Introduction

1. Pharmacological treatment: If hypertrophic scarring has been present for an extended period, patients may receive intralesional injections of corticosteroids (e.g., triamcinolone) and/or bleomycin. 2. Surgical excision: Removal of the irregular lesion and surrounding tissue leaves a smaller, more refined wound, thereby improving cosmetic appearance. 3. Use of silicone scar sheets: These help soften scars and reduce post-inflammatory hyperpigmentation.

Scars are relatively common types of wound marks. In most cases, the appearance of a scar indicates that the wound is healing. However, for individuals with certain unique constitutional traits—particularly those with a “keloid-prone” or “hypertrophic-scar-prone” constitution—scar hypertrophy (excessive scar tissue growth) is also a very common phenomenon. Hypertrophic scarring requires effective intervention and treatment. Below, we address the question: How can hypertrophic scars be treated?

How to Treat Hypertrophic Scars

1. Pharmacological Therapy

Topical application of onion extract preparations may help reduce scar hypertrophy. During the early phase of wound healing, silicone-based products may be used prophylactically to prevent hypertrophic scarring. For long-standing hypertrophic scars, intralesional injections of corticosteroids (e.g., triamcinolone) or bleomycin may be administered.

2. Surgical Excision

Surgical excision is recommended for patients with severe hypertrophic scarring, particularly when the scar has been present for over 12 months. During surgery, the irregular, raised scar tissue is removed, leaving behind a finer, more cosmetically acceptable incision.

3. Silicone Scar Sheets

Silicone scar sheets are medical-grade adhesive dressings made from breathable, moisture-retentive silicone gel. They alleviate dryness and discomfort at the scar site, enhance skin hydration, inhibit capillary proliferation, soften scar tissue, and reduce post-inflammatory hyperpigmentation.

4. Pressure Therapy

Under medical supervision, applying consistent pressure to the hypertrophic scar area can accelerate collagen breakdown, promote healing of damaged skin, and reduce scar elevation.

5. Medical Aesthetics Procedures

Medical aesthetic interventions—including laser therapy and cryotherapy—can effectively remove hypertrophic scar tissue. Post-procedural side effects such as transient erythema or heightened skin sensitivity may occur; therefore, strict sun protection and maintenance of wound dryness are essential.

The above outlines common approaches to treating hypertrophic scars. We hope this information proves helpful to you.

What Fruits Should Be Eaten After a Miscarriage (Small Confinement Period)?

The “small confinement” period after miscarriage refers to the time during which a woman’s body recovers following a miscarriage. Generally, during this period, patients may consume moderate amounts of fruits such as apples, cherries, grapes, papayas, and blueberries. Additionally, mild fruits like strawberries and longans may be consumed in small quantities. In daily life, it is also advisable to avoid cold or cooling fruits (e.g., refrigerated or chilled fruits) and instead consume fruits at room temperature.
