Understanding Keloids and Why They Form
Keloids are raised, thickened scars that develop due to an overproduction of collagen during the healing process. Unlike normal scars, keloids extend beyond the original wound and continue growing over time. They often appear after skin injuries like burns, cuts, surgical incisions, piercings, or even acne. While they are not harmful, keloids can cause discomfort, itching, and self-consciousness.
One of the most effective non-invasive treatments for keloids is silicone therapy, available in the form of silicone sheets and gels. These products are widely recommended by dermatologists and plastic surgeons to help flatten, soften, and reduce the appearance of keloid scars.
How Silicone Sheets and Gels Work for Keloids
Silicone sheets and gels create a protective, occlusive barrier over the scar, which helps in multiple ways:
- Hydration: Silicone locks in moisture, preventing excessive collagen buildup, which is the primary cause of keloid formation.
- Pressure Therapy: Applying silicone to a keloid creates gentle pressure, helping to break down excess collagen and flatten the scar over time.
- Temperature Regulation: Silicone maintains an optimal microenvironment that improves scar healing by reducing excessive blood flow to the scar tissue.
- Reduced Itching and Discomfort: Many keloid sufferers experience persistent itching and irritation; silicone sheets and gels help to soothe the area.
Best Practices for Using Silicone Sheets and Gels on Keloids
For maximum effectiveness, follow these steps when using silicone therapy:
Using Silicone Sheets:
- Clean the Skin: Gently wash the keloid area with mild soap and water and pat dry before application.
- Cut to Size: Trim the silicone sheet to cover the entire keloid with a slight margin around the edges.
- Apply Directly: Place the sheet over the keloid, ensuring it adheres well. Some sheets are self-adhesive, while others require medical tape.
- Wear Consistently: Silicone sheets should be worn for at least 12-24 hours per day for at least 3 to 6 months for noticeable results.
- Clean and Reuse: Wash the sheet daily with mild soap and water to maintain effectiveness.
Using Silicone Gels:
- Clean and Dry: Ensure the skin is dry and free from lotions or oils before applying.
- Apply a Thin Layer: Spread a very thin layer of silicone gel directly onto the keloid.
- Allow to Dry: Let the gel dry for about 5 minutes before covering it with clothing or applying makeup.
- Use Twice Daily: For best results, apply the gel morning and night for at least 3 to 6 months.
Contraindications and Precautions
Although silicone therapy is generally safe, there are some precautions to keep in mind:
- Do not use on open wounds – Silicone sheets and gels should only be applied to fully healed skin.
- Allergic Reactions – Some individuals may experience irritation or rash; discontinue use if irritation persists.
- Avoid Using on Infected Scars – If the keloid is red, swollen, or has discharge, seek medical attention before starting silicone treatment.
- Not a Quick Fix – Results take time, typically 3-6 months, and require consistent use.
Are Silicone Sheets and Gels Effective?
Numerous clinical studies support the effectiveness of silicone therapy in reducing keloid scars. Research has shown that silicone sheets and gels can reduce scar height, soften keloids, and improve overall appearance in 60-80% of cases when used consistently over several months.
Other Complementary Treatments
While silicone therapy is effective, it can be combined with other keloid treatments such as:
- Steroid Injections – Helps reduce inflammation and keloid thickness.
- Laser Therapy – Can lighten the color and soften the texture of the scar.
- Surgical Removal – Best for large keloids, though it has a high recurrence rate if not combined with silicone therapy.
- Radiation Therapy – Used after surgical removal to reduce recurrence rates.
Final Thoughts: Is Silicone Therapy Right for You?
Silicone sheets and gels are a proven, non-invasive, and accessible option for managing keloid scars. They are safe, easy to use, and highly effective when applied consistently. If you have a keloid and are looking for a cost-effective and non-surgical solution, silicone therapy is worth trying. However, for stubborn or painful keloids, consulting a dermatologist for additional treatment options is recommended.
By incorporating silicone therapy into your keloid care routine, you can significantly improve the appearance and texture of your scars over time.
