Sanofi Initiv 3 Neck Patches are patches whose technology optimizes the body's natural ability to relieve acute (short-term) musculoskeletal pain in the neck area.
The patch is coated with mineral particles which reflect the infrared energy emitted by the body towards the painful area to increase blood circulation, improve oxygen consumption and mobility. In this way, it optimizes the body's natural ability to relieve pain for up to 5 days.
It's drug-free, ultra-thin, water-resistant and odorless. It produces no sensory warming or cooling effect, remaining discreet on the skin.
The mineral contains no nanoparticles and does not penetrate the skin.
