Potenza Microneedling SystemSpecialist

New Image Medical Spa

Surinder Sandhu, MD

Medical Spa located in Fremont, CA

The Potenza™ RF microneedling system can help to address the most common aesthetic concerns because of the benefit of advanced radiofrequency technology. Potenza delivers thermal energy to deeper tissue, causing tissue contraction. The energy/heat also triggers the body to produce collagen and elastin, resulting in skin tightening through soft-tissue coagulation. With this effective treatment, Surinder Sandhu, MD, helps patients at New Image Medical Spa get their best skin.

The Potenza™ RF microneedling System


What Is Potenza Microneedling System?

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 soft tissue 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.

Intended Use of the Potenza

The Potenza radiofrequency system is intended for use in dermatologic procedures for electrocoagulation and hemostasis.

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
