Jessica Alba took to Instagram on Tuesday to defend her company from consumers who said her Honest brand sunscreen left their children burned after only a short time outdoors.

The sunscreen controversy has been a public relations nightmare for The Honest Company, with angry moms and other purchasers tweeting, posting pictures of burns that went viral, and complaining on the product's Amazon page. In a note to consumers responding to the accusations, the 34-year-old actress and businesswoman wrote that she and company co-founder Christopher Gavigan use Honest sunscreen to protect their children, mentioning her two girls Honor and Haven.

"Protecting our loved ones and yours is the reason we founded @honest," she wrote. "As parents, it pains us to hear that anyone has had a negative experience with our Sunscreen."

Alba linked to a longer statement on the company's Web site that detailed that the product had gone through "extensive third-party testing" and passed all SPF 30 testing requirements. In addition, the company said, the product received "the best score possible from the Environmental Working Group (EWG)."

Alba and Gavigan said they were reaching out individually to every person who posted on social media: "We want you to know that we hear you and we’re here for you. As always, we’ll do what it takes to make it right."
