Can people with sensitive skin or an allergy to metals use the belt? — Universal Belt M 4.3 Ag 140 × 65 mm, 90 × 65 mm, 68 × 65 mm, 77 × 65 mm – Lyapko

According to the card, the needles are made of copper, zinc, iron, silver and nickel. The card has no warnings or contraindications, so it contains no special instructions for sensitive skin or an allergy to metals.

General information (not a manufacturer's instruction): nickel is one of the metals that most often cause contact allergy; if an allergy to nickel or to another metal on the list is confirmed, the applicator should not be used. If skin sensitivity is increased without an established allergy, it is better to consult a specialist first; if itching, rash or marked irritation appear, stop use. Do not use on damaged skin, areas of inflammation, open wounds or in case of dermatitis.
