Benefits of Silicone for Old Scars: A Complete Overview

by Ella

Scars are a natural part of the body’s healing process, forming as a result of injuries, surgeries, or skin conditions. While scars may fade over time, some individuals may be concerned about the appearance of old scars and seek ways to improve their texture and visibility. Silicone-based products have gained popularity as a potential treatment for scar healing, especially for old scars. In this article, we will explore the use of silicone for scar healing, the science behind its effectiveness, and its potential benefits for improving the appearance of old scars.


1. The Nature of Scars:

Scars form when the body repairs and replaces damaged skin tissue. The process of scar formation can vary depending on the depth and severity of the injury, as well as individual factors like genetics and skin type. Initially, scars may appear red, raised, or discolored, but they tend to fade and flatten over time as the healing process continues.


Old scars are those that have undergone maturation, which typically occurs within the first year of the injury or surgery. At this stage, scars may become less noticeable but might still be a concern for some individuals due to their appearance.


2. Understanding Silicone and Scar Healing:

Silicone-based products, such as silicone gels and sheets, have been used for decades to aid in scar healing. Silicone is a polymer that creates a semi-occlusive barrier when applied to the skin, helping to retain moisture and enhance the overall healing process. The use of silicone in scar management is supported by various studies and clinical trials, making it a popular option for both healthcare professionals and individuals seeking scar improvement.


3. How Does Silicone Work on Scars?

The mechanism behind silicone’s effectiveness in scar healing is not yet fully understood, but several hypotheses explain its benefits:

a) Moisture Regulation: Silicone creates a semi-occlusive environment on the scar, which helps regulate moisture levels. Maintaining optimal hydration at the scar site may improve the skin’s overall appearance and texture.

b) Collagen Regulation: Silicone may influence collagen production and organization during the scar formation process. Collagen is a key component of the skin’s structure, and proper alignment and distribution can lead to smoother and less noticeable scars.

c) Anti-Inflammatory Effects: Silicone has been shown to exhibit anti-inflammatory properties, which can help reduce redness and swelling associated with scar tissue.

d) Reducing Irritation: Silicone forms a protective barrier over the scar, preventing friction and irritation from clothing and other external factors that may impede the healing process.

4. Benefits of Silicone for Old Scars:

When it comes to old scars, silicone-based products can offer several potential benefits:

a) Improved Texture: Silicone helps soften and flatten scars, potentially leading to a smoother texture and less prominent appearance.

b) Reduced Redness and Discoloration: Silicone’s anti-inflammatory effects may help diminish redness and discoloration associated with old scars.

c) Enhanced Flexibility: Old scars may be less flexible than surrounding skin, leading to discomfort and limited mobility. Silicone can promote the flexibility of scar tissue, contributing to greater comfort and range of motion.

d) Non-Invasive Option: Silicone gels and sheets are non-invasive and easy to apply at home, making them a convenient option for scar management.

5. Using Silicone for Scar Healing:

Silicone-based products are available in various forms, including gels, sheets, and ointments. When using silicone for scar healing, it’s essential to follow these guidelines:

a) Start Early: The sooner you begin using silicone on a healing scar, the better the potential outcomes. However, silicone can still provide benefits for old scars, even if the scar has matured.

b) Consistency is Key: For optimal results, apply silicone gel or sheets consistently as directed by the product’s instructions. Most silicone products recommend daily use for several months.

c) Clean and Dry Skin: Before applying silicone, ensure that the scar area is clean and dry to maximize product adherence.

d) Patience: Scar improvement takes time, and results may vary from person to person. Be patient and consistent in your use of silicone-based products to observe potential benefits.


Silicone-based products have demonstrated effectiveness in scar healing and have become a popular choice for improving the appearance of old scars. Their ability to regulate moisture, influence collagen production, reduce inflammation, and create a protective barrier makes them valuable tools in scar management. By using silicone gels or sheets consistently and starting early in the healing process, individuals may experience improved scar texture, reduced redness, and enhanced flexibility.

While silicone can be a beneficial treatment for old scars, it’s essential to have realistic expectations and remember that scar healing is a gradual process that varies from person to person. For those with concerns about old scars, seeking guidance from a healthcare professional or dermatologist can provide valuable insights and personalized recommendations for scar management. With proper care and attention, silicone can play a pivotal role in improving the appearance and texture of old scars, ultimately boosting confidence and well-being.
