Sunnyvale's First XERF Structural Tightening Provider, Marie Jé Aesthetics, Pairs It With Collagen Building

Marie Jin, ACNP-BC, built a different approach to XERF, starting with a collagen phase four to six weeks out, alongside her laser and injectable care in CA.

SUNNYVALE, CA, UNITED STATES, September 11, 2026 /EINPresswire.com/ -- Marie Jé Aesthetics has added XERF structural tightening to its service menu, making the Sunnyvale medical spa the first provider in the city to offer the non-invasive radiofrequency treatment.

XERF delivers multifrequency radiofrequency energy to three layers of the skin at once. It reaches the dermis, where collagen and elastin are produced, the deeper support layer beneath it, and the structural layer below that. Rather than adding anything to the face, the treatment prompts the body to contract the collagen it already has and to build new collagen and elastin over time. Changes tend to show up gradually, usually across two to six months.

What surprises most people is how ordinary the session feels. Integrated cooling protects the surface of the skin throughout, so there are no needles and no numbing. Clients often describe it as a warm, relaxing sensation, closer to a facial than a procedure, and go straight back to their day afterward. Because the energy is radiofrequency rather than light based, XERF is suitable for every skin tone.

The protocol at Marie Jé Aesthetics is where the practice does things its own way. Rather than starting with XERF, the team begins with a collagen building procedure four to six weeks ahead of the first session. The reasoning is straightforward. XERF works with the collagen a person already has, so building that foundation first gives the treatment more to work with and helps the effect hold longer. It is a built in phase of the plan, not an add on.
At Marie Jé Aesthetics, XERF is used along the cheeks and midface, the jawline, under the chin, and the neck. Most clients complete a short series of sessions and return periodically for maintenance. Founder Marie Jin, ACNP-BC, a board certified acute care nurse practitioner, assesses each person's skin and builds a
plan before any treatment begins.

"People come in expecting something intense, and then they are a little confused about how relaxed they feel," said Jin. "That comfort is the whole reason I wanted this device. Pairing it with collagen building first is what makes the result last, and that is the part I care about."

XERF joins a menu that already covers a wide range of concerns. The practice offers laser treatments including PicoWay, Aerolase, and its Tight and Bright Laser Facial, along with laser care for acne, scarring, and unwanted hair. On the injectable side there is Radiesse facial contouring, lip contouring, wrinkle treatment, and fat reduction injections. Regenerative options include PRF gel and skin boosters such as Skinvive.

The through line is a Korean approach to aesthetics that favors gradual, natural looking change with an emphasis on regenerative care. The team builds plans around what each person actually wants, whether that is a firmer line along the jaw, more even tone, restored definition in the cheeks, or a routine that simply keeps things steady over the years.

That range is deliberate. Aesthetic goals look different at 30 than at 55, and different again depending on skin type, budget, and how much time someone has. The practice was built to meet people wherever they happen to be, with consultations that start by listening.
Marie Jé Aesthetics is located at 468 E El Camino Real in Sunnyvale, in the heart of Silicon Valley and the South Bay, serving Santa Clara, San Jose, Cupertino, and Mountain View. Consultations can be booked online or by text at (408) 800-6938.
