Mederma is a popular over-the-counter treatment designed to improve the appearance of scars. It is widely used and recommended by dermatologists and plastic surgeons for its efficacy in scar treatment. This article delves into the science behind Mederma, its active ingredients, effectiveness, user reviews, clinical studies, and how it compares to other scar treatments.
What is Mederma?
Overview
Mederma is a topical gel or cream used to reduce the appearance of scars. It is manufactured by Merz Pharmaceuticals and is available in various formulations, including Mederma Advanced Scar Gel, Mederma PM Intensive Overnight Scar Cream, and Mederma for Kids.
Types of Scars Treated
Mederma is marketed as effective for various types of scars, including:
Surgical Scars: Resulting from medical procedures.
Injury Scars: From accidents or wounds.
Burn Scars: Caused by heat, chemicals, or radiation.
Acne Scars: Resulting from severe acne.
Stretch Marks: From pregnancy, weight changes, or growth spurts.
Active Ingredients
Cepalin (Onion Extract)
Cepalin is the proprietary botanical extract derived from onions and is the primary active ingredient in Mederma. Onion extract is known for its anti-inflammatory, antibacterial, and collagen-regulating properties, which can help in scar treatment.
Allantoin
Allantoin is another key ingredient found in Mederma formulations. It is known for its moisturizing and keratolytic (exfoliating) properties, which help to soften and smooth the skin, promoting the healing of scars.
Other Ingredients
Mederma products may also contain other ingredients such as hyaluronic acid, which helps to hydrate the skin, and various vitamins and antioxidants that support skin health.
How Does Mederma Work?
Mechanism of Action
Mederma works through several mechanisms to improve the appearance of scars:
Anti-inflammatory Effects: Reduces inflammation in the scar tissue, which can help flatten and smooth scars.
Collagen Regulation: Modulates collagen production, preventing excessive scar tissue formation.
Moisturization: Keeps the scar tissue hydrated, making it more pliable and less noticeable.
Exfoliation: Promotes the removal of dead skin cells, encouraging new skin growth.
Application Process
To achieve the best results, Mederma should be applied as follows:
Clean the Area: Wash the scar and surrounding skin with mild soap and water.
Apply a Thin Layer: Gently massage a small amount of Mederma into the scar.
Frequency: Apply once daily (Mederma Advanced) or as directed by the specific product’s instructions.
Consistency: Use consistently for several weeks to months, depending on the scar’s age and severity.
Clinical Studies and Effectiveness
Clinical Evidence
Several clinical studies have evaluated the effectiveness of Mederma in improving the appearance of scars:
Study on Surgical Scars: A double-blind study found that patients using Mederma on surgical scars showed significant improvement in scar softness, redness, and overall appearance compared to those using a placebo.
Study on Acne Scars: Research indicated that Mederma helped reduce the appearance of acne scars, improving skin texture and color.
Study on Stretch Marks: Clinical trials have shown mixed results, with some users reporting a reduction in the appearance of stretch marks, while others saw minimal improvement.
User Reviews
User reviews of Mederma are generally positive, with many individuals reporting noticeable improvements in scar appearance. Common feedback includes:
Improved Texture: Users often note that scars become softer and smoother.
Reduced Redness: Many report a decrease in scar redness and discoloration.
Timeframe: Some users see results within weeks, while others require several months of consistent use.
Comparing Mederma to Other Scar Treatments
Silicone Gel Sheets
Silicone gel sheets are a popular alternative to Mederma. They work by providing a protective barrier over the scar, maintaining moisture and reducing collagen production. Studies suggest that silicone gel sheets can be as effective, if not more so, than Mederma in reducing scar visibility.
Prescription Treatments
For more severe scars, prescription treatments such as corticosteroid injections, laser therapy, or prescription-strength topical treatments may be recommended. These options can be more effective but also come with higher costs and potential side effects.
Natural Remedies
Natural remedies like aloe vera, vitamin E, and honey are commonly used for scar treatment. While these can provide some benefits, clinical evidence supporting their effectiveness is limited compared to Mederma.
Potential Side Effects and Precautions
Side Effects
Mederma is generally well-tolerated, but some users may experience:
Skin Irritation: Redness, itching, or rash at the application site.
Allergic Reactions: Rarely, users may experience an allergic reaction to one of the ingredients.
Precautions
Patch Test: It is recommended to performa patch test on a small area of skin before using Mederma extensively.
Avoid Open Wounds: Do not apply Mederma to open wounds or unhealed skin.
Sun Protection: Protect treated areas from excessive sun exposure, as UV rays can worsen scar appearance.
How to Maximize Results with Mederma
Consistent Use
Consistency is key when using Mederma. Regular application, as directed, over several weeks or months is essential for optimal results.
Combination Therapy
Combining Mederma with other treatments, such as silicone gel sheets or laser therapy, can enhance scar reduction.
Sun Protection
Using sunscreen on scars can prevent them from becoming darker and more noticeable. Look for a broad-spectrum sunscreen with an SPF of at least 30.
Healthy Lifestyle
Maintaining a healthy lifestyle, including a balanced diet rich in vitamins and minerals, staying hydrated, and avoiding smoking, can support overall skin health and improve scar healing.
