Being that I am glowing white (practically transparent) the first thing that comes to mind is that I sunburn so I would defiantly need to bring sunscreen! My favorite sunscreen is Neutrogena. They have great spray on version and I love their face sunscreen because it doesn't leave my face all greasy. If I really was on a desert island I would probably get sunburned eventually but at least I could prevent it for a while.
The next thing from my medicine cabinet I would bring would be my favorite face wash from Boscia. It keeps my face clean without drying my skin out and it seems to help my face break out less. I can always use this to wash my body too if necessary so it could be doubly useful.
I think the last thing I would bring would have to be a toothbrush! Not the most exciting choice but if i happened to be stranded on this island with anyone else they would be happy I had my toothbrush.
Come back next month to see what three books I would take if I were stranded on an island.
