Silicone for keloid scars: what to know

A keloid is raised scar tissue that extends beyond the original wound and may feel firm, itchy, tender, or tight. Silicone creates a flexible covering that helps reduce rubbing and supports a calmer scar surface. It is different from treatment that directly changes the scar, such as an intralesional steroid injection.

Keloids can return after treatment, particularly after procedures that disturb the area. Silicone is generally considered only after the wound has closed and there is no drainage, open skin, or untreated infection.

Clean and dry the healed skin, then apply the product according to its instructions. Begin with shorter wear if the skin is sensitive, and inspect the area regularly for redness, rash, moisture damage, or worsening discomfort. Wash a reusable sheet as directed and keep it clean before reapplication.

Do not place silicone over an open wound or fresh scab. If the keloid is growing, painful, repeatedly irritated, or limiting movement, a dermatologist can discuss options such as steroid injections, laser treatment, cryotherapy, or keloid removal surgery.

Seek prompt clinical advice for increasing warmth, spreading redness, pus, fever, bleeding, or a wound that is opening. Arrange a dermatology assessment for a new or changing lump, a scar that extends beyond the original injury, or symptoms that persist despite careful silicone use.

Ask whether the scar is a keloid, whether silicone is suitable for its current stage, how to protect nearby skin, and whether another treatment should be combined with silicone.
