To set your expectation when using a derma roller for scars treatment, multiple and continuous sessions are required to see desirable results. What a derma roller does is to heal and repair the scarring, so you’ll get a better and improved appearance of your scars that can soon fade in time. It will significantly and obviously make the skin look softer and toned so the scars can either be unnoticeable or less visible.
First, let’s enumerate and identify the different types of scars:
Keloid Scars- this scars resulted from an irregular fibrous tissue formed at the site of a scar or injury. When the body tries to repair itself aggressively after wounding, you will get raised scars due to overproduction of collagen.
Atrophic Scars- Remember your chicken pox scars? This is what an atrophic scar is- when there’s not enough tissue to fill out the skin, it leaves a pitted scar. It is the same type of scar that you get from cystic acne inflammations.
Contracture Scars- This is the type of scar caused by burns, particularly severe burns. When a part of your skin is lost during the burn, your skin contracts tightly and forms this mark.
Acne Scars- the aftermath of your acne inflammation. These scars can be shallow, deep, and can cover a wide area on your face. For complete information and guidelines on how to treat acne scars with a derma roller, please see this article.
Depending on the severity, a derma roller can help with all types of scars mentioned above except for keloid scars. Since this condition is already formed due to excessive production of collagen, dermarolling it would make the condition even worse. You may shrink a keloid scar using a dermapen but it will not completely disappear and treating it forcibly can result to infections. You still have to go through some series of other treatments that are recommended by your dermatologist. For safety reasons, do not cure keloids on your own.
