Microneedling and the skin


As the Microneedling machine glides over the skin, microscopic punctures are lightly stamped in the skin’s matrix stimulating an inflammatory, or wound healing response.  This promotes the most intense repair, renewal and skin rejuvenation. Natural growth factors are released to stimulate reformation and depositing of fresh collagen.  Unlike most rejuvenation treatments a derma pen can target 3 main cell types.


Keratinocytes: The main cells of the epidermis formed by cell division at its base. New cells continually move towards the surface. As they move, they gradually die and become flattened.


Corneocytes: The flattened dead keratinocytes that together make up the very outer layer of the epidermis, this layer is constantly worn away or shed


Melanocytes: Produce the pigment melanin that protects against UV radiation and gives the skin its color.


Fibroblasts: Fibroblasts produce tropocollagen, which is the forerunner of collagen, and ground substance, an amorphous gel-like matrix that fills the spaces between cells and fibers in connective tissue.


When the pen punctures these areas of the epidermis scar less wound healing is being promoted reducing the risk of irregular collagen deposition.

As the skin is made up of 3 layers, each layer contains major cells groups.  The dermis and the epidermis are the key skin layers to be targeted.
