I keep Lavender in the kitchen to help my poor arms when I am cooking.  I tend to knick my wrists of get my fingers to close to hot areas.  So I apply to the affected area immediately after I lose the battle to the oven rack.  Reapply every 15 minutes.

Personally I have never had to reapply more than twice.

Have a Happy Day!  Keep the Lavender on hand in the kitchen if you will be cooking today 😉
