Keeping lipstick in the fridge is a good idea. Use PLASTIC WRAP on each lipstick, then put in a zip lock bag.
If you go to Este Lauder they will do it for free, the woman that did mine said that you don't have to buy a product unless she uses something you like.
They have a light diffusing concealer that I didn't like. It looked dry. Este lauder has one that has a built in brush that works much better. It's like a large pen.
