TYPICALLY, cause-marketing efforts involve profit-making companies partnering with charities to raise money. But Procter & Gamble, with its seven-year-old My Black Is Beautiful initiative, is introducing a project that is surprisingly ambitious even by the consumer goods giant’s standards.

On Sunday, Procter & Gamble will present a screening of “Imagine a Future” in conjunction with the Tribeca Film Festival. The film, which aims to empower African-American women, features Janet Goldsboro, a teenager from Dover, Del.

“I didn’t look like what I saw in a magazine,” Ms. Goldsboro says about her childhood in the documentary. “I look different from all my cousins. I had dark features, dark hair, dark eyes, big nose and big lips, and I used to get made fun of because of how I looked.”

She says that she is “into boys” — and that their remarks can sting.

“Boys say, ‘I like the light-skinned girls,’ or, ‘I like white girls because I want my baby to come out pretty,’ ” Ms. Goldsboro says. “And that hurts you because it makes you feel like you’re ugly looking.”
