Skip the SPF
Don’t apply sunscreen or products with SPF if you’re planning on taking flash photography. SPF can cause a white “flashback,” which can make you appear washed out in photos.
Match your foundation
This one seems obvious, but make sure to choose a foundation that matches both your face and neck. If your neck is slightly darker than your face, go with a foundation that matches the darker tone. These shade differences may not be obvious in person, but can show up in flash photography.
Don’t forget to conceal
Flash photography can emphasize dark circles, so don’t forget to apply it under your eyes. Though you may typically use a concealer that is two to three shades lighter than your skin, if you know you’ll be on camera stick with a product that is only one to two shades lighter than your skin tone. You want to find the right balance between brightening your under-eye area, while making sure you don’t look washed out in flash photography. If you’re worried your concealer might be too light, mix in a little foundation with your concealer.
