Makeup
Beauty products might be a little expensive, but you tend to get what you pay for. After all, it is hard to determine what dollar store items contain. They might use the same ingredients, but they are probably made with the cheapest version possible. This is the reason prices are so low at the dollar store, after all. Even though the products would probably work just fine, you should avoid them if your skin is sensitive.
Oven Mitt
An oven mitt is used to keep your skin safe from burns when you are cooking. You should avoid buying these things at the dollar store since they are normally made using cheap materials. They would not protect you from the heat! Your hands are priceless, so you should spend more money on oven mitts.
