How should scars be treated?

Generally, scars can be treated through topical medications, laser scar removal, microneedling, radiofrequency therapy, dermabrasion, and other methods. A detailed analysis is as follows:

1. Topical Medications

Under a doctor's guidance, topical medications such as asiaticoside cream, tretinoin cream, compound polymyxin B ointment, and vitamin B6 ointment can be used. These medications help eliminate or reduce scar marks, but long-term consistent application is required.

2. Laser Scar Removal

Laser scar removal works by applying lasers of different wavelengths to selectively target scar tissue with photothermal action. It stimulates collagen remodeling and regeneration at the scar site, making the scar gradually flatter and softer, with a lighter color. The typical reference price for laser scar removal is 1,000–5,000 yuan per session. Noticeable improvement is generally seen within 1–2 months, although side effects such as redness and pain may occur.

3. Microneedling

Microneedling involves using a roller covered with tiny needles to create numerous microchannels in the scarred skin. This process triggers the skin's self-repair mechanisms, stimulating the production of collagen and elastic fibers, thereby improving the texture and appearance of scars. The typical reference price for microneedling is 800–3,000 yuan per session. Noticeable improvement is generally seen within 1–3 months, although side effects such as infection or pus formation may occur.

4. Radiofrequency Therapy

Radiofrequency therapy delivers energy that penetrates the skin's surface to reach deeper layers, including scar tissue. This energy causes water molecules in the skin tissue to rotate rapidly and generate heat through friction, which stimulates collagen fiber contraction and realignment, promoting collagen production and improving scar elasticity and appearance. The typical reference price for radiofrequency therapy is 2,000–8,000 yuan per session. Noticeable improvement is generally seen within 2–3 months, although side effects such as redness and warmth may occur.

5. Dermabrasion

Dermabrasion involves using specialized instruments, such as high-speed rotary abrasion heads, to remove a layer of scarred surface tissue. By smoothing uneven scar surfaces, this procedure stimulates skin regeneration, allowing the healing process to produce a relatively smooth appearance and improving the overall look of the scar. The typical reference price for dermabrasion is 3,000–10,000 yuan per session. Noticeable improvement is generally seen within 1–2 weeks, although side effects such as bleeding or pigmentation may occur.

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-treatment, keep the treated area clean to prevent infection.
