[Social Habits] Laser treatment can leave scarring, how can it be possible to treat scarring? Scarring still needs medication and surgery. The more you treat the scar, the more obvious it becomes, so it is better not to treat it. Children are too young and afraid of pain, so wait until they grow up. There are a lot of “XX scar removal” organizations out there that can cure the scar, can you trust them? Expert Review] Why is laser treatment for scar reliable? There are many ways to treat scarring, such as topical medication, chemical peeling, corticosteroid injection, surgical excision, skin grinding, local pressure, radiotherapy, etc. But laser treatment has its unique advantages. However, laser treatment shines in the field of scar treatment with its unique advantages. (1) For small burn scars, laser treatment does not require hospitalization and can be performed on an outpatient basis; the operation time is short, usually from a few minutes to 10 minutes; the recovery period is short and will not affect normal work and life; the treatment wound damage is small, with no obvious bleeding or only a small amount of bleeding. (2) For large scars, conventional surgery often requires skin removal and implantation, and patients with large scars often face the situation of no skin available, and even if there is skin available, they face the possibility of re-growing scars in the area of skin removal; fractional laser treatment for large scars does not require skin removal, which reduces a lot of surgical pain, significantly shortens surgery and hospitalization time, and can quickly relieve pain and itching. (3) Clinical and scientific studies have shown that the fractional laser treatment of large scars does not require skin removal. (3) Clinical and scientific studies have shown that the efficacy of laser treatment for keloid scars is worth confirming: 500nm-600nm wavelength laser and intense pulsed light. Early and red hyperplastic scars are rich in blood vessels, and the hemoglobin in these vessels absorbs laser heat, which eventually destroys the endothelium and closes the blood vessels, resulting in the reduction of redness in appearance. At the same time, the reduction of blood supply causes local tissue hypoxia and nutrient deficiency, leading to apoptosis of scar fibroblasts and degradation of collagen fibers, which is the texture of the scar becomes softer. It also leads to a continuous reduction of collagen synthesis, and therefore, the texture of the scar is continuously improved. Ultra Pulse CO2 Fractional Laser: When applied to the scar tissue, 1. it can send out the “signal” for collagen synthesis, which will initiate a series of reactions such as tissue repair and collagen rearrangement. 2. The limited thermal damage can activate the stem cells on the dermal appendages (hair follicles, sweat glands, sebaceous glands), which starts the skin regeneration from the source; 3. This makes the wound healing from the flat healing in the past to the three-dimensional healing now. As can be seen from the figure below, the fractional laser penetrates deeper than the non-ablative laser, making the wound healing into a three-dimensional three-dimensional healing, while promoting the absorption of drugs. So the laser can improve both the pigmentation and texture of the scar tissue. There is a familiar story among laser scar treatment doctors: A famous American youthful and beautiful program host was thrown with sulfuric acid by her ex-boyfriend when her career was booming due to a “relationship dispute”, resulting in extensive burns all over her body, which not only disfigured her face, but also caused skin “contracture”. She was not only disfigured, but also had some basic movements restricted (opening her mouth, moving her neck, lifting her arms, etc.) due to skin “contracture”, and even encountered difficulties in taking care of herself. After several CO2 fractional laser treatments by her doctor, she gradually resumed her normal activities and gradually came out of the shadow to regain her self-confidence. Although the scar could not be completely removed, it gave her enough improvement to get a normal life and regain her self-confidence and revive her career. Although the current technology cannot meet your desire to restore normal skin, finding a professional doctor can definitely help you solve the problem.
