My other most recent can't live without is the Concealing Spot Treatment also from Dermalogica. I need everything that I use to be travel and carry on friendly so check on that front, but more importantly, this works. It is great. I went to my fabulous facialist at Gee Beauty in Toronto (they are great by the by) and spoke to her about my recently horrible skin and she recommended this. her big thing is that not only is this a concealer, but it also is a drying agent and is a healer. Unlike other "spot treatments" that are just dryers, this actually penetrates the skin and promotes healing. A whole bunch of mumble jumble you ask??? Well it works, so I am not judging the pitch. I also like that you can use it 4-5 times a day if you want and not worry about your skin flaking off. It also feels like it works. All good things if you ask me.
As I continue on the purging and pairing down mission, I assume that more things will come out of the wood work as things that I can't live without. These are just the first two.
