What is Dermaroller?
Dermaroller is a hand held equipment with drum-shaped roller studded with fine needles ranging from 0.2mm to 2.5mm in length. Using a dermaroller is also known as micro needling or skin needling.
How Does Dermaroller Work?
During treatment, the dermaroller is rolled over the treated area in multiple directions. Needles pierce the stratum corneum and create pin point holes without damaging the epidermis. The microinjury triggers wound healing and stimulates formation of new collagen, elastin and capillaries. This results in improvement of skin texture and tigtening of skin, thereby significant improving the appearance of stretch marks.
