Estee Lauder Double Wear Concealer - how long does it conceal?

[nicknamenotinuse]

I bought some from ebay last week, put it on my problem blemish and it is off within the hour. I was under the impression this stuff was only removable with a chisel and strong arm?

put it on with a brush and powder over it. It is definitely one of the sturdier concealers. Make sure the blemish is dry first, too.
