Have you ever been that person in a picture with a super white face when you know you looked normal in real life? Or, if you haven't been that person I'm sure you've seen that person in a photo...well, you no longer have to look like a ghost in pictures as long as you know a few ingredients to avoid.
When buying foundation, concealer and/or powder look at the ingredients, if the product has titanium dioxide, mica or zinc listed as one of the first ingredients it is time to set that product down and find a new one. Those three ingredients alone or together reflect light and cause you to look white in photos. They are often found in products with sunscreen or used as cheap fillers. If you see one of these ingredients listed at the end of a list of ingredients or it comes after the words "may contain..." you should be fine since they are not the dominant ingredients.
It is only in foundation, powder and concealer that you need to avoid those ingredients. If they are in your eye shadow or blush you are perfectly fine.
So, from now on it should be only your teeth looking white in pictures, not your face!
