Maria Sharapova four-time tennis Grand Slam champion, joined sunscreen maker Supergoop! as an equity owner.

The partnership is a foray into the beauty product category for Sharapova, who sees her latest venture with Supergoop, which was founded in 2007, as an opportunity to educate people about the dangers of skin cancer.

Supergoop focuses on sun protection at the core of its anti-aging skincare products, which Sharapova said she’s used for several years while playing in tournaments and spending long hours practicing in the sun in her home state of Florida.
