How can you treat a scar?
Once formed, it’s hard to get rid of the scars, however, solutions exist to improve their appearance and make them fade away. Depending of the size and depth of your scar some treatments might be more effective than others.
Topical treatments: many topical treatments are available, especially for light scars, and include easy-to-access, over-the-counter creams and solutions containing FDA-approved ingredients such as :
- Silicone that has been shown to be effective in hypertrophic scar prevention 
- Allantoin, also known to improve scar appearance .
- Dimethicone, a skin protectant commonly found in skin moisturizer especially in acne treatment .
- Dimethicone and Allantoin are two active ingredients that you will find in Mederma® Scar treatment products.
Topical treatment may also include natural extracts to provide appearance/cosmetic effects. Those natural extracts include :
- Onion extract
- Green tea
- Aloe Vera
Other topical treatments contain pharmaceutical compounds and therefore are prescription only medicines. These include:
- Imiquimod (an immune response modifier)
- mitomycin C (an antibiotic with antitumor activity)
These topical treatments have shown some effectiveness in improving the appearance and feel of scars . The sooner you start treating your scar, the more effective these treatments. The course of these treatments spans several months, but with patience and perseverance, your efforts will likely pay off.
For larger or more visible scars, you’ll probably need a more intense treatment that can only be done by a healthcare professional. These treatments are more invasive and include dermabrasion, laser treatment, micro needling, cryotherapy and filler therapy. They are not at-home treatments and require an expert opinion, so before starting any of these treatment, please choose your dermatologist carefully.
