Silicone Scar Sheets: How They Work, Efficacy, Side Effects

Silicone scar sheets are a popular, non-invasive scar treatment option used by healthcare professionals and individuals alike for scar management. Made from medical grade silicone, these self-adhesive sheets are designed to reduce the appearance and improve the texture of various types of scars.

How Silicone Scar Sheets Work

Silicone scar sheets work through a combination of occlusion and hydration, which together create an ideal environment for scar healing. By covering the scar with a silicone gel sheet, the area remains moist and hydrated, promoting faster healing and reducing the production of excess collagen. This process ultimately leads to flatter, softer, and less visible scars.

In addition to maintaining proper hydration, silicone scar sheets also help to regulate collagen production within the scar tissue. By providing gentle pressure and creating a barrier between the scar and the external environment, these sheets minimize the risk of overproduction or irregular arrangement of collagen fibers, which can lead to raised or discolored scars.

Benefits and Effectiveness

The benefits of silicone scar sheets are backed by numerous clinical studies and the endorsement of plastic surgeons worldwide. Some of the key advantages of these sheets over other scar treatments include:

  • Effectiveness: Numerous studies have demonstrated the efficacy of silicone scar sheets in improving the appearance, texture, and color of a wide range of scars, including surgery scars and burn scars.
  • Non-invasive: Unlike surgical scar revision or laser treatments, silicone scar sheets are a non-invasive option that can be used at home without the need for a medical professional.
  • Suitability: Silicone scar sheets are suitable for individuals of all ages and skin types, making them a versatile treatment option for everyone.
  • Pain relief: By maintaining proper hydration and providing gentle pressure, silicone scar sheets can help to alleviate itching, pain, and discomfort associated with the healing process.

Types of Scars They Can Be Used On

Silicone scar sheets have been proven effective in treating several types of scars, including:

  • Hypertrophic scars: These thick, raised scars are caused by an overproduction of collagen in the scar tissue. Silicone scar sheets help to flatten and soften these scars, making them less noticeable.
  • Keloid scars: Similar to hypertrophic scars, keloids are also caused by excessive collagen production, but they extend beyond the original wound site. Silicone scar sheets can be used as a preventative measure to minimize the risk of keloid formation and reduce the size and redness of existing keloid scars.
  • Burn scars: Burn injuries can result in thick, raised scars that are prone to itching and discomfort. Silicone scar sheets can help alleviate these symptoms and improve the appearance of burn scars.
  • Acne scars: Though primarily used for raised scars, silicone scar sheets can also provide some benefits for certain types of acne scars, particularly those with excessive collagen production or pigmentation issues.
  • Post-surgical scars: Silicone scar sheets are particularly beneficial for surgery scars, such as those from a c-section or tummy tuck. By maintaining proper hydration and promoting an optimal healing environment, these sheets help to improve the overall appearance and texture of surgical scars.

How to Use Silicone Scar Sheets

To get the most out of your silicone scar sheets, follow these steps:

  • When to start: Begin using silicone scar sheets once your wound has fully closed and there is no risk of infection. This is typically 2-4 weeks after surgery or injury, but consult with a healthcare professional to be sure.
  • How to apply: Clean and dry the scar area thoroughly. Cut the silicone sheet to fit the size of your scar, removing any backing, and press it firmly onto the scar. Ensure the entire scar is covered and the sheet adheres well to the skin.
  • Duration of treatment: Wear the silicone scar sheet for at least 12 hours per day, gradually increasing to 24 hours if tolerated. Treatment duration varies depending on the scar but typically lasts 2-3 months for new scars and up to 6 months for old scars.

Tips for best results

Keep the silicone scar sheet in place during daily activities and while showering. Clean the sheet with mild soap and water as needed, allowing it to air dry before reapplying. Replace the sheet every 7-14 days, or sooner if it loses its adhesiveness.

Side Effects

Silicone scar sheets are generally safe and well-tolerated, but there are a few potential side effects and precautions to keep in mind:

  • Skin reactions: Some individuals may experience skin irritation, redness, or itching under the silicone sheet. If this occurs, discontinue use and consult a healthcare professional.
  • Infection: Do not use silicone scar sheets on open wounds or broken skin, as this can increase the risk of infection.
  • Allergies: If you have a known allergy to silicone or any of the components in the scar sheet, avoid using this product.

There are several reputable brands that offer high-quality silicone scar sheets, including:

  • ScarAway: Known for their scar tape and scar removal sheets, ScarAway offers a variety of silicone scar products suitable for different types of scars and skin sensitivities.
  • Mederma: A popular brand in the scar treatment industry, Mederma offers advanced scar gel in addition to silicone scar sheets, providing options for both topical and adhesive treatments.
  • CicaTape: This brand specializes in clear silicone scar sheets and silicone scar strips that are both effective and discreet, making them a popular choice for facial scars or those in visible areas.

When choosing a silicone scar sheet product, consider factors such as price, size, and accessibility. Consulting with a healthcare professional can also help you determine the best product for your specific scar type and treatment goals.


Is it safe to use silicone scar sheets on sensitive skin?

Generally, silicone scar sheets are considered safe for those with sensitive skin as they are composed of medical-grade silicone, which is gentle and non-irritating. If you experience any discomfort or adverse skin reactions, stop using the sheets and seek advice from a healthcare professional.

Can old scars benefit from silicone scar sheets?

Both new and old scars can be treated with silicone scar sheets. They may be more effective on recent scars, but older scars can still experience improvements. The outcomes can vary depending on the age and severity of the scar.

What is the typical time frame to see results with silicone scar sheets?

The time it takes to see results varies from person to person and depends on the type of scar. Some individuals may notice improvements within weeks, while others might need several months of treatment. For optimal results, consistently use silicone scar sheets as directed for a minimum of 2-4 months.

Are silicone scar sheets reusable?

Yes, silicone scar sheets can be reused. You can clean them daily with mild soap and water, then allow them to air dry before reapplying. Most silicone scar sheets can be used for multiple weeks before needing to be replaced.

Are silicone scar sheets effective for all scar types?

Silicone scar sheets have demonstrated effectiveness for various scar types, such as hypertrophic scars, keloid scars, post-surgical scars, burn scars, and acne scars. However, the results may differ depending on the scar’s severity and age.

When should I replace my silicone scar sheet?

Most silicone scar sheets can be used for a few weeks before requiring replacement. If the sheet no longer adheres well to the skin or becomes damaged or overly worn, it should be replaced.

Is it possible to apply makeup over a silicone scar sheet?

Applying makeup directly over a silicone scar sheet is not recommended, as it may compromise the sheet’s occlusive properties and effectiveness. Apply makeup around the sheet’s edges, or remove the sheet temporarily when applying makeup to the scar area.

Do silicone scar sheets have waterproof properties?

Although silicone scar sheets are water-resistant, they are not completely waterproof. They can withstand mild moisture, such as sweat or light rain, but should not be submerged in water. Remove the sheet before showering or swimming, and reapply once the skin is clean and dry.

Can I engage in physical activity while wearing a silicone scar sheet?
