Mayonnaise face masks are believed to tighten skin. Boasting ingredients like egg and soybean oil, Total Beauty notes it's like a natural emollient and helps nourish and calm dry skin. All you need to do spread it onto your face, leave it there for 15 minutes, and then rinse off.

However, there is no proof that this works, as Healthline actually warns against the use of any products containing eggs, and more specifically, egg whites, which is often found in mayo. Though your skin will most likely feel super soft after application, it won't last long, and potential risks include allergic reaction, salmonella infection, skin irritation, and even gastrointestinal discomfort if accidentally swallowed.

If you're looking for a DIY face mask alternative, you're likely to have better luck with a mix of yogurt, honey, and turmeric, or avocado and cucumber (via Elle). Try a few different combinations and see how your skin reacts. You never know, you might whip up a new magical elixir that's yet to be discovered.
