Advances in the processing of materials on a micro-scale have led to the development and introduction of devices that employ very small needles – disk-needles – that deliver drugs or cosmetics by mechanically perforating the out skin layer and allowing for transdermal absorption of the active compound.
It is a therapy that stimulates wound healing process to produce new collagen and elastin and therefore, reduces the appearance of fine lines, wrinkles, scars, and stretch mark. This technique is also applied to improve skin texture and tighten pores. By introducing active ingredients into the deep skin tissue at higher absorption rate, skin needling is applied to treat hyper-pigmentation (brown spots), active acne skin and alopecia as well.
