On the beach in Greece once, I used a lip balm that I had just received in a party swag bag. It was cloudy and cold, I was out there just a couple hours--but, by the next day, my lips had turned into two big blisters. The balm had mucho oil and zero SPF in it. Now, I tell everyone to wear lipstick with SPF when on the beach. Bare Escentuals’ mini-lip gloss set is GREAT for travel: you get 6 sun-inspired colors, all travel size, all with hydrating aloe vera and shea butter, plus nourishing vitamins A, C, and E, and SPF 15--all for just $36.
