I've tried the old of Estee Lauder white light products before. I think it's only to protect your skin from sun damage. It's Perfect for summer though. I wasn't intended to buy their stuff before, but they dragged me off, and I had problems to say "no thanks" to people before. So I just purchased the product and it's over lol.
I still have it though, I don't really use a lot. Wasted my money, when I think of that now.
You should try their sample first, before you buy their stuff.
Ask for the samples of the products you want to try, I'm sure they will give you.
