Eye shadow palettes are pretty delicate and could break while traveling. As a result, avoid traveling with large palettes. Instead, go for quads or trios.
You can also add cotton pads on top of the eyeshadow, trim them to fit properly, and shut the lid carefully. This will hold everything together.
Avoid bringing too many liquid goods, and secure those you absolutely must have with scotch tape.
Two to three pieces of tape should be used to seal the top of your products. To prevent spilling, ensure that the tape completely covers the cap.
Instead of risking the ruin of your favorite makeup, carry only those that may be used for multiple purposes.
Some liquid lipsticks, for example, can be used as blush and eyeshadow to create a monochrome effect. Invest in things like these and make good use of them while on vacation.
To avoid shock and spills, place your makeup bag in the center of your baggage.
Wrap the bag in a sweatshirt or towel before placing it in the suitcase to make it even more secure. Wrap a pair of socks over fragile things with glass packaging, such as fragrances.
Another wise move is to repackage your products in smaller packaging. Reusable plastic bottles are widely available and will keep your products from spoiling.
Pack products that you use seldom, such as concealer or primer, in old contact lens containers.
