Some studies show scar improvements after use of Mederma and others show neutral or even negative results. Mederma is a brand of topical scar treatment products manufactured by Merz Pharmaceuticals of Frankfurt, Germany. Products include various formulations of gels, creams, oils, and cleansers. Mederma's marketing claims it can make scars "softer, smoother, and less noticeable" through its proprietary formulation of ten percent aqueous onion extract and one percent allantoin as active ingredients.
Onion Allium cepa extract contains several unique bioflavenoids, such as quercitin, kaempferol, and cepalin, which have proposed antioxidant and anti-inflammatory properties. It is theorized that onion extract can reduce cell proliferation during wound healing, which would decrease the risk of raised scars. In a comprehensive evidence-based review on the role of topicals and dressings in the management of skin scarring, two studies found that Mederma could improve the appearance and symptoms of wounds following shave excision of seborrheic keratoses.
However, both of these studies note that funding was provided by the manufacturer Merz Pharmaceuticals. Such sponsorship may be associated with biased results. That smooths the skin and encourages dead skin cells to slough off. Researchers think allantoin's main role is to increase the penetration of Allium cepa , aka onion. While not listed as an active ingredient, onion is a longtime additive of choice for scar treatments.
You recognize onion by its smelly sulfur-containing molecules, but it's the flavonoids quercetin and kaempferol that might improve your scar—possibly by regulating fibroblasts, the cells that help build scaffolding for new tissue.
Onion extract already includes pantothenic acid, or vitamin B5, but Mederma adds panthenol, its functionally identical alcohol, for extra oomph. The sheets are flexible and breathable, making them easy to wear throughout the day for many people. Some may not enjoy the feeling of the adhesive, and a small percentage of people may feel irritation from the adhesive.
The healing time can vary based on several factors. For fresh scars, a person may notice results in a few weeks. Older scars may take longer to heal. Derma E Scar gel is a natural choice for scar reduction. The gel contains onion bulb extract allicin, which is an antioxidant. Allantoin works to hydrate the skin.
It also contains panthenol, which is a vitamin that may help smooth skin. Together, these ingredients work to reduce the appearance of scars and improve the health of the skin. The Derma E company use natural, cruelty-free ingredients in their products, which may be important for some.
The website recommend applying the gel 2—3 times daily. Improvements may take 8 weeks to show up in fresh scars. In older scars, it may take as long as 6 months for noticeable improvements. Applying the product to any type of small, healing scars that are still pink, may show improvements in as little as 2 weeks. The MD Performance company recommend continuing to use the product even after the initial improvement until all signs of scarring are gone. Honeydew Scar Cream contains many ingredients and oils to enrich and enliven the skin.
It may be best as a long-term option for skin health and fading scars naturally. The cream contains some helpful oils, such as shea butter, rosehip oil, and jojoba oil, which may improve the look of the skin over time. Other ingredients, such as stearic acid, help protect the skin from losing moisture.
Differin Adapalene gel is a common antioxidant treatment for acne vulgaris. While it is effective for many people with this condition, it may benefit acne scarring as well. A study posted to Dermatology and Therapy notes that after 24 weeks, people with moderate to severe atrophic acne scars who used adapalene gel showed significant improvements in scarring and quality of life. These percent silicone sheets can be used to treat both new and old scars. No over-the-counter OTC product will completely eliminate old scars.
However, these are effective for flattening, softening, and fading the color of both existing and new scars. Scars vary in type and severity. Mild scars tend to lighten and fade on their own over time, becoming almost invisible.
Severe or deep scarring can require medical treatments to reduce them, such as cryosurgery, laser therapy, injections, or radiation. For scars that fall somewhere in between mild and severe, at-home treatments, including scar creams, may have benefit.
In some instances, your provider may recommend waiting up to 1 year for the scar to completely heal and mature before any treatment is attempted. In other instances, immediate treatment will be recommended. Scarring can be caused by cuts, burns, surgery, acne, and a host of other issues that affect skin. When you have a wound, your skin attempts to close itself in an effort to shield your body from germs and bacteria. This closure becomes a scar. For some people, scars, including surgery scars, reduce or fade on their own if left alone and without any special attention.
It may appear to be thicker than your regular skin, but it is, in fact, weaker. Scar tissue in a wound is formed quickly by parallel collagen fibers. If too much collagen is produced, the scar may become raised, forming a hypertrophic scar. If a significant amount of excess collagen is produced, a keloid scar may form. This type of scar grows larger than the original wound and is best checked out by a doctor.
The susceptibility of skin to form certain types of scars, such as keloids, may have a genetic link.
