Dermaroller skin rejuvenation

About the procedure

Medical Skin Needling, also referred to as Collagen Induction Therapy (CIT) and Micro-Needling, is considered to be a relatively new concept within the plethora of aesthetic treatment options available for skin rejuvenation. It stimulates the body’s own collagen production to reduce the appearance of fine lines and wrinkles, stretch marks, skin laxity and scarring such as that caused by acne or chicken pox.

Dermaroller™

The Dermaroller™ device originates from Germany and was first commercialised in 2005. It was the first such device to be given a European CE mark classification as a medical device and is also licensed in the USA.

During the procedure pin-point bleeding on the surface of the skin should be achieved as capillaries are punctured. The Dermaroller™ results in natural skin rejuvenation and repair as it stimulates the body’s own collagen production, cell proliferation and angiogenesis. The Dermaroller™ micro-surgical needle puncture creates disruption of dermal cells and tissue and will puncture dermal capillaries, this creates sufficient trauma to stimulate the initial stages of the wound healing process.

It is becoming increasingly recognised that changes in the electrical potential of skin cells that occur during times of trauma and the resulting nerve signals play a key part in stimulating fibroblast activity and endothelial cell proliferation.

The Dermaroller™ micro-surgical needle has its own electrical charge and in independent studies it has been shown that it reduces the skin electrical resistance and that the reduction is proportional to the length of the needle. Therefore in addition to physical trauma and the initial platelet derived growth factors, it is believed that the change of polarity induced by the Dermaroller™ will work in synergy and enhance the initial fibroblast proliferation and activity.

Also given the absence of significant physical tissue damage it is believed that the wound healing process can move more quickly to the proliferation stage and that the new collagen, the new endothelial cells and the regenerated extracellular matrix that are produced will be integrated into the existing dermal architecture without the fibrous and connective tissue that can be observed in scar tissue.

In addition the Dermaroller™ procedure does not cause the thermal damage to the tissue associated with laser and radio-frequency procedures and as a result it is believed by the manufacturers that Dermaroller™ can encourage greater angiogenesis than these procedures.
