I live in Florida where the humidity is really bad. I have often found that my makeup basically comes off from the heat and humidity and cannot seem to find anything that will stay in place during the day. I have to say that this product was wonderful. It is easy to apply and feels light which is a big plus. I don not like when makeup feels caked on. The only thing I did not like about the product is that it comes with an applicator, which is basically a large powder puff. After you apply the powder you place it back on top of the powder. It is separated by a plastic sieve for the better part of the word. So when you want to reapply again the powder puff will have excess powder left over from your first application. Having to dusk off the excess you would be wasting powder. So my advice to Dermablend would be to have a switch inside to close the sieve when you place the powder back in.
