I have not used it but I have read...can't remember where... so maybe a medical journal...or could have been Ladies Home Journal
that it is not a good idea. The reason they sited is that as we age things begin to move...so the look changes and eyebrows etc may end up not looking so great due to sagging. Well like I said not sure of my source. Just another thought on the topic. Will be interested to hear others responses.
