How does Derma Roller Work?
Easily Induce Collagen Production by 1,000%
If you want to know how does derma roller work, then you are in luck!. You won’t find many ways to rejuvenate your skin. The best method is actually to cause yourself a minor skin injury so that your body will immediately start to work to repair it, replacing your old skin with new skin.
This is actually the main principle behind dermarolling (a.k.a. Microneedling). Herein the injury to your skin will be serious enough to trigger its healing process but not serious enough to cause any permanent damage.

Derma Roller System Vs Laser Treatment
Microneedling is the same principle that lies behind most invasive skin rejuvenating methods (e.g. laser treatments, chemical peels) today. For instance, with laser treatments the top layer of your skin will either be completely evaporated or in the case of “fraxel lasering,” only part of the skin evaporates.
With the derma roller micro injuries (small vertical channels in the dermis layer of your skin) are mechanically created. The difference between how the dermaroller treatment and fraxel laser work is that the fractional laser creates these micro injuries thermally and have ugly side effects.
Nevertheless, the principle is still the same. Both methods will result in collagen production except dermarolling has very little side effects, and it can induce collagen growth by 1,000% in 1 single treatment.
Concept Behind Microneedling
Whenever you sting yourself with a needle you’re mechanically damaging some of your skin’s cells. They will become too damaged to properly function so your body will immediately begin replacing them with healthy, new cells. Based upon this principle, dermarolling will speed up the process while also diminishing things like pigmentation, age spots and post-acne spots.
The top layer of your skin is known as the epidermis. It is between .05 and .2mm thick depending upon where it’s located. Underneath the epidermis is the dermis, which is between .5mm thick (underneath your eyelids) and 2mm (on your back) thick.
Dermis is the layer that you need to reach if you want to stimulate collagen production. With a .5mm derma roller you’ll be able to reach the dermis and stimulate cell renewal. This will improve your skin’s overall texture and tone.
If you’re using a derma roller that’s shorter than .5mm you’ll enable your skin care products to penetrate your skin better, while also improving really shallow pigmentation and thickening your epidermis.
How Does Derma Roller Work on Scars and Stretch Marks
Typically, scar tissue (whether it’s raised, flat or indented) is abundant in collagen. However, it’s important to understand that scar collagen is thick and woven with a different pattern than your normal skin’s pattern. These are the only differences between scar tissue and your normal skin though.
Whenever you crush the scar tissue the scar pattern’s fibers will also be crushed. The body will then regenerate this into a smoother, softer scar that looks better. If the scar tissue isn’t broken, then your body won’t put any effort into fixing it.
Instead, it will simply view the scar as a “cosmetic problem” that doesn’t need fixed. Applying microneedling to that skin will trigger the healing process because your body will see this skin as broken, even though the tiny pricks don’t cause significant damage. Unfortunately, your body won’t bother with completely replacing this scar tissue with normal skin, especially if the scar is deep. However, what it will do is produce a scar that will look better.
Simply put, dermarolling triggers a healing process. Your body will then heal the area by producing more collagen by 1,000%. What will typically happen is that indented scars will fill themselves in while raised scars will become flat. While this doesn’t always work, it does usually work.
Acne scars don’t have a lot of scar tissue. They are what’s known as “atrophied,” meaning that they’re actually missing tissue. Whenever you are using a dermaroller or derma stamp pen, they will slowly or partly fill in with collagen. This is also true for wrinkles.
It’s also important to understand that needling a hypo-pigmented scar facilitates melanocytes (the cells that are responsible for producing skin-pigment) to move from surrounding skin into the scar to improve the coloring there.
Why Dermarolling is More Advantageous than Other Methods
Dermarolling creates micro-punctures or micro-channels in your skin without actually removing any layers of skin since other methods do remove layers of skin. This is why your skin will heal so quickly and it is also why you’ll be less prone to develop an infection or have any complications, thus you’ll have a very short downtime.
With dermarolling it is possible to go really deep into your skin, up to 2mm. Going to such depths with other ablative methods (e.g. acid peels, ablative lasers) could case scarring or serious damage to your skin because the laser will physically evaporate part of your skin, thus removing it. On the other hand, needle will only penetrate your skin without damaging the surrounding areas.
Some of the other major benefits to this microneedle treatment include the fact that dermarolling:
- Won’t heat up your skin. Lasers and IPL will heat up your skin, making it prone to collateral damage (e.g. burns, hyper-pigmentation, hypo-pigmentation, scarring).
- Is cheaper than other methods.
- Will actually make your skin thicker.
- Can be used anywhere on your body except for your upper eyelids and directly beneath your lower eyelashes where it could cause injury to your eye. However, you can use it on those areas where you have thin skin (e.g. your neck, the top of your hands).
- Will greatly enhance the absorption and efficacy of your skin care products. Our skin is typically impenetrable but with dermarolling the skin becomes temporarily permeable for all skin care products by 10,000 times.
