She claims she looked like Ugly Betty growing up, but these days Rosie Huntington-Whiteley is considered one of the most beautiful women in Hollywood.

And now the 24-year-old supermodel-turned-actress is sharing her best beauty secrets, including how she cares for those gorgeous full lips.

"I use Lucas' Papaw Ointment religiously, especially when traveling," she told the January issue of Elle. "I also like to use a lip scrub, but when I don't have one, I just rub the edge of my towel to buff away dead skin after I wash my face."

But she avoids enhancing her trademark feature with makeup: "I genuinely don't like a lot of bright color on my lips. They're red anyway, so I keep them really natural," the face of Burberry Body added.

Even if you weren't genetically blessed with lips like Huntington-Whiteley's you should still show them some TLC during the cold, dry winter months.

Glide on a rich balm that has hyaluronic acid to attract moisture. Then, apply a sheer, shimmer-free soft pink or peach gloss. "These shades create the illusion of a plump, moist mouth," celeb makeup artist Nick Barose tells Us Weekly.
