Silicone scar sheets are a non-invasive, topical approach used to improve the appearance of various scars. Made from medical-grade silicone, these sheets act as a flexible, self-adhesive barrier applied directly to the skin. They create an environment that supports the natural healing process, aiming to make scars less noticeable.
How They Work
Silicone sheets influence scar tissue through several mechanisms. A primary action is occlusion, where the sheet forms a protective barrier over the scar, reducing transepidermal water loss. This creates a moist, breathable environment, beneficial for scar remodeling. Increased hydration of the outer skin layer helps soften scar tissue, leading to a smoother, more flexible appearance.
The hydrated environment also influences collagen production, a protein that provides skin structure but can be overproduced in scars. By normalizing moisture balance, silicone helps regulate fibroblast activity, cells responsible for collagen synthesis. This regulation prevents excessive collagen formation that leads to raised scars and helps reduce scar redness and thickness. Silicone may also reduce growth factors involved in fibroblast proliferation and collagen synthesis.
Scars They Can Treat
Silicone scar sheets are effective for certain types of scars. They are a first-line treatment for hypertrophic scars and keloids. Hypertrophic scars are raised, red, and often itchy, remaining within the original injury’s boundaries. Keloids are similar but extend beyond the initial wound borders and can continue to grow.
These sheets can also be used for post-surgical scars, burn scars, and some acne scars. While most effective on newer scars, they can still improve older scars. Consistent use on mature scars reduces their thickness and improves texture.
Proper Application and Care
Consistent and proper application is essential for effective use of silicone scar sheets. Before applying, thoroughly clean the scar area and surrounding skin with mild soap and water, then dry completely. The skin must be free from creams, gels, ointments, or powders, as these interfere with adhesion.
Cut the silicone sheet to cover the entire scar. Peel off the backing and apply the sticky side directly onto the clean, dry scar, ensuring all edges adhere firmly. For optimal results, wear sheets for 12 to 24 hours daily.
For hygiene and to maintain adhesiveness, remove reusable sheets daily and gently wash with mild soap and cool water. After washing, lay the sheet flat with the adhesive side up to air dry completely before reapplication. Replace each reusable sheet when it loses its stickiness. Consistent use for 3 to 6 months is recommended for best outcomes.
