How to treat hypertrophic scars from chickenpox

Hyperplastic raised scars from chickenpox can be improved through topical medications, laser therapy, intralesional scar injections, surgical excision, and physical compression therapy. The appropriate treatment should be selected based on the size of the scar and how long it has been present. If the scar continues to grow, is accompanied by pain or itching, or affects appearance, prompt medical evaluation is recommended.

1. Topical medication: In early stages, silicone gels or asiaticoside-containing ointments may be used to moisturize the skin and inhibit fibroblast activity, thereby reducing scar hyperplasia. Consistent application for 3–6 months is required, making this option suitable for small scars in their early formation stage.

2. Laser therapy: Uses the photothermal effect of lasers to destroy scar tissue and stimulate collagen remodeling, improving scar elevation and pigmentation. Multiple sessions are typically needed and this method is appropriate for moderately hyperplastic scars of moderate size.

3. Intralesional scar injection: Involves injecting corticosteroids or other medications directly into the scar to suppress excessive fibrous tissue growth and soften the scar. This is ideal for prominent, firm, hypertrophic scars and must be performed by a qualified physician.

4. Surgical excision: For large, severely hyperplastic scars or those impairing function, surgical removal followed by meticulous suturing may be performed. Postoperative anti-scar treatments are necessary to prevent recurrence.

5. Physical compression therapy: Involves wearing elastic pressure garments or applying adhesive silicone sheets to apply continuous pressure, which reduces local blood flow and inhibits scar proliferation. Suitable for scars on body parts that are easy to wrap, this method requires long-term adherence.

In daily life, avoid friction or scratching the scar. Practice sun protection to prevent pigmentation, reduce intake of spicy and irritating foods, and consume more foods rich in vitamin C and protein to promote skin healing. Early intervention during the initial phase of scar formation yields better results.
