Stimcare Period Patches Painful Periods 6 patches are waterproof patches for the abdomen and back that offer a large surface area and can be used for up to 3 days. The patch locally, effectively and quickly relieves the functional discomfort associated with painful periods. It uses eNOsyntex technology, which is based on the principle of oxido-reflection and, like a mirror, reflects the far infrared (IRL) emitted naturally by the body's cells. This concentration of endogenous infrared activates blood microcirculation under the patch to relieve tension associated with painful periods. Placing the patches on the discomfort felt, but also on other clinically identified key points, increases the speed and effectiveness of the action. The patch is water and sweat resistant for 3 days. Made in France. See the explanation inside for all recommended positions for each joint. For better adhesion, apply your patches to healthy, clean, dry skin, especially without moisturizer or sunscreen. The glue is based on natural latex. Do not use if you are allergic to latex or rubber. Store in a dry and temperate place at 10 to 30C. Indication: Painful periods.
