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 😉
