NatPat's Itch Relief Patches contain no chemicals. They work kinesthetically!

Using their Grid-Relief Technology, the Itch Relief patches mechanically lift the skin (no chemicals) to drain the lymphatic system which has been injected by the mosquito's saliva that causes the itch.

Itch Relief Patches will start working in 30-60 seconds to relieve the itch, and can last for up to 7 days (and are completely waterproof)
