Fat Transplantation

Method

Skin needling is a procedure that involves using a sterile roller comprised of a series of fine sharp needles to puncture the skin. Performed under local anaesthetic with sedation , the device is “rolled” over the surface affected by acne scars to create many microscopic channels deep into the dermis of the skin, which stimulates your own body to produce new collagen.
