Setting powder is one of the most important makeup products you can have in your beauty stash. It’s key to ensuring that your carefully applied beat lasts all day and stays shine-free. The best setting powders are translucent (or slightly yellow) and are finely milled, so they can be easily blended or wiped away from the skin. One of the other things we love about this type of product is that because it has no color, it can be used on any skin tone or undertone without worry.What Causes Makeup Flashback and How Can You Avoid It?The only potential downside of using a setting powder? There’s a little thing called flashback, which happens when you take a picture using flash and a white cast shows up on the areas where your powder was applied. (You’ve definitely seen it on the red carpet, if not in your own selfies.) This is due to the ingredients in translucent powder — namely silica — that reflect the light and create a white cast. Thankfully, there are a few powders out there that are formulated to prevent flashback from occurring.
