her acceptance speech at the oscars was just a model of a speech and that's not the only speech she's given and spoke at a Hollywood luncheon earlier and gave an inspirational message about beauty and skin color that struck a chord with millions of women. ABC's Deborah Roberts has the story. Reporter: Lupita nyong'o, fashion icon and now Hollywood golden girl. When I look down at this golden statue may it remind me and every little child that no matter where you're from, your dreams are valid. Reporter: Her stirring words at the oscars warmed hearts. But it's Lupita's other emotional speech made days before that struck a nerve. At "Essence" magazine's black women in Hollywood luncheon she fessed up to a private pain. Dear Lupita, it reads. I think you're really lucky to be this black but yet this successful in Hollywood overnight. Reporter: Through tears Lupita revealed a haunting secret about her dark skin. I remember a time when I too felt unbeautiful. I put on the TV and only saw pale skin. I got teased and taunted about my night shaded skin and my one prayer to god, the miracle worker, was that I would wake up lighter skinned. Reporter: Posted over the weekend her gripping speech has gone wildly viral climbing to nearly 2 million views. At that moment tell me, you were right there. What did it feel like? How did people react? I saw tears. There were tears. People were spellbound. Reporter: The 31-year-old Kenyan beauty revealed a bitter truth that black women know too well. That mainstream beauty standards don't always include them. In the crowd visibly speechless and proud, Regina king, Angela Bassett and Oprah Winfrey. Online a barrage of comment, Lupita is the truth said one viewer. I love this so much I just want every young girl to hear it and know it and live it said another. But for some, her statement wasn't just about race, but about beauty in us all. A lot of women have this very unrealistic standard of beauty that is so narrow and so far removed. Beauty was not a thing that I could acquire or consume. It was something that I just had to be. Reporter: What a woman. Lupita's deeply personal story has had a ripple effect worldwide with a tapestry of women from all backgrounds finding the courage to admit and begin conquering their insecurities but for women of color especially dark skinned women like myself it's an opportunity for healing old wounds. I permanently understand Lupita's journey growing up as a sad and sometimes unhappy young woman myself because of the color of my chocolate skin. Those feelings of worthlessness and inadequacy can run deep and leave scars. It's an open secret, of course, among black women, one that you mentioned, robin. People talk about it but hopefully with talking about it -- The emotion -- it's getting to you. I heard from so many of my friends yesterday. They had seen this. At the luncheon prior to the oscars and were aware. I tell you what, beautiful then and now. Thank you but she touched on something that we all need to do a little better about, talking about it and healing. Right. All right. You're getting me all weepy.
