I've heard about these sanitizer mist for a while now and didn't think i really needed it enough to go out and buy it. Fortunately, they sent this product to our office :) . This product is super handy! You just bring it around and when your make up needs a little sanitizing, you just spray it directly on your brush, lipsticks, compact powders to disinfect the product immediately. What is amazing about it is that it works really well on powder products. Usually, your skin's oil leaves a shiny film on the compact powder, whether it's eyeshadows or foundation compact. And once the oil seals in, it makes it really hard to use the product. Spraying this product instantly gets rid of that problem. Usually, i have to resort to kind of scraping the top layer off lightly. I usually bring my makeup bag and small brushes to touch up if needed and these are perfect for on the go! These are a bit pricey, but they are definitely a must have in my make up bag!
