Olivia Wilde Helps Kick Off Revlon's 'Love Is On' Million Dollar Challenge

Revlon just kicked off its 2nd annual 'Love Is On' Million Dollar Challenge on Wednesday – and the company's global brand ambassador Olivia Wilde is showing her support for the initiative with a special message for fans.

"I am so excited to announce today that Revlon is hosting their second LOVE IS ON Million Dollar Challenge," Wilde, 32, says in a video, shared exclusively with PEOPLE.

"At last year's finale celebration for their first crowd-funding competition, I got to see firsthand the positive impact the challenge had on so many great charities," the actress continues. "This year, Revlon has expanded the challenge to include and help even more women's health causes."

According to Revlon, more than 100 women's health-related charities – including those that help fight breast cancer, cardiac health, neurological disorders, autoimmune diseases, diabetes and more – have signed up to compete in the online fundraising competition, which runs until Oct. 26.

And this year, "the challenge will award large cash prizes," shares Wilde, "including a one million dollar grand prize to the top five charities that raise the most funds over the course of the next six weeks."

The actress is urging her fans to raise awareness for other women. "Help spread the power of love by donating to your favorite charity … and remember to share with friends, family, fans and followers. Love, give, support," says the star.
