Too many products, Too little bag.
I myself hate checking luggage. I always try to squeeze everything I own into a carry on so I know my things will never be stolen, broken, etc. The only problem with this is fitting all your beauty needs into a measly little ziplock.
& now is your chance! Pack every little sample you’ve hoarded into that one ziplock meant for your beauty bag. I’m sure you’ll find you’ll have lotions, cleansers, spfs, mascaras, glosses, hair products, etc. that will last you through out your entire trip.
Voila! You’ll get on the plane without exceeding 40 lbs and you’ll fit another pair of heels!
