Introduction
Keloid scars may be caused by genetic factors, abnormal skin tension, impaired blood circulation, foreign body irritation, infection, or other reasons. If the above conditions occur, treatments such as fractional laser therapy, scar excision, microdermabrasion, or medication may be used under a doctor's guidance to repair the scar. It is recommended to visit a正规 medical institution and undergo these procedures under the supervision of a qualified physician.

Generally, raised scars may be caused by genetic factors, abnormal skin tension, circulatory disorders, foreign body irritation, infection, and other reasons. When the above conditions occur, treatments such as fractional laser therapy, scar excision, microdermabrasion, or medication can be used under medical guidance to repair the scar. Specific analysis is as follows:

1. Genetic Factors

Individuals who carry genetic traits predisposing them to excessive scar formation are more likely to develop raised scars. If there is a family history of similar scarring, the scars may be more prominent and harder to fade. Early intervention is recommended in daily life, along with avoiding trauma to reduce the chance of scar formation. Fractional laser treatment can also be considered under a doctor's advice. This method uses laser beams to create microscopic pores evenly across the skin, generating three zones—thermal ablation, thermal coagulation, and thermal effect—that stimulate deep dermal collagen regeneration to improve the scar. The reference cost is 2,000–8,000 yuan per session. Noticeable improvement typically appears within 8–10 days, although side effects such as redness and pain may occur.

2. Abnormal Skin Tension

During wound healing, uneven distribution of tension in surrounding skin tissues may lead to overgrowth of scar tissue, resulting in a raised surface. It is advisable to use pressure garments or bandages regularly to reduce tension and promote flattening of the scar. Scar excision surgery may also be chosen under medical supervision. For severe raised scars, surgical removal of the scar tissue followed by skin grafting or flap transplantation can restore the skin. The reference cost is generally 5,000–10,000 yuan per procedure. Improvement is usually seen after 2–3 months, but possible side effects include allergic reactions and infection.

3. Circulatory Disorders

Poor blood circulation at the wound site impairs the delivery of nutrients and removal of metabolic waste, potentially leading to raised scar formation. Improving local blood flow through appropriate massage—about one hour daily—is beneficial in daily life. Microdermabrasion performed by professionals can also be used for repair. This procedure mechanically sands down the scar surface surgically to promote regeneration of new tissue, gradually fading and smoothing the scar. The reference cost is typically 5,000–10,000 yuan per session, with visible improvement expected after 2–3 months. However, symptoms such as pain and swelling may accompany the treatment.

4. Foreign Body Irritation

Retained foreign bodies in the wound—such as dust or suture remnants—can stimulate excessive scar tissue growth, leading to raised scars, often accompanied by tenderness and irregular scar shape. Patients may, under medical advice, use medications such as Kangfuxin Liquid, injectable sodium penicillin, or dexamethasone acetate tablets for treatment.

5. Infection

Improper wound management allowing bacterial invasion and subsequent infection can trigger overgrowth of scar tissue, resulting in raised scars, possibly accompanied by redness, swelling, and pain. Patients should follow medical instructions to use medications such as erythromycin ointment, fusidic acid cream, or amoxicillin capsules for treatment.

It is recommended to visit正规 medical institutions and undergo the above procedures under the guidance of qualified physicians to ensure safety and effectiveness. Daily attention should be paid to protecting the skin, avoiding injuries, and promptly and properly treating any wounds to prevent infection and minimize the risk of scar formation.
