Effective Scar Care After Surgery: Can Mederma Gel Help? - Plastic Surgery

How to take care of a scar?


Dear Doctor: Regarding the care of surgical scars, in addition to using silicone sheets or beauty gels within six months, is it appropriate to also use Mederma gel (manufactured in Frankfurt, Germany)? The scar is still in an active state with redness, swelling, itching, and pain.
Is it suitable to use a gel that contains anticoagulants? Thank you.

Dr. Zhou Hongzhang reply Plastic Surgery


Care for surgical scars should include: 1.
Sun protection; 2.
Use of whitening creams (including hydroquinone) or low-potency corticosteroids (to be used cautiously due to potential side effects); 3.
Pressure therapy, which may involve silicone sheets, cosmetic gels, paper tape, or wearing headgear and elastic garments; 4.
Physical rehabilitation therapy to prevent scar contracture, such as the use of splints or orthotics.
There are many scar ointments available on the market, most of which contain multiple ingredients.
While they are not ineffective, their effectiveness is often exaggerated.
It is recommended to combine these treatments with physical rehabilitation and pressure therapy to achieve optimal results.
Anticoagulants may help reduce bruising, but their efficacy is unclear.

Effective scar care after surgery is crucial for optimal healing and minimizing the appearance of scars. When considering the use of Mederma gel in conjunction with artificial skin or silicone sheets, it is important to understand the properties and intended use of these products.

Mederma gel is a topical treatment specifically designed for scar management. It contains allantoin, which is known for its moisturizing properties, and onion extract, which has been shown to help improve the appearance of scars. The gel is typically recommended for use on mature scars, but it can also be beneficial for newer scars, especially when they are in the healing phase. However, it is essential to note that Mederma should not be applied to open wounds or actively healing skin, as this could lead to irritation or adverse reactions.

In your case, since the scar is still in an active state—characterized by redness, swelling, itching, and pain—it's advisable to wait until the wound has sufficiently healed before applying Mederma. The active ingredients in Mederma may not be effective on an open or inflamed scar, and using it prematurely could potentially exacerbate irritation.

Regarding the use of artificial skin or silicone sheets, these products are designed to create a protective barrier over the scar, helping to maintain moisture and reduce tension on the skin. They can be beneficial in the early stages of healing and can be used simultaneously with Mederma once the scar has stabilized. However, it is crucial to avoid layering products that may cause excessive moisture or irritation.

As for the use of anticoagulant gels, these are typically used to manage bruising and swelling. While they may help reduce the appearance of bruises, their effectiveness on scar healing is less clear. Anticoagulants can thin the blood and may not be suitable for use on open or healing wounds, as they could increase the risk of bleeding or hematoma formation. Therefore, it is generally not recommended to use anticoagulant gels on active scars without consulting a healthcare professional.

In summary, for effective scar care after surgery, consider the following steps:
1. Wait for Healing: Allow the scar to heal adequately before applying Mederma or any other topical treatments. Ensure that the skin is no longer open or inflamed.

2. Use Protective Barriers: Continue using artificial skin or silicone sheets to protect the scar and maintain moisture. These can be beneficial during the initial healing phase.

3. Consult a Professional: Always consult with your healthcare provider or a dermatologist before combining treatments, especially if you are considering using products like anticoagulant gels on an active scar.

4. Follow a Comprehensive Scar Management Plan: Incorporate sun protection, pressure therapy, and possibly physical therapy into your scar care regimen for optimal results.

5. Monitor for Changes: Keep an eye on the scar's appearance and any changes in symptoms. If the scar remains red, swollen, or painful, seek medical advice to rule out complications.

By following these guidelines and working closely with your healthcare provider, you can enhance your scar healing process and achieve the best possible cosmetic outcome.
