1, how to make the wound leave no scar?
Skin damage is inevitable in daily life. At this time, people, especially women who love beauty, always take care of their wounds for fear of leaving scars and pigmentation. So how to protect the wound?
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. Similarly, boils and pustules should be treated scientifically by doctors as soon as possible, and should not be squeezed by hands to prevent inflammation from spreading to the deep. 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. People often don't like the dark and hard scab skin, or because of curiosity, they can't help but peel it off 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 newborn skin is immature, which is difficult to resist the ultraviolet radiation in 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.
It can be seen that as long as you can treat the wound scientifically and seriously, you will be able to limit the scar and pigmentation to the lightest degree.
2. Prevention of keloid
Keloid and hypertrophic scar are important complications of trauma and trauma. There are many reasons for scar formation. Burn, trauma, trauma, acne (acne), ear piercing and vaccination can all form scar hyperplasia and keloid to varying degrees. The preventive measures mainly lie in the immature stage before and during scar formation. Its main purpose is to remove all kinds of factors that cause scar hyperplasia as much as possible, reduce scar growth, prevent all kinds of deformities and dysfunction caused by scar on the body, and pay attention to minimize mechanical, chemical and thermal stimulation to the affected area when it is serious, so as to avoid repeated pulling, friction rupture and infection. Usually pay attention to prevent trauma, burns, ear holes, eyebrow lines, etc. So as not to damage the dermis, especially the parts with poor immune function, such as chest, shoulders and back. I usually eat alkaline food such as kelp. Because these foods can improve their scar constitution if they are eaten for a long time.
3, the current treatment of keloid.
Although keloid is common, the cause is still unknown, which brings great difficulties to the treatment. How to inhibit the crazy proliferation of fibroblasts and prevent their recurrence and continuous growth has become a difficult problem in the medical field today. At present, there are the following treatment methods: surgical resection, grinding, laser, radiation, local sealing, freezing and so on. Monotherapy often fails to achieve satisfactory results and easily worsens the affected area. For example, the recurrence rate of surgical resection is high, laser sealing is often unbearable, and there are many diseases, such as irregular menstruation in women and impotence and obesity in men. Skin abrasion, laser and freezing can't prevent recurrence, which makes many patients and doctors feel very embarrassed. Many doctors even answer patients: "Keloid is more difficult to treat than cancer." In fact, this view is quite one-sided.
