The True Form Posture Correcto is designed to help improve posture, but like any product, it may have some side effects. Users often report experiencing slight discomfort in the initial days of use as their body adjusts to the correct posture. This discomfort can manifest as muscle soreness in the back and shoulders.

Some individuals may also experience skin irritation, especially if they wear the device for extended periods. It's essential to ensure that the corrector is fitted properly to minimize any potential skin issues. If irritation persists, removing the device for a period is advisable.

In rare cases, users with pre-existing conditions might experience increased pain or discomfort. It is always recommended to consult with a healthcare professional before starting any new posture correction regimen, especially if there are concerns about underlying health issues.
