The actress and mom took to Twitter to defend her sunscreen, linking to her website and sharing photos of her two daughters, Honor and Haven, along with Honest's co-founder Christopher Gavigan's kids, Luke, Evie and Poppy.

"As parents, it pains us to hear that anyone has had a negative experience with our Sunscreen. We develop and use Honest Sunscreen to protect our own children – Honor, Haven, Luke, Evie, and Poppy – at the park, in the pool, outside, every day. As with everything we do, we take sun protection seriously here at Honest," the statement says.

"Our previous Sunscreen formulation had a 40-minute water resistance and customers told us that it didn’t apply as easily as they would’ve liked. Based on our own experience and consumer feedback, we redesigned our Sunscreen Lotion for 80-minute water resistance and an improved formulation that allows for easier application and a lighter-weight feel," the statement continues, saying the sunscreen passed "extensive third-party testing in accordance with government regulations" and received the highest score from the Environmental Working Group.
