Introduction
In general, scars refer to fibrous tissue formed after skin injury. Hypertrophic scars can be treated through methods such as medication, pressure therapy, laser treatment, microneedling, and radiofrequency ablation. It is recommended to visit a qualified hospital and undergo the above procedures under the guidance of a qualified physician to ensure safety and effectiveness. Keep the treated area clean after the procedure to avoid infection.
Generally speaking, scars refer to fibrous tissue formed after skin injury. Hypertrophic scars can be treated and repaired through methods such as medication, pressure therapy, laser therapy, microneedling, and radiofrequency ablation. Detailed analysis is as follows:
1. Medication Therapy
Silicone gel-based medications, such as Contractubex ointment, can be applied topically to form a protective layer on the skin surface, maintaining moisture at the scar site, inhibiting excessive proliferation of fibroblasts, and reducing collagen synthesis, thereby alleviating scar hypertrophy.
2. Pressure Therapy
By wearing professional elastic sleeves or compression bandages continuously on the hypertrophic scar, pressure is applied to narrow the blood vessels within the scar, reducing blood supply and subsequently inhibiting scar growth.
3. Laser Therapy
Laser therapy precisely targets blood vessels within the hypertrophic scar, destroying abnormal vessels, reducing nutrient supply, and promoting scar atrophy. The general reference price for laser therapy is 1000-3000 yuan per session. Noticeable improvement is usually observed within 1-2 months, although side effects such as hyperpigmentation and pain may occur.
4. Microneedling
Microneedling involves creating microscopic wounds on the skin surface to stimulate the skin's self-healing ability and promote collagen production, thereby improving the appearance of scars. The general reference price for microneedling is 2000-3000 yuan per session. Noticeable improvement is usually observed within 2-3 months, although side effects such as redness and pricking sensations may occur.
5. Radiofrequency Ablation
Radiofrequency ablation delivers radiofrequency energy through the skin to target the deeper layers of the hypertrophic scar, causing thermal contraction and reorganization of collagen fibers, while stimulating new collagen formation, thus improving scar hardness and appearance. The general reference price for radiofrequency ablation is 2000-6000 yuan per session. Noticeable improvement is usually observed within 1-3 months, although side effects such as swelling and numbness may occur.
It is recommended to visit a reputable hospital and undergo the above procedures under the guidance of a qualified physician to ensure safety and effectiveness. Keep the treated area clean post-procedure to avoid infection.
