Leniwand, with its advanced non-invasive technology, uses simultaneous cooling and vibration to effectively alleviate pain at the injection site. Capitalizing on the gate control theory of pain, nerve receptors transmit information from vibratory and touch receptors in the skin, inducing an inhibitory effect on pain perception in the brain. This desensitization sets the stage for a pain-free injection experience, complemented by the wand’s cooling feature, which acts as an anti-inflammatory agent, reducing swelling and redness before and after injection.
