Jeisys DENSITY is a radiofrequency platform developed by Jeisys, a South Korean medical device company also known for the Potenza RF microneedling system. Where Potenza delivers energy through microneedles, DENSITY is entirely non-invasive, using a contact tip to deliver RF energy to both deep and superficial layers of the skin without any needles or downtime.

How It Works

DENSITY uses a sequential combination of monopolar and bipolar radiofrequency energy. Monopolar RF reaches deeper tissue layers to stimulate long-term collagen remodeling, while bipolar RF targets the upper dermis for more immediate surface tightening. The device includes real-time impedance calibration, which adjusts energy output based on the skin’s resistance during treatment, helping to ensure consistent and safe energy delivery across different areas and skin types.

Built-in cryogen cooling enhances patient comfort throughout the session, and topical numbing is applied beforehand.

What It Treats

DENSITY is designed for patients experiencing early to moderate skin laxity, crepey skin texture, fine lines, and collagen loss related to aging or weight loss. It is also positioned as a “collagen banking” treatment, a proactive approach to maintaining skin structure before more significant aging changes occur. The device is suitable for both the face and body.

Clinical Data

According to Jeisys, studies using the DENSITY platform demonstrated a 239% increase in newly synthesized collagen, a 76% increase in collagen fiber density, and an 82% increase in elastin fiber density after treatment. These figures are manufacturer-reported and, as with any device, results will vary by patient.
