Sloane Stephens recently took to Instagram to share her skin story in partnership with American brand "Vaseline." The petroleum jelly-based products have been a staple for the 28-year-old and she carries memories of the products from childhood.

"Vaseline reminds me of my childhood when my mom would slather my entire body in it, especially my ashy elbows. It helps me tell My Skin Story by keeping me moisturized and glowing….how does Vaseline help your skin speak?" Stephens wrote on Instagram.

For this particular social media campaign/giveaway the 2017 US Open champion wants others to share their own skin stories. For a chance to win Vaseline products, fans can still head over to Stephens' Instagram post and share their "My Skin Speaks" story. The giveaway is set to end on August 6.
