7. Body Lotion. It would be nice to just slather on one lotion and be done with it, but body lotions should NEVER be applied to your face because they're usually a lot thicker and typically contain fragrances that might irritate your facial skin. On your face, you should always use something more gentle and delicate. Think of body lotions and creams like spackle — they're there to fill in lost moisture, not to target your facial needs like anti-aging.
8. Foot Creams. This is basically a no-brainer, but if you're desperate and only have a foot cream laying around, DO NOT put it anywhere near your face — even if you just have a tiny dry patch. They're just too rich, thick, and sticky to be applied to your facial skin. They're formulated to break down thick calluses on your feet and often contain chemical exfoliants at percentages that you would never want to use on your face.
9. Nail Polish. Trying to paint your face for a Halloween or costume party? This only belongs on your nails. It has acrylic molecules that will actually dry the skin out. So, if you're thinking about doing up your face for a theme party, only use paint designed for your face.
10. Acetic Acids aka Vinegar. Yes, you can apply vinegar onto your face as a toner, but it's better to get a toner that contains the ingredient instead of whipping a bottle out of your kitchen cabinet. Vinegar can lose water over time and become stronger, so if you use it on your skin, it can actually burn it if you don't know exactly how long it's been in your possession.
11. Mayonnaise. This ingredient is in a lot of DIY hair masks because it's hydrating TO YOUR HAIR. But it's not a good idea to put it on your skin because it's too acidic and too occlusive, meaning it doesn't allow your skin to breathe and can clog your pores. If you want to try any at-home facial masks, here are a few that are safe to whip up.
