How Can We Help?

The electrode pads are designed for approximately 15–20 uses.

Actual lifespan may vary depending on skin preparation, body oils, lotions, perspiration, handling, storage, and how well the pads remain in contact with the skin.

Replace a pad if it becomes damaged, dried out, contaminated, or no longer remains flat against the skin.

Apply the pads only to clean, completely dry skin that is free from lotion, oil, cream, and perspiration.

Remove each pad slowly from the edge rather than pulling on the cable. Return it to the protective film immediately after use and store it in a cool, dry place.

When the pads first touch your skin, they may feel cool. Allow approximately 10–30 seconds for your body to adjust.

During use, you may feel mild tingling, gentle pulling, tightening, rhythmic muscle contractions, or see visible muscle movement beneath the skin.

The sensation should be clear and comfortable—not sharp, burning, or painful.

A general routine is two to three sessions per day when used according to the session duration and operating instructions provided with the device.

Space sessions throughout the day and allow your skin time to recover between uses.

Placement depends on the abdominal area you intend to stimulate. Review the Placement Guide before your first session and make sure every pad remains fully on clean, intact skin.

Do not place electrodes on the head, face, front or sides of the neck, across the chest, directly over the heart, or over broken, irritated, numb, infected, or incompletely healed skin.

Do not place electrode pads on or near a fresh, painful, numb, irritated, or incompletely healed incision.

Postpartum healing varies from person to person. Ask a qualified healthcare professional when electrical stimulation may be appropriate for you after a C-section.

YUN MANSION™ Core has not been clinically validated as a treatment for diastasis recti or as a device that closes abdominal separation.

It is designed to stimulate healthy abdominal muscles and support muscle performance. It should not replace medical evaluation, physical therapy, appropriate exercise, or individualized professional care.

Uneven sensation may result from pad position, skin contact, pad condition, cable connection, body position, or natural differences in sensitivity.

Turn the device off, make sure the pads are flat and positioned symmetrically, and check that every connection is secure. Replace pads that are dry, damaged, or no longer adhering properly.
