To make sure that you bring the products that you need -- and don't overpack -- think about your daily skincare and grooming routine and make a mental note of each product that you use. Pack just those items to avoid bringing products that you really don't need. Don't forget to include tools that you might need, such as cotton balls or cotton swabs. You don't necessarily need to bring every toiletry that you use in your daily routine on your trip. For example, even if you use hairspray everyday to tame your hair for work, you may not need it on a relaxed beach vacation. Cut out any products that aren't necessities. Keep in mind that most hotels provide shampoo, conditioner, and soap, so you may not need to pack those items. The only time you might need to switch up products is if you're visiting an area that's a different climate from where you live. For example, if you're visiting a different hemisphere, the seasons may be different, so you may need a more intense moisturizer for cold, dry weather or plenty of sunscreen for warm, sunny weather. If you're traveling by plane and want to pack your toiletries in your carry-on bag, it's important to consider airport security guidelines in terms of what you can bring and how to pack it. Most airports allows you to bring a quart size (0.95 l) plastic bag with liquids, aerosols, gels, creams, and pastes as long as they're limited to 3.4 ounces (100 ml) per item. Check with the airports that you're traveling through to determine their guidelines to ensure that you pack your toiletries appropriately for security checks. You'll have an easier time packing your toiletries if you have a dedicated bag for them. A bag with compartments is especially convenient because it allows you to organize your products, and prevents spills and leaks from getting all over the inside of the bag.
