Step 1: Remember 3-1-1
Airport regulations allow "3-1-1" rule for carry-on bags: 3 ounce bottles or less; 1 quart-sized, clear, plastic, zip-top bag to hold the bottles; 1 bag per passenger placed in the security bin. If you have larger bottles of liquid, you must put them in your checked baggage.
Step 2: Consider your destination
Are you headed to a tropical locale? Select products that can withstand the heat and humidity. You can probably do without the heavy foundation and rich creams. If you're attending any parties or formal events on the trip, be sure to bring your evening makeup -- darker eye and lip shades with a bit of shimmer.
Step 3: Use 2-in-1 products
To conserve space, use as many 2-in-1 (or 3-in-1) products as you can. With many mineral powders and other cosmetics, you can use one product for eyes, lips and cheeks. For bath and body, consider a shower gel that also doubles as shampoo. Or just forgo the hair care products and use those supplied by your hotel.
Step 4: Take advantage of samples
The makeup counter at your local department store will readily handout free or very low-cost sample or trial sizes of cosmetics. These are perfect for traveling on short trips. The small containers will take up very little space in your bag.
Step 5: Slip it in your shoes
For breakable bottles of perfume and other makeup, place the containers inside socks and then put the socks inside your shoes in your suitcase. Many people overlook the extra space inside shoes when packing.
Step 6: Consider a traincase
If you have a lot of makeup that you really want to take, buy a cute metal traincase to hold all your essentials. Make a checklist that includes foundation, concealer, powder, eye shadow palette, mascara, eyeliner, blush and two lip colors.
