Scars, whether from surgery, injury, burns, or acne, can be a source of discomfort and self-consciousness. Over time, numerous treatments and products have emerged, claiming to reduce or eliminate these marks. Among these, Mederma has gained significant attention. This article will explore whether Mederma can effectively remove 10-year-old scars, examining its ingredients, mechanisms, efficacy, and alternatives.
Understanding Scars
What Are Scars?
Scars are areas of fibrous tissue that replace normal skin after an injury. They form as part of the body’s natural healing process. When the skin is wounded, the body creates new collagen fibers to mend the damage, resulting in a scar. The final appearance of a scar depends on various factors, including the size and depth of the wound, its location, the person’s age, genetics, and skin type.
Types of Scars
Atrophic Scars: These are sunken scars that develop when underlying structures supporting the skin, such as fat or muscle, are lost. They are often associated with conditions like acne or chickenpox.
Hypertrophic Scars: These are raised and red scars that stay within the boundaries of the original injury.
Keloid Scars: These are raised and extend beyond the original injury site, often becoming much larger than the wound itself.
Contracture Scars: These occur when the skin tightens after a burn, which can impair movement.
Understanding the type of scar is crucial in determining the most effective treatment approach.
Mederma
What is Mederma?
Mederma is a topical gel widely used for scar treatment. It’s manufactured by Merz Pharmaceuticals and is available over-the-counter. The product is designed to improve the appearance of scars resulting from various sources, including surgery, injuries, burns, and acne.
Ingredients in Mederma
The key ingredients in Mederma include:
Allium Cepa (Onion) Bulb Extract: Known for its anti-inflammatory and antibacterial properties, onion extract is believed to help reduce scar formation and discoloration.
Aloe Vera: Renowned for its soothing and moisturizing properties, aloe vera can aid in skin repair and regeneration.
Allantoin: This compound promotes cell regeneration and has a moisturizing effect, helping to soften and smooth the skin.
Hyaluronic Acid: Known for its hydrating properties, it helps to keep the skin moist and can improve texture.
These ingredients work together to enhance the skin’s healing process and improve the overall appearance of scars.

How Mederma Works
Mechanism of Action
Mederma works through several mechanisms:
Moisturization: Keeping the scar area hydrated is crucial for healing. Mederma’s moisturizing agents, such as hyaluronic acid and allantoin, help to soften the scar tissue and make it more pliable.
Anti-Inflammatory Properties: The onion extract in Mederma has anti-inflammatory properties that can reduce redness and swelling associated with scars.
Cell Regeneration: Allantoin promotes the regeneration of skin cells, which can help to improve the texture and appearance of the scar.
Color Correction: Regular application of Mederma can help to even out the skin tone around the scar, reducing discoloration.
Application Instructions
For optimal results, Mederma should be applied as follows:
Clean the Area: Ensure the scar area is clean and dry.
Apply a Thin Layer: Gently massage a small amount of Mederma onto the scar.
Frequency: Apply the gel once daily. For older scars, consistent application for several months may be necessary.
Adhering to these instructions is crucial for achieving the best possible outcomes.
Efficacy of Mederma on Old Scars
Scientific Studies
Several studies have been conducted to evaluate the effectiveness of Mederma in treating scars. A few noteworthy ones include:
Study on Post-Surgical Scars: A study published in the “Journal of Cosmetic Dermatology” found that Mederma improved the appearance of post-surgical scars when used consistently over several months.
Comparative Studies: Research comparing Mederma to other treatments, such as silicone gel sheets, has shown mixed results. Some studies suggest that while Mederma is effective, silicone gel sheets may offer superior results for certain types of scars.
User Experiences and Testimonials
Many users have reported positive outcomes with Mederma, particularly for newer scars. However, the effectiveness on older scars, such as those 10 years old, varies widely. Factors influencing results include the type and severity of the scar, the individual’s skin type, and adherence to the application regimen.
Clinical Limitations
Varied Results: The effectiveness of Mederma on 10-year-old scars can be inconsistent. Some users may see significant improvement, while others may notice minimal changes.
Duration of Use: Older scars generally require longer treatment periods. It’s not uncommon for users to need six months or more of consistent application to see noticeable results.
Skin Type and Scar Type: Certain skin types and scar types (e.g., keloid scars) may not respond as well to Mederma.
Alternative Treatments for Old Scars
Silicone Gel Sheets
Silicone gel sheets are often recommended by dermatologists for scar treatment. They work by hydrating the scar tissue, reducing collagen production, and flattening raised scars. Clinical studies have shown that silicone gel sheets can be highly effective for both new and old scars.
Laser Therapy
Laser therapy can be used to treat a variety of scars, including those that are several years old. Different types of lasers can target pigmentation, redness, and raised scar tissue. This treatment is typically performed by a dermatologist or plastic surgeon and may require multiple sessions.
Microneedling
Microneedling involves using tiny needles to create micro-injuries in the skin, stimulating collagen production and promoting the healing of scar tissue. This treatment can be effective for atrophic and acne scars and can improve the texture and appearance of older scars over time.
Chemical Peels
Chemical peels involve applying a chemical solution to the skin to exfoliate the top layers, promoting the growth of new, healthier skin. They can be beneficial for superficial scars and hyperpigmentation. However, they are less effective for deeper or raised scars.
Steroid Injections
For hypertrophic and keloid scars, steroid injections can help reduce inflammation and flatten the scar. This treatment is typically performed by a healthcare professional and may require several sessions.
Surgical Options
In some cases, surgical revision of a scar may be the most effective option. This involves removing the old scar tissue and re-closing the wound in a more controlled manner. Surgical options are generally considered for severe scars that have not responded to other treatments.
Combining Treatments
Combining different treatments can often yield the best results for old scars. For example, using Mederma in conjunction with silicone gel sheets or undergoing laser therapy followed by topical treatments can enhance the overall outcome. Consulting with a dermatologist can help determine the most effective combination of treatments based on individual needs and scar characteristics.
Preventing New Scars
While treating old scars is challenging, preventing new scars from forming is equally important. Some strategies include:
Proper Wound Care: Keeping wounds clean, moist, and covered can promote better healing and reduce the risk of scarring.
Sun Protection: Protecting healing skin from the sun can prevent hyperpigmentation and improve the appearance of scars.
Avoiding Trauma: Minimizing trauma to the healing area can prevent the formation of more pronounced scars.
Conclusion
Mederma is a popular and accessible option for scar treatment, known for its moisturizing and anti-inflammatory properties. While it can be effective in improving the appearance of scars, its efficacy on 10-year-old scars varies. Factors such as the type and severity of the scar, the individual’s skin type, and adherence to the treatment regimen all play a role in the outcome.
