03 · HOW IT WORKS
How the Core Device
Activates the Muscles.
The Core device sends controlled electrical impulses through the electrode pads to the abdominal muscles.
These impulses create repeated muscle contractions during each session.
Electrical Impulses
The controller sends adjustable electrical impulses through the connected electrode pads.
Muscle Contractions
The impulses cause the abdominal muscles to contract and release in a controlled rhythm.
Repeated Activation
Each session provides repeated stimulation of the abdominal muscles.
Everyday Routine
The wearable design makes it easier to include muscle stimulation in everyday postpartum care.
IN SIMPLE TERMS
The electrical impulses act as a signal that encourages the abdominal muscles to contract and release. The intensity is adjustable, allowing you to begin gently and select a level that feels comfortable.
Regular sessions are intended to make abdominal muscle activation easier to incorporate into your postpartum routine.
Electrical impulses.
Muscle contractions.
A consistent routine.
INTENDED ROLE
The Core device is intended to stimulate healthy muscles and support muscle performance. It has not been clinically validated as a treatment for diastasis recti or other postpartum abdominal conditions.
04 · GETTING STARTED
Prepare the Device.
Prepare Yourself.
Complete these steps before placing the electrode pads on your body.
Do not turn on the device until the pads are connected and positioned correctly.
Charge
Charge the controller and remote before first use. Do not use the device while it is charging.
Connect
Connect the electrode pads securely to the controller before placing them on the body.
Prepare Your Skin
Clean and dry the treatment area. Remove oils, lotions, creams, and excessive hair if needed.
Power On
After the pads are correctly positioned, turn on the controller and remote. Begin at the lowest intensity.
BEFORE POWERING ON
Make sure the electrode pads are fully connected and placed flat against the skin before turning on the device.
Do not apply, remove, or reposition the pads while stimulation is active.
05 · PLACEMENT GUIDE
Placement Changes
Where You Feel It.
Electrode placement influences where the stimulation and muscle contractions are most noticeable.
Begin with the recommended centered placement. Alternative placements should be used only when shown in this guide and supported by the final product instructions.
01
Centered Abdominal Placement
Position the abdominal pad horizontally across the central abdominal muscle area. Keep the pad centered and flat against the skin.
WHAT YOU MAY NOTICE
Stimulation may feel most noticeable through the central abdominal muscles, with relatively balanced sensation on both sides.
This is the recommended starting placement.
02
Lower Abdominal Placement
Position the abdominal pad slightly lower on the abdominal muscle area while remaining above the pubic region and away from any incision.
WHAT YOU MAY NOTICE
The stimulation may feel more noticeable through the lower abdominal area than with centered placement.
Do not place over a C-section incision unless it is fully healed and a healthcare professional has cleared use.
03
Central + Lateral Placement
Keep the abdominal pad centered and place the two auxiliary pads symmetrically over the left and right lateral abdominal muscle areas.
WHAT YOU MAY NOTICE
You may notice stimulation through both the central and lateral abdominal wall.
Use this arrangement only if it is expressly supported by the final product instructions.
PLACEMENT PRINCIPLES
Stay symmetrical
When using paired pads, place the left and right pads in comparable positions.
Place over muscle
Apply pads flat against intact abdominal muscle tissue—not over bone or an incision.
Keep pads separated
Do not allow electrode pads or conductive gel surfaces to overlap.
Reposition only when off
Turn stimulation off completely before moving or removing any electrode pad.
DO NOT PLACE ELECTRODES
Areas to Avoid
On the front or sides of the neck
On the head, face, eyes, or across the brain
Across the chest or in a path that sends current through the chest
Directly over the heart
Over the spine or prominent bones
Over open wounds, rashes, infected, swollen, or inflamed skin
Over numb skin or areas with reduced sensation
Over a fresh or incompletely healed C-section incision
Over known or suspected cancerous lesions
Over metal implants unless cleared by a healthcare professional
Over areas where medication is delivered through the skin
Across the lower abdomen during pregnancy
Do not create an electrode pathway across the chest, head, neck, or other prohibited areas. Ask a qualified healthcare professional before use if you have reduced sensation, a recent surgical procedure, or uncertainty about electrode placement.
06 · YOUR FIRST SESSION
Your First Session.
Start Slowly.
Your first session is an opportunity to become familiar with how the Core device feels.
Begin at the lowest intensity and increase gradually. The goal is a clear, comfortable muscle contraction—not the strongest possible sensation.
Begin at the Lowest Intensity
Turn on the Core device and begin at the lowest available intensity.
Allow approximately 10–30 seconds for your body to become familiar with the sensation.
Increase Gradually
Increase the intensity one level at a time until you notice a clear, comfortable abdominal muscle contraction.
The sensation should not feel sharp or painful.
Relax and Breathe
Remain in a comfortable position and breathe normally throughout the session.
Do not actively brace or hold your breath unless instructed by a qualified healthcare professional.
Finish Safely
When the session ends, reduce the intensity to zero and turn the device off.
Remove the electrode pads slowly and gently from the skin.
WHAT YOU MAY FEEL
New Sensations Are Expected.
Sensations vary by placement, intensity, skin condition, and individual sensitivity.
A cool sensation when the electrode pads first touch the skin.
Mild tingling as stimulation begins.
A gentle pulling or tightening sensation.
Rhythmic abdominal muscle contractions.
Visible movement of the abdominal muscles beneath the skin.
Allow approximately 10–30 seconds for your body to adjust before increasing the intensity. If the sensation feels uncomfortable, reduce the intensity.
STOP THE SESSION
Stop if Something Does Not Feel Right.
Sharp or increasing pain
Dizziness or feeling faint
Significant burning, itching, or skin irritation
Any unusual or concerning discomfort
Reduce the intensity to zero and turn the device off before removing the electrode pads.
If symptoms continue after the session has stopped, discontinue use and consult a qualified healthcare professional.
A higher intensity is not always better.
Comfortable, consistent use matters more.
07 · RECOMMENDED ROUTINE
Build a Routine
That Feels Sustainable.
For most users, YUN MANSION™ Core may be used for two to three sessions per day when used according to the session length and instructions provided with the device.
Choose a routine that feels comfortable and realistic for your body and daily life.
GENERAL ROUTINE
2–3
Sessions Per Day
Space sessions throughout the day rather than completing them back-to-back.
Always follow the recommended session duration shown in the final product instructions.
CHOOSE COMFORT
Clear Contractions.
Comfortable Sensation.
Select an intensity that creates a noticeable abdominal muscle contraction without sharpness, burning, or pain.
You do not need to use the highest intensity to complete an effective session.
Space Out Your Sessions
Allow time between sessions instead of completing several sessions consecutively.
Choose a Comfortable Intensity
A clear muscle contraction should not require sharpness, burning, or pain.
Focus on Consistency
A manageable routine is more useful than occasionally using an intensity that feels excessive.
Give Your Skin Time
Wait before another session if the skin beneath the pads feels irritated, tender, or unusually sensitive.
EXAMPLE SCHEDULE
A Routine That Fits Your Day.
This is one example only. Your schedule may look different depending on your comfort, recovery, and daily routine.
Morning
Begin with a comfortable session after your morning routine.
Afternoon
Allow time between sessions and check how your skin feels.
Evening — Optional
Complete a third session only if your skin and body feel comfortable.
LISTEN TO YOUR BODY
Do not use the device on irritated, sore, or damaged skin. If the electrode area remains red, tender, itchy, or uncomfortable, wait until the skin returns to normal before another session.
Do not double your sessions to make up for a missed day.
Consistency does not mean perfection.
Choose a routine you can use comfortably.
08 · CLEANING & STORAGE
Care for the Device.
Protect the Pads.
Proper cleaning and storage help protect the device, support reliable adhesion, and keep each session more comfortable.
