save those sample packets ♡ When you get your samples from Ulta or Sephora, save them! Oftentimes I find that I can get 3 or 5 uses out of a sample packet, and I can throw it away when I'm done which saves just a little more space on the return trip. Generally this is only a good idea if you've tried the product before, because you don't know if you'll get a bad reaction from it and you probably don't want to get said bad reaction on your trip.
transfer products into smaller jars ♡ This has been the hardest for me to master, but I think I've finally done it. Since I'm traveling carry-on only, I kind of have to do this anyway with products that come in big containers. Even so, I've learned to transfer products that contain less than the allowed 3.4oz into smaller containers - it saves a lot of space, especially if you have six other products like that. The past me would have bought my full-size sunscreen and primer with me, but for this upcoming trip I've put them into tiny jars and I'll continue to do that in my upcoming travels!
I bought my small jars here, and I reuse deluxe sample containers when I can. Just remember to label them cause you don't want someone else using your shower gel thinking it's face wash - my mom filled an empty Cetaphil bottle with her shower gel and I used it, thinking it was Cetaphil. Similarly, I filled an empty Josie Maran argan oil bottle with orange essential oil and my sister was thinking about trying it out - which would have been a huge disaster! You could also save the ones you get if you ask for samples... or just ask for samples of your favorite products in-store. Go ahead, I won't judge you ;)
simplify what you bring ♡ Let's be honest here - do I really need to take 3 blushes and 5 lipsticks with me when I'm traveling? No, I do not.
