Dermaroller therapy or collagen induction therapy (CIT) is a relatively new concept that helps to significantly stimulate collagen to reduce the appearance of acne scarring and wrinkles.The principle of skin needling is to stimulate the body’s own production of collagen. It involves using a sterile roller comprised of a series of fine, sharp needles to puncture the Skin Clinic in Ahmedabad. Performed under local anaesthetic, the device is "rolled" over the surface of the face to create many microscopic channels deep into the dermis of the skin, which stimulate your own body to produce new collagen.
