So let’s begin…
What is a Derma Roller?
Derma roller is a skincare device also known as a skin needling device. The reason for such naming is that the rollers contain numerous needs to prick your skin’s surface. Besides, there’s a long handle to hold or use the roller on to your skin.
The needles remain attached to a roller. So when it’s rolled, the needles roll as well and end up pricking your skin. The length of the needles can vary depending on the usage and from type to type.

There’s a common misconception about derma rollers about injuries. Some people believe that using derma rollers on your skin might injure your body parts. But the fact is, it’s partially true. There are micro-needles attached to derma rollers. But they can’t penetrate deep into your skin.
Derma rollers just cause a micro-injury that speeds up your body’s collagen and elastin production. It increases blood circulation at the same time. This results in treating any scars on that specific part.

But what most people don’t know is that derma rollers can help with self-harm scars as well. Yes, you heard it right. If you’ve deep cuts from knives or blades, you can use derma rollers with 1-1.5mm needles to get rid of those marks.
But treating self-harm scars with derma rollers is slightly different from acne marks. And the main difference is the needle size.
In general, knives or blades cause deeper cuts in your skin cell compared to acne marks or pimples. As acne or pimple marks can be treated with only 0.2 to 0.3 mm needles, you’d at least need 1-1.5mm needles for treating self-harm cuts.
How Do Derma Rollers Help Scars?
Derma rollers are extremely famous for treating acne or any kind of scars on your body, including your face. So you might question, how does a derma roller work?

So for this, all you need to do is, use the derma roller on that specific part. Upon usage, a micro-injury will occur, and this will accelerate collagen production and blood circulation.
Finally, your skin will begin to heal naturally due to blood circulation and collagen production. And this will ultimately vanish the acne marks and provide beautiful-looking skin.
Although derma rollers are effective for treating acne or unwanted marks on your body, there’s a catch. Normally, derma rollers come with different-sized needles. The most common sizes are 0.2, 0.25, and 0.3 mm needles. If you’re looking to use derma rollers at your home for treating acne marks or accelerating blood circulation, we’d highly recommend using needles between 0.2 to 0.3mm.
However, if you want to treat self-harm marks from knives or blades, you’d at least need derma rollers with 1-1.5mm needles. In that case, it’d be risky to use them at home alone as there’ll be a high chance of deep cuts.
