I'll bring a very emollient balm such as Homeoplasmine or Glossier's Balm Dot Com to relieve dry lips and cuticles, Herben Essentials Lavender wipes to naturally kill germs on my hands without drying them out (these are great for de-germing plane trays, too! ), and a spray to refresh my face on a long flight and set my makeup after—
It's light, doesn't leave white streaks, soaks in immediately, and really protects against the sun's rays.
Glossier's Priming Moisturizer, it's the best new product I've tried in the last two years, I tell everyone about it.
I love Glossier's Balm Dot Com and C.O. Bigelow's Rose Salve.
