How should you start using the belt if you have never used needle applicators before? — Universal Belt M 4.3 Ag 140 × 65 mm, 90 × 65 mm, 68 × 65 mm, 77 × 65 mm – Lyapko

The card does not state the directions for use, the length of sessions, a regimen for getting used to it or any warnings: it describes only the construction of the belt (five movable plates, two adjustable straps), the sizes of the plates, the material and the composition of the needles. Follow the manufacturer's instructions on the packaging.

General information (not a manufacturer's instruction): if you have not used needle applicators before, start with a short session and moderate strap tension to assess the skin's reaction; do not use the belt on damaged, inflamed or irritated skin; do not fall asleep with the applicator on. Slight redness right after a session is possible, but if redness persists or burning, itching or pain appear, stop using it. If you have chronic diseases, are pregnant or are in doubt, consult a specialist.
