Silicone-based gels, such as Silnoscar Gel or Dermatix Ultra Gel, are often used to soften and flatten small keloids (thick, raised scars caused by excess healing tissue after an injury). Apply a thin layer to clean, dry skin over the scar once or twice daily, as advised by your doctor. You may need to use the gel consistently for several weeks or months to see improvement. Do not use it on broken or irritated skin. If the keloid increases in size or becomes painful, please consult a dermatologist for further treatment.
