oh yes! please mix it with something, water, oil, etc...but not plain...I had accidently got some on my legs when I was soaking my feet (like doing a home foot spa) and I have burn from it as a reminder because of it....
I will probably use some skin whitener to lighten...But do carefully some essential oils can be applied neat (meaning directly on the skin) and some can not and peppermint is one that can not.
