About Potenza™

The Potenza™ RF microneedling system adds the element of radiofrequency energy to the traditional microneedling procedure. The RF energy is delivered via small needles. In addition to the benefits seen with the micro-injury provided by the microneedles, RF microneedling also delivers RF energy deep into the dermis, further enhancing skin tightening through soft-tissue coagulation. The RF energy heats the underlying layers, causing constriction and tightening of the skin through softtissue coagulation, as well as causing the stimulation of collagen and elastin production. Because the RF energy is delivered so deeply, it can produce faster, more dramatic results.

What is Radio Frequency (RF)?

Radio Frequency (RF) is part of the electromagnetic spectrum characterized by a specific frequency measurable in Hertz (Hz).

RF energy produces a change in the electrical charges of the treated skin creating an electron movement. The resistance (impedance) of the tissue to that electron movement generates heat.

The amount of heat generated depends on these factors:
• Impedance of the treated skin
• Intensity of the current applied
• Length of time of exposure to the RF energy

How RF Works

Collagen is remodeled and Elastin is improved through the wound healing response.

  1. Heat is applied to the epidermis creating an Inflammatory Phase (1-3 days)
    a. Early contraction of blood vessels (5-10 minutes)
    b. Vasodilation in order to increase blood supply (multiple hours to 1-3 days)
    c. Cells (macrophages, neutrophils, etc) infiltrate the damaged area to
    remove dead/damaged tissue and destroy bacteria.
  2. Proliferative Phase – 3 weeks
    Ongoing Process to repair tissue
    a. Day 2-3 – Fibroblast activity is induced in damaged tissue. Fibroblasts multiply,
    send mediators to stimulate repair, combining with damaged tissue
    b. Day 5-7 – Fibroblasts begin synthesis of collagen. (Day 7-21)
    c. Day 7-21 – Old collagen is removed by collagenase
  3. Maturation Phase – 3 weeks to 6 months and beyond
    a. New collagen is generated
    b. Elastin becomes more uniform and the quality is improved
