3–5 days
It is generally recommended to keep ear acupoint patches in place for 3 to 5 days, though the exact duration should be adjusted based on individual constitution, the patch material, and the intended purpose. Standard pressure-type patches typically remain effective for about 3 days, while patches containing magnetic beads or *Vaccaria* seeds can be worn for up to 5 days-provided the acupoints are stimulated via self-massage daily. If skin sensitivity or discomfort occurs, the patches should be removed immediately.
