How much caution do you think should be used...what concerns did you have, if any? Happen to have any write up or article that helped you try this? Very cool
You need to be very careful with this stuff
and only do one spot on your face at a time.
I would also do a couple spots some were besides your face to start.
I have only used it 3 times so far..
good luck and BE CAREFUL WITH THIS STUFF!!!
