Penetration of therapy into the dermis and deliver radiofrequency pulse into the targeted tissues. The injections create micro-injuries to the dermis initiate a healing cascade. Injured cells release growth and wound healing signals to undifferentiated cells which results in a localized inflammatory response lasting from one to six hours after the procedure, then fibroblasts are stimulated to produce new collagen. This new collagen fills in the wounded areas, atrophic scars (acne), and thickens the skin. The heat generated by RF produces a healing response that causes collagen production and remodeling, allowing the skin to thicken and adhere closer to the muscular structure of the body.
