Is it bad to leave makeup in the cold? Nicole Masson: There’s no reason not to—they will not be harmed by the cold. Anything you can withstand, your makeup can, too. The waxes will get a little firmer though, so lip products will feel a little thicker, almost draggy going on skin.
Is it safe to freeze makeup? Freezing may change the texture of your product, but it’s very unlikely to deactivate the active ingredients. This means after it’s thawed, it might separate, be more difficult to apply, be wetter or go mouldy or off faster.
Can I keep makeup in my car? “Generally speaking, all powders and most liquids are fine in the heat. If the product is visibly separated, try to shake it to mix it back together. If that doesn’t work refrain from using the product as it could potentially affect the skin differently or change the quality of coverage.”
What happens when foundation freezes? Since the frozen area of the ground is much harder than the unfrozen area, it locks the foundation in place. As the ground continues to freeze, the freezing process progresses downwards causing the soil below to lift the top layers. This pulls the foundation up, creating gaps and spaces beneath the foundation.
