Maria Sharapova's marketing skills have been a topic of discussion, and not for a positive reason. But now she has a positive reason to put them to use.

The Russian tennis star is a spokeswoman for a sunscreen product called "Supergoop." The company said her voice helped the company reach millions of consumers, wwd.com reported.

Now, Sharapova is helping Supergoop with a new campaign called Project Black Dot that aims to educate consumers on skin cancer and the benefits of wearing sunscreen daily.

The first part of the campaign, called Project Permission, asks parents to sign permission slips that would allow their children to bring sunscreen to school. According to wwd.com, sunscreen is currently considered an over-the-counter drug and prohibited on school campuses in most states.

"If we can get the awareness that your kid cannot bring sunscreen to school, it's a pretty big statement," Sharapova told WWD. "I think not many parents actually realize that and if you think about that it's quite a shocking fact and we really hope to change that."

Having Sharapova on its side should help Supergoop; Sharapova has been recognized as one of the leading female athlete endorsers in the world. She earned more than $23 million between June, 2014 and June, 2015, according to Forbes, $10 million more than Serena Williams earned as the No. 1 player in the world.

Outrage from Williams supports has grown over the disparity because Williams just missed by two matches of completing the calendar Grand Slam. She owns 21 Grand Slam titles to Sharapova's five, and has a 18-2 lifetime record against Sharapova.
