Microneedling (Dermaroller & Dermapen)

one name, many treatments - but not all treatments are equal

Microneedling is the umbrella term for a variety of different treatments that are designed to reduce the appearance of skin damage such as scarring, dark marks, sun damage and ageing. Very small needles cause tiny punctures in the skin; these small wounds encourage the body’s natural healing response and renew the skin cells. As the skin repairs itself the production collagen and elastin is triggered to give an almost immediate plumped and rejuvenated effect.

At The Harley Medical Group we provide two of the most highly regarded microneedling treatments Dermaroller and Derma FNS.

Micro-needling and how it works

Though only very thin, the skin is made up of three layers: epidermis, dermis, subcutaneous. By penetrating the epidermis with very fine small needles collagen production is increased at the body heals itself. 

Though only tiny, each wound will go through the three stages of healing: 

  • Inflammation
  • Proliferation (tissue formation)
  • Tissue remodelling

The epidermis in penetrated the puncture closes in minutes and will heal relatively quickly; though minute the wound created does cause localised damage and bleeding. During the treatment the practitioner may use a serum; this will depend on the form on miconeedling conducted. When the tiny blood vessels are ruptured blood cells and serum are spread into the surrounding tissue. 

The leucocytes (white blood cells) act on the damaged tissue, remove debris and kill bacteria. This reaction produces a surge of activity that leads to the Fibroblasts being “instructed” to produce more collagen and more elastin.

A few days after the treatment the epidermal cells (keratinocytes) begin reproducing and the epidermis becomes thicker.  Over the following months the skin will progressively tighten as the collagen slowly shortens and becomes more supported. 


Dermaroller is a titanium device that is rolled over the skin to create thousands of tiny contact points. This causes the body to create a wound healing process for rejuvenated, smoother and younger looking skin.

Derma FNS

Derma FNS (Fractional Needling System) uses a unique electronic mechanism which allows the practitioner to control the intensity to tailor the treatment for the best results. When combined with a highly effective serum and a soothing aftercare cream, the treated area will see significant improvements to the damaged skin.
