Does Mac Studio Fix Powder Have Flashback

MAC foundation colour theory is probably one of the most confusing things to understand.

for have pink, blue or red undertones

for yellow – olive undertones

What happened in these photos? The makeup artist didn't suddenly go blind and 'used too much makeup' as the tabloids put it. It's just that they didn't use flashback-proof makeup.
There are certain ingredients in makeup that reflect the light very strongly. This effect is not visible in daylight but is really visible under flash photography.
If you will be in a situation where you will be photographed with flash, you must be sure that you are using photo-friendly makeup. You need to pay attention to your foundation, concealer, illuminating / brightening cosmetics, and all finishing powders.

How to make sure that your makeup won't cause flashback?

The best way to find how your makeup will behave under flash is to test-photograph it. You can apply a strip on your arm in a store and photograph it in a dark place with flash. If the product looks white, it causes flashback. Before a photo shoot, dry doing the makeup and take a few photos with flash -- you might be surprised how different everything looks.
Just because a product has 'HD' or 'studio' written on it, it doesn't mean it won't cause flashback (as Wayne Goss demonstrates in his video). Mineral foundation usually causes flashback, however pure silk powders / bamboo powders which are free from titanium oxide or zinc oxide are safe to use. BB creams contain SPF and often cause flashback.
In Goss' video above he mentions that using a loose pigmented powder on top of your foundation can apparently minimise flashback, so can bronzer.
There are certain ingredients that you need to avoid if you want to buy flashback-proof foundation or powder:

Ingredients that cause flashback:

* Titanium Dioxide (CI77891) and Zinc Oxide (77947)
Makeup that has SPF usually has a lot of titanium or zinc oxide, and will cause flashback. You also need to avoid cream or moisturiser with SPF.
* Silica
Silica can look awesome in photos is really finely ground and used sparingly, it gives a tiny amount of flashback that makes you look glow-y. A good products is the Makeup For Ever HD Setting Powder which looks amazing in photos in tiny doses. The cheaper ELF product is ground much more coarsely, and is easy to overdo.
* Silver Mica
Usually causes a lot of flashback, so it's best to avoid
* Glitter and shimmer
Glitter and sparkle can look very different under strong light. I'd suggest limiting it to the cheeks and eyes. Products with multicolour glitter particles usually photograph better than when the particles have only one colour.

If you are doing an indoor photo shoot, you need to ask before what kind of lighting the photographer will be using. The diffused light from many lamps doesn't cause flashback, but if the photographer plans to rely heavily on flash than you might want to be careful with your choice of makeup.
The up-side to the flashback gaffes of the stars is that you get to see where exactly they apply their highlighting products. I broke this down according to each celeb's face shape in this post.
