Skip the bag- Keep the lotions!
The lotions are amazing and have been using for about ten yrs. If you want a tan and not peeling use these. HOWEVER, this order i decided to get the bag for easier carrying and these bottles don’t fit.. kinda ridiculous

You don’t look like Casper the ghost!
Color: 25 Sun Protection Factor (SPF)
A really nice clean sunscreen a little goes a long way. I just used it on my face and love the fact that it didn’t turn it completely white. It’s quite sheer protective and hydrating.
