I have to say that there were three products that were AMAZING to use.
1. Mineral foundation by TLC Mineral Makeup. No talc in the product. It gives good coverage with a stiff foundation kabuki brush and has a flawless finish when the skin is prepped with a primer. I used Lise Watier Base Miracle Pore Reducing Primer. So I guess that's two products right there.
2. Urban Decay Primer Potion. Your eyeshadow will not move at all, not even the eyeliner, with this as a base. The Tawny Matte version also gives a nice canvas to work on, covering any redness or darkness on the eyelid.
3. Make Up For Ever Mist and Fix. I spritzed this on each of the girls, including the ones that did their own makeup and it kept their faces looking just-made-up all day, even in the hot sun (98 degrees that day) where they stood, without shade, for an hour through the ceremony and another two hours getting photos done. I went with an on-set bag ready to do touch-ups and all that was needed was lip gloss for my two girls and a bit of under-eye liner for my daughter from crying during the ceremony. Other than that, not a single touch-up needed in over ten hours. Amazing. I will never be without this product in my kit.
In fact, I won't ever be without any of these four products in my kit.
