, it will promote pigmentation; sun protection is also not to be neglected. Especially in the summer, the sun is hot and abundant, and the newborn skin is tender and difficult to resist the ultraviolet radiation in the sunlight, so it is easy to form pigmentation; cosmetics, soap, etc. should not touch the wound. Because various cosmetics inevitably contain heavy metals such as lead, tung, silver and photosensitive substances, they will stimulate the skin pigmentation increase. As you can see, if you can treat the wound scientifically and carefully, you can definitely limit the scarring and pigmentation to the lightest degree.
