It is also known as Collagen Induction therapy and works by micro-channelling which stimulates production of collagen and elastin in papillary dermis. A dermaroller creates tiny pricks around the skin giving enough space for wound healing to occur. This in turn leads to a plumper and smoother skin. It targets skin concerns such as acne scars, stretch marks, open pores, facial rejuvenation, hair fall, fine & wrinkles.
