What is the Be You Patch? Be You Monthly Patches slowly release a cramp-numbing, intoxicating sensation into your skin over a 12 hour period, to relieve period pains. These 100% natural patches are infused with steam-distilled eucalyptus and peppermint which create a truly unique cooling tingle. They are incredibly thin and so discreet. You can say ‘goodbye’ to bulky hot water bottles! How do I use the Be You Patch? Simply apply the patch to your stomach, during the day or night. They are so slim and discreet that you can wear your normal clothes over them. Be You Patches are registered with the Vegan Society, they are cruelty free, and biodegradable.
