How to treat hypertrophic scars

Keloid formation, also known as hypertrophic scarring or simply keloids, results from excessive repair during the wound healing process of the skin. In such cases, the scar tissue becomes thicker and harder than normal skin, sometimes accompanied by itching or pain. Below are some methods for managing keloid formation: 1. Topical medications: Such as silicone gel, onion extract, and asiaticoside. These medications can promote fibroblast proliferation and collagen synthesis, helping to improve keloid formation. When using these products, follow the instructions provided or your doctor's advice, and continue application for a period of time to observe the effects. 2. Adhesive patch medications: Primarily silicone gel sheets, which are semi-transparent, soft, and self-adhesive silicone patches. They can be applied externally to the scar area to help prevent scar formation. 3. Local injection therapy: This mainly involves the use of corticosteroid medications, such as dexamethasone sodium phosphate injection or triamcinolone acetonide injection. These medications can soften and fade scar tissue, achieving the desired therapeutic effect. However, it should be noted that multiple injections might be required, and the effectiveness may vary from person to person. 4. Pressure therapy: For patients with severe keloid formation, pressure therapy may be an option. Applying a certain amount of pressure using gauze or elastic bandages can accelerate the softening and maturation of scars. However, this method requires long-term adherence and should be conducted under a doctor's supervision. 5. Laser therapy: Laser treatment uses intense pulsed light generated by a laser to penetrate the skin surface and reach the dermis, stimulating collagen regeneration to effectively reduce keloid formation.
