Introduction
Generally speaking, there is no single most effective method for removing hypertrophic raised scars. Hypertrophic raised scars can be treated through topical medications, laser scar removal, cryotherapy (freezing), microdermabrasion, or surgical excision. After treatment, it is important to keep the affected area clean and dry, avoid scratching or rubbing, protect from sun exposure, apply prescribed scar repair medications as directed, and avoid spicy or irritating foods.
Generally speaking, there is no single most effective method for removing hypertrophic raised scars. Hypertrophic raised scars can be treated through localized medication, laser scar removal, cryotherapy, microdermabrasion, surgical excision, and other methods. If discomfort occurs, timely medical consultation is recommended. Detailed explanations are as follows:
1. Local Medication Therapy
Topical corticosteroid-containing ointments or gels, such as asiaticoside cream, triamcinolone acetonide cream, and betamethasone cream, can help reduce scar inflammation and hyperplasia. However, these medications should be used under medical supervision to avoid worsening the condition.
2. Laser Scar Removal
Laser scar removal utilizes photothermal energy to precisely target hypertrophic scar tissue. The water within the scar tissue absorbs the laser energy, vaporizing instantly and disrupting the fibrous structure of the scar. This process also stimulates collagen remodeling and regeneration, gradually flattening the scar and bringing its color closer to that of normal skin. The typical reference price for laser scar removal is 500–2000 yuan per session. Improvement is usually noticeable 1–3 months post-procedure, although side effects such as redness, pain, and swelling may occur.
3. Cryotherapy
Cryotherapy involves applying extremely cold substances, such as liquid nitrogen, to rapidly freeze hypertrophic scar tissue. This causes intracellular ice crystal formation, damaging cellular structures and functions, leading to scar tissue necrosis and shedding. The typical reference price for cryotherapy is 200–800 yuan per session. Improvement is usually noticeable 3–6 months post-treatment, with possible side effects including redness and blistering.
4. Microdermabrasion
Microdermabrasion employs high-speed jets of fine crystal particles that strike the surface of the hypertrophic scar, removing the upper layers of scar tissue while stimulating skin regeneration. Following microdermabrasion, the skin initiates a repair mechanism, promoting collagen and elastic fiber proliferation, resulting in smoother, flatter skin and improved scar appearance. The typical reference price for microdermabrasion is 500–2000 yuan per session. Improvement is generally noticeable 2–3 months post-treatment, with possible side effects including redness, pain, and warmth.
5. Hypertrophic Scar Excision
Hypertrophic scar excision involves surgically removing the scar tissue directly. Depending on the size, location, and tension of the scar, the wound can be repaired through direct suturing, skin flap transfer, or skin grafting to achieve scar removal. The typical reference price for hypertrophic scar excision is 2000–8000 yuan per session. Noticeable improvement is usually seen 3–6 months post-surgery, with possible complications such as infection and bleeding.
It is recommended to visit a reputable hospital and undergo these procedures under the guidance of a qualified physician to ensure safety and effectiveness. Post-operative care includes keeping the treated area clean and dry, avoiding scratching or friction, protecting against sun exposure, applying prescribed healing ointments, and avoiding spicy or irritating foods.
