When you are headed out to a photoshoot, wedding, or party and you know you're undoubtedly going to be taking lots of snapshots (or selfies?), SPF could be your enemy. Why? SPF containing products can sometimes reflect the light of the camera and create a ghostly cast on the face.
Its not to say that all SPF will in fact do this- its just something to know and be aware of. So especially on a wedding day- I say- ditch the SPF for the day and don't take your chances :)
