Dermaroller
A derma roller is a cylindrical drum shape surrounded by microneedles. The device creates superficial breaks in the skin when rolled upon it.
It stimulates the growth of collagen fibers below the skin.
How microneedling products work
Microneedling results in the natural response to wounding of the skin, even though the wound is minute and mainly subcutaneous.
A single needle prick would cause an invisible response.
However, when thousands or tens of thousands of fine pricks are placed together one gets a “field effect”.
This, therefore, promotes the normal post-traumatic release of growth factors and infiltration of fibroblasts.
This reaction is automatic and produces a surge of activity that inevitably leads to fibroblasts being instructed to produce more collagen and elastin.
Benefits of microneedling
Due to the protective function of the skin barrier and the big molecular size of ingredients used in skincare, approximately 99.7% of the applied or sprayed nutritive elements cannot pass through the stratum corner. which is the outmost layer of the skin, but remain on the skin and finally disappear.
Overall, only 0.3%of the applied nutritive elements can infiltrate into the skin.
Therefore, to solve this problem and increase penetration, microneedle rollers are designed to create physical pathways through the skin to increase the permeability and allow the delivery of active ingredients.
