collagen induction therapy reviews Collagen Induction Therapy – A term coined by Dr. Mathias Aust based on the combined work of Drs. Orentreich, Fernades, Camirand, and Doucet. Collagen Induction Therapy describes the process by which the skin is punctured by needles causing the induction of new collagen formation. The natural posttraumatic inflammatory cascade is stimulated by thousands of controlled microwounds in the dermis. These wounds cause a superficial inflammation which ultimately results in an increase in dermal collagen.
