Microneedling is a very popular non-surgical medical procedure for collagen stimulation.
During this treatment, millions of controlled micro-injuries or micro-channels are created on your skin. This stimulates the natural healing process by triggering the skin’s natural wound healing cascade. It is an amazing treatment for fine lines and wrinkles, pigmentation, scars, uneven skin texture, and stretch marks.
How does the skin respond to microneedling?
Firstly, there is injury and subsequent inflammation because of the treatment. The next stage is tissue proliferation due to the release of growth factors, increase in collagen production and new blood vessel formation. This repair process can help correct pigmentation issues in the area. Consequently, tissue remodelling occurs. During this process, the skin gets thicker and more resilient with new collagen and elastin production. Therefore, fine lines and wrinkles are diminished. As the skin gets tighter, pores appear smaller. This remodelling process can carry on for 6-12 months after a single session.
In scar tissue, the physical procedure of microneedling itself releases tight fibres of scar tissue. Thus, when tissue remodelling occurs, the skin is better and healthier without the scar.
I would never use a dermal roller for microneedling. Instead, I always use a medical microneedling device. Read on to find out why.
How does the microneedling device work?
A microneedling device is a powered device that uses single-use sterile needle cartridges. The cartridges themselves have multiple needles which the device inserts and withdraws from the skin. It can deliver thousands of micro channels within the skin every second and the whole face can be treated within 15-20minutes. The needle depth can be adjusted meaning delicate areas are treated mildly while scar tissue is needled deep.

How does the dermal roller work?
The dermal roller has multiple needles which roll over the skin while the needles make holes on the skin surface. As the needles are rolling, they can scratch the skin surface before and after puncturing the skin creating unnecessary trauma to the skin. This can set off unwanted redness and swelling of the skin. The device is at risk of contamination between uses as it is not able to be sterilised. The needles can get blunt or bend leading to unpredictable damage to the skin. There is no standard technique, meaning the pressure applied on the skin or the number of times it is rolled on the skin varies. The depth of the needles is fixed so it may be too intense for delicate areas or insufficient for others.
Why is a microneedling device better than a dermal roller ?
Microneedling devices use single-use cartridges per session therefore there is no risk of contamination. When the needle inserts the skin, it goes in perpendicularly in and out without damaging surrounding tissue. There is minimal impact on the skin’s structure. The micro-channels created during the treatment are temporary and quickly seal without leaving the skin exposed to potential external damage. The surrounding tissue is not damaged in the process. This is a physical treatment without any heat or chemical damage to the skin. Healing occurs without scarring creating better skin quality.
The device can produce significantly more micro-channels (over 70,000 per minute) compared to dermal rollers.
In conclusion, microneedling yields so many benefits to your skin from pigmentation and scars to a more youthful, healthy normal skin. The main advantage is that we are tricking your skin to repair and remodel itself without adding any external substances.
Although you will notice your skin is brighter and more radiant about 2 weeks after treatment, the magic has just begun! Read my previous blog How to get glowing skin with regular microneedling at Skin Enhance Clinic?
