HOW CORE WORKS
Different patterns. Different sensations. One CORE.
A slow, rhythmic stimulation pattern with a gentle tapping sensation.
Alternates between stronger muscle contractions and gentler stimulation, creating a distinct contract-and-relax pattern.
A classic EMS pattern that produces noticeable muscle contractions.
A steady EMS stimulation pattern that creates controlled, consistent muscle contractions.
A faster-paced EMS pattern with a more continuous stimulation feel.
Two TENS stimulation patterns designed for temporary relief of pain associated with sore and aching muscles due to exercise or normal household and work activities.
Low-frequency TENS provides a slower, pulsing sensation. High-frequency TENS provides a faster, more continuous tingling sensation.

FREQUENTLY ASKED QUESTIONS
Clear information to help you understand how Core fits into postpartum care.
Yes. YUN MANSION™ Core is HSA/FSA eligible — you can use pre-tax health dollars at checkout.
It delivers controlled electrical impulses that cause the abdominal muscles to contract. It is designed to stimulate the abdominal muscles and help support muscle performance.
Core has not been clinically validated as a treatment for diastasis recti or other postpartum abdominal conditions. It should not be presented or used as a replacement for medical evaluation, physical therapy, or individualized professional care.
When you first apply the electrode pads, you may notice a cool sensation on your skin. This is normal. Allow your body about 10–30 seconds to adjust before increasing the intensity.
As the device begins working, you may feel gentle pulling, tingling, or rhythmic contractions in your abdominal muscles. You may also notice visible muscle contractions beneath the skin. These sensations are expected and are a normal part of electrical muscle stimulation.
If you experience discomfort, reduce the intensity to a level that feels comfortable.
Postpartum women may use Core for its intended EMS function, but timing after delivery varies. If you have recently given birth or had a C-section or other surgery, talk with your healthcare provider before beginning electrical muscle stimulation. Every recovery is different, so your provider's timeline takes priority over ours.
Do not place electrodes over an incision, irritated skin, or an area that has not fully healed. Ask your healthcare professional when electrical stimulation may be appropriate for you following a C-section.
We generally recommend 2–3 sessions per day. Be sure to follow the recommended session length and instructions in the user guide. Always choose an intensity that feels comfortable for you.
The package includes the Core device, one remote, two abdominal electrode pads, two auxiliary electrode pads, a charging cable, and a user guide. Refer to the product listing for the exact package configuration.
IMPORTANT SAFETY INFORMATION
Always read the complete User Guide before first use.
Stop using the device and consult your healthcare professional if you experience unexpected pain, skin irritation, or other concerning symptoms.
