Haha I was thinking the same thing! I am SO ready for it to be summer!
As for what my fav summer moisturizer is, it doesn't change from my winter one. It will always and forever be DDF Photo Mat sunscreen SPF 30. The mattifying effects aren't needed that much in the winter, but in the summer I bet they'll really come in handy. I have another sunscreen in SPF 45 that I'll use the days I'm outside longer, but 99% of the time I'll be using the DDF.
