Silicone Scar Sheets vs. Mederma: Which Is Better for Scars?

silicone sheets vs mederma

Choosing between silicone sheets and Mederma for your scars? It’s all about finding what’s best for your skin. Each has its own way of helping your skin. Silicone sheets wrap around your scar, locking in moisture to promote smoother healing. On the flip side, Mederma’s topicals work at the surface, aiming to fade and soften the look of scars.

We’re here to walk you through both options—Mederma’s topicals and silicone sheets—to find the right match for your scar care needs. Let’s explore how each one works to help you make an informed decision.

Understanding Scars

Scars are essentially the body’s way of healing and replacing injured skin. They form when the deeper layers of your skin have been damaged and the body produces collagen fibers to repair the injury. This process, while crucial for healing, often results in a scar that looks and feels different from the surrounding skin.

There are several common types of scars: surgical scars from operations, acne scars from severe acne, and injury scars from cuts, burns, or other trauma. Each type results from a different cause and can vary in appearance and texture, making the choice of treatment important for effective healing and appearance improvement.

What are Silicone Sheets?

Silicone sheets are a widely used scar treatment option made from medical-grade silicone. They’re thin, flexible layers that you apply directly over your scar. When in place, they create a protective barrier that helps keep the scar area hydrated. This moisture prevents the scar tissue from drying out and becoming too hard, which can make scars more noticeable.

Since 1983, silicone sheets have been effectively used to treat two types of scars: hypertrophic scars, which are thick and raised but don’t go beyond the original wound, and keloids, which are overgrown scars that spread outside the wound area.

How do they work? By locking in moisture and protecting the scar from bacteria and other external factors, silicone sheets help normalize the production of collagen. This can lead to scars becoming flatter, softer, and less red over time.

The benefits of using silicone sheets for scars include:

  • Reduced scar appearance: They can make scars less visible.
  • Non-invasive treatment: Silicone sheets offer a gentle way to improve scars without the need for surgery or prescription medications.
  • Easy to use: They can be cut to fit the size of your scar and are simple to apply and remove.
  • Reusable: Many silicone sheets can be washed and reused, making them a cost-effective option.
  • Comfortable: Silicone sheets are soft and flexible, making them comfortable to wear for extended periods, even under clothing.

Overall, silicone sheets provide a safe and effective method for managing scars, with many users reporting positive results in terms of both the appearance and texture of their scars.

What is Mederma?

Mederma is a widely recognized brand in scar treatment, known for its range of products designed to improve the appearance of scars. The key ingredient in Mederma products is Cepalin, a botanical extract derived from onions, which has been touted for its healing properties. Mederma comes in various forms, including gels and creams, catering to different needs and preferences. However, recently the brand has expanded their product range to also offer silicone scar sheets.

The working principle behind Mederma’s topicals involves the application of its active ingredients directly onto the scar. These ingredients aim to soften, smooth, and reduce the discoloration of scars over time. Mederma is particularly noted for its ease of use, with most products requiring application only once or twice a day.

Benefits of using Mederma’s gel or cream for scars include:

  • Improved Scar Appearance: Regular use can lead to scars that are less noticeable.
  • Versatility: Suitable for many types of scars, including those from surgeries, injuries, acne, and burns.
  • Ease of Use: Simple application process, which fits easily into daily skincare routines.
  • Non-Greasy Formula: Mederma’s gel and cream are designed to absorb quickly without leaving a residue, making it comfortable for everyday use.

Mederma is favored by many for its effectiveness in reducing the overall visibility of scars, making it a go-to option for those looking to minimize the appearance of their scars without invasive treatments.

Comparing Silicone Sheets and Mederma

When choosing between silicone sheets and Mederma for scar treatment, understanding their differences can help you decide which is best for your needs.

Mechanism of Action

Silicone scar sheets create a protective, hydrating barrier over the scar, encouraging a balanced collagen production and preventing the scar from becoming overly raised or discolored. This moist environment promotes natural healing processes.

On the other hand, Mederma uses an onion extract, Cepalin, to reduce inflammation and promote healing. It works by softening and smoothing the scar, gradually diminishing its appearance. Mederma is absorbed into the skin, directly targeting the scarred area with its active ingredients.

Usage and Application

For the best results, silicone sheets should be applied to the scar for 12-24 hours a day. They are reusable, often recommended for continuous use over several weeks to months, depending on the scar’s condition.

In contrast, Mederma gel or cream is applied once or twice daily, directly onto the scar. The duration of use varies, with many users seeing improvements within 4 to 8 weeks for newer scars and 3 to 6 months for older scars.


Silicone scar sheets work well for both new and older scars. They’re really good for new scars, but older scars can get better too. The results might change depending on how old and what kind of scar you have. Silicone sheets help keep scars moist, which stops them from getting too hard and noticeable (Source: Advanced Cosmetic Surgery).

Mederma, known for its onion extract, has been compared to other scar treatments. Studies show that Mederma can make old and new scars look better compared to not treating them at all. However, it’s not necessarily better than other common treatments. When onion extract is mixed with silicone, it tends to work better. But, Mederma might also cause more side effects compared to other treatments or no treatment.

Research says silicone gels or sheets and taping scars might help, but the proof isn’t very strong. So, even though lots of products claim to fix scars, there’s not much strong evidence to back them up.

When picking a scar treatment, it’s best to talk to a doctor or dermatologist. They can help you choose the right one based on what the science says and what your scar is like.

Side Effects and Considerations

Silicone Sheets rarely cause side effects, but some individuals may experience skin irritation or discomfort under the sheet. It’s important to keep the area clean to avoid any skin issues.

Mederma is generally well-tolerated but some users may experience mild skin irritation or allergic reactions due to its active ingredients. Performing a patch test before regular use is advisable.

Cost Comparison

The initial cost of silicone sheets is higher, but their washable and reusable nature may offer long-term cost-effectiveness for ongoing treatment needs. Mederma, being less expensive upfront, might lead to higher cumulative costs for continuous application over larger scars or extended periods.

Deciding between silicone sheets and Mederma involves weighing these factors based on personal scar characteristics, preferences, and lifestyle. Each has its strengths, and their effectiveness can vary, underscoring the importance of choosing the option that best aligns with individual healing goals.

Which One Is Better?

Deciding which scar treatment is better, silicone sheets or Mederma, isn’t a one-size-fits-all answer. It depends on several factors, including the type of scar, where it’s located, and personal preferences.

For raised scars, like keloids or hypertrophic scars, silicone sheets often take the lead. Their ability to form a protective barrier that maintains moisture can directly address the excess collagen that makes these scars raised. They’re especially useful for large areas or scars that are under tension, such as joints.

Mederma, with its key ingredient Cepalin, might be the go-to for scars that are more about discoloration than raised texture. It’s a favorite for facial scars or those in visible areas where a sheet might be inconvenient. Its gel or cream form is easy to apply and can be less noticeable, making it a practical choice for daily use.

Location plays a role too. Silicone sheets are great for parts of the body where they can stay in place, but for areas that move a lot or where adhesion is tricky, Mederma’s ease of application shines.

User preference is another key factor. Some people find the idea of a gel or cream more appealing and easier to integrate into their skincare routine. Others appreciate the set-it-and-forget-it nature of silicone sheets, especially since they can be worn overnight or under clothing.

In essence, if you’re dealing with a raised, textured scar, especially in less visible areas or over larger surfaces, silicone sheets might offer the best benefits. For scars that are more about coloration changes or are located in highly visible areas, Mederma could be your ally.

Ultimately, the best choice aligns with your specific needs, lifestyle, and the scar’s characteristics, making a consultation with a healthcare provider a wise step to tailor your treatment plan.


In summary, both silicone sheets and Mederma bring their own strengths to the table when it comes to scar treatment. Silicone sheets are particularly useful for raised scars and covering larger areas, helping to prevent the overproduction of collagen. Mederma, known for targeting discoloration and being suitable for visible, sensitive areas, should be chosen with a bit more caution due to potential side effects, including skin irritation for some users.

The choice between these treatments should consider not only the type and location of the scar but also your personal preferences and how you live your life. Above all, the importance of consulting with a healthcare professional cannot be overstated. They can provide guidance tailored to your unique situation, taking into account the latest research and potential risks associated with each option. This ensures that your scar treatment plan is not only effective but also safe for your specific skin needs.
