✅ How it Works/ Product Description

EMS (Electrical Muscle Stimulation) sends gentle, targeted pulses to your core and pelvic floor muscles.

These pulses mimic natural muscle contractions, reaching deeper layers traditional exercises (like Kegels) can’t.

In just 10–15 minutes per day, the device helps reactivate, retrain, and strengthen the muscles that support your bladder.

It’s non-invasive, comfortable, and clinically backed by muscle rehabilitation research.

Message From Jenny, Our Co-Founder:

"After having my second child and turning 40, I started noticing the little leaks. At first, I brushed it off. But over time, it got worse. I tried Kegels, pills, and pads — nothing fixed it.
As a nurse, I knew this wasn’t just ‘aging’ — it was muscle atrophy. Years of sitting, pregnancies, and neglect had weakened my pelvic core.
I refused to accept diapers as my future. So I looked into EMS — the same technology used in rehab clinics.
After months of testing and refining, I launched this device.
Now, I’m on a mission to help every woman feel confident, strong, and in control — the way we all deserve to."
