What is hypertrophic scarring?

In general, laser scar removal works on the principle of selective photothermolysis. Specific wavelengths of laser light are preferentially absorbed by pigments, hemoglobin, and other components within the scar tissue, generating a thermal effect. This process breaks down pigment particles, stimulates skin cell regeneration, seals abnormal blood vessels, and promotes collagen remodeling, thereby improving the appearance and texture of scars to achieve a corrective effect.

A scarred uterus refers to a uterus with scars. There is no established minimum thickness of the scarred uterus that defines danger. Generally, a myometrial thickness less than 2 mm in the lower uterine segment is considered risky. Pregnant women with a scarred uterus require enhanced monitoring in the late stages of pregnancy. If the myometrial thickness is found to be less than 2 mm or is accompanied by scar abnormalities, early hospitalization for evaluation is recommended, and pregnancy may need to be terminated promptly when necessary, to reduce the risk of uterine rupture and ensure maternal and fetal safety.

In general, skin grafting refers to a skin transplantation procedure, and scars refer to fibrous tissue repair after wound healing. The general reference price for skin grafting is 5,000-10,000 yuan per session, and noticeable improvement is usually observed within 10-14 days. Pain and infection may occur after surgery. During scar recovery following skin grafting, vitamin E can be used as an adjunctive treatment, although its effectiveness is not well established, and caution is advised in its use.

In general, scar flap transplantation refers to flap transplantation surgery. Flap transplantation is usually effective, especially suitable for repairing large-area scars, deep tissue defects, or scars accompanied by functional impairments. However, strict indications must be followed, and treatment plans should be developed by experienced physicians after evaluation. Postoperative anti-scar therapy and functional rehabilitation exercises are also necessary to maximize the repair outcome.

After removing stitches from finger wounds, scar repair can be achieved through methods such as using anti-scar medications, applying sun protection, gently massaging the scar, avoiding irritation to the scar, and using scar sheets to aid healing. Scientific interventions can help reduce scar hypertrophy and promote scar fading. If the scar shows obvious redness, swelling, increased pain, severe itching, or abnormal growth, prompt medical attention at a dermatology clinic is recommended.

一般情况下，烧伤疤痕是否可以完全去掉，需根据疤痕的具体情况进行判断。若有不适或疤痕问题，Recommendation及时就医咨询Skin科或整形外科专家。日常需注意，疤痕恢复期间避免抓挠、摩擦，防止加重损伤或引发感染。选择Treatment方式前需经专业Doctor评估。

The red mark from a first-degree burn usually fades within a few days to 1–2 weeks, with the exact duration depending on individual constitution, burn area, and care practices. As a mild form of burn, it typically does not leave scars after healing. Therefore, there's generally no need for excessive concern about the redness from a first-degree burn; with proper basic care, most cases resolve naturally in a short period. If the red mark persists beyond two weeks without fading, prompt medical evaluation is recommended.

In general, burn ointments cannot directly remove already-formed scars. However, their primary function is to promote wound healing and prevent infection, which indirectly reduces the likelihood of scar formation or lessens the severity of scars. Additionally, in cases of deep burns, even with proper use of burn ointment, scars may still develop due to extensive damage to skin tissue, requiring further targeted treatments.
