Diane Keaton, Eva Longoria, and Aimee Mullins have joined forces with L'Oréal Paris and Melanoma Research Alliance (MRA) to star in public service announcements for their It's THAT Worth It To Me public health campaign.

The initiative aims to inspire women to donate 15 social media seconds to share why it's worth it to protect their skin, beauty and life. As part of the campaign, the celebrities tell their own personal stories of why SPF protection is worth it to drive melanoma and skin cancer awareness, and encourage others to help spread the word. For every social media share, L'Oréal Paris will donate $1 to MRA to fund the L'Oréal Paris - MRA Team Science Award Research Grant.
