Avoiding Ghost-face in photos

It's party season! And about time too. I cannot wait until Summer with some awesome cocktails and lots of chances to catch up with people that I have missed over the year. But what also comes out when you gather a group of close friends and family? Cameras.
Has anyone else ever had that annoying look in your photos where your face is paler then your body and you can't put your finger on why? It happens more at night then during the day. Guess what it is? SPF in your make-up and moisturiser.
This is because the SPF ingredients reflect the light of the flash and make you appear ghostly pale. So next time, make sure you use products that do not contain SPF, and your pictures won't come out so odd, (It's not like you need it when the sun goes down anyway!)
