Scars vs. scars are scars that replace normal skin structure with connective tissue after skin damage, generally not exceeding the original lesion area, with a short course, and in later stages can become softer and more stable on their own, causing no significant impact on the body’s functional form. Scars that have expanded beyond the original skin area to infiltrate the surrounding normal skin tissue have a long duration and persistent growth, appearing as irregular hypertrophic redundancies, high above the skin surface, with itchy, stinging, red or dark red growth. They are very prone to recurrence after surgical excision and increase in size compared to the original scar. Scarring is also known as crab foot swelling or giant scarring in Chinese medicine, and is a type of fibroma. It is a product of excessive proliferation of fibrous connective tissue. Scarring is very likely to form if the epidermis of a scarred person is damaged, such as trauma, surgery, mosquito bites, vaccination, burns, folliculitis, acne, etc. Scars do not fade on their own and require interventional treatment. Scars caused by various surgical procedures are locally overgrown and in severe cases have visible outward extension of capillaries. They are high above normal skin, red or dark red in color, itchy, with a tingling sensation, and symptoms aggravated by consuming spicy, alcoholic and other stimulating foods. Prevention of scars Scars and overgrowth of scars are an important complication of trauma and trauma. Its preventive measures mainly lie in the immature stage before and between scar formation, and the main purpose is to remove as much as possible all kinds of factors that cause scar proliferation, reduce the growth of scars, prevent various deformities and dysfunctions caused by scars to the body, pay attention to minimize mechanical, chemical and thermal stimulation to the affected area when serious, and avoid the occurrence of repeated pulling, frictional ulceration and infection. Current treatments for scars Although scars are more common, their cause is still unknown, which makes treatment very difficult. It has become a challenge for today’s medical community to inhibit the proliferation of fibroblasts and to prevent their recurrence and continued growth. Currently, the following methods of treatment are available: surgical excision, abrasion, laser, radiation, local seal, freezing, etc. Single treatment often fails to achieve satisfactory results and tends to worsen the affected area.
