I save my most hardcore skincare for long-haul flights when I have to travel for 12 hours or more. They are definitely the priciest items in this list, but trust me: the immediate effects they deliver are worth every single penny. If I am on a red-eye, I apply a generous coat of Aesop’s Sublime Replenishing Night Masque before I fall asleep. It’s packed with Vitamins B, C, E, and F but feels like a lightweight night cream. The formula is nourishing without feeling greasy, and it has a great calming effect on my skin, which gets dry and itchy on a long plane journey. I also like that I don’t have to wash it off when I wake up. I also like to bring the Lucent Facial Concentrate along if I have space in my toiletry bag. It’s a herbaceous Vitamin C serum that can be used as a moisturizer if you’re traveling to a hotter climate, or layered under other skin care if you need an extra hydration boost.
