Bankson, 19, walked the runway at the Stacey Igel's "Boy Meets Girl" show in New York City Wednesday night, leaving behind years of bullying over the severe acne marking her face.

"I'm a small town girl who sits in her living room and films videos all day and now...I'm in New YorkFashion Week," Bankson told ABC News backstage. "It's still a dream. I am so thankful," she added.

Standing 5ft 11in, the stunning brunette became a YouTube sensation after posting makeup tutorials with her concealing tips on the video sharing site, revealing how she covered her acne-ridden skin before heading out to face the world.

In the videos, Bankson first appears to her 45 million viewers in full makeup. She then strips off the layers of foundation, concealer and powder to reveal a slew of pimples and blemishes.

"I had no idea so many people faced similar problems," she said. "My videos and definitely my 'GMA' appearance allowed me to connect with them."

Bankson solidified her star appeal after she made an appearance on "Good Morning America" back in December 2011 where she revealed to co-anchor Robin Roberts how she had been bullied and tormented and how she dreaded leaving her house.

To avoid the harassment and make good use of her time, Bankson told Roberts that she would stay in, research makeup techniques and even practice on herself.

"I was a total recluse. I didn't want to talk to or see anyone because of my skin," Bankson said. Now, she said those same bullies that tormented her in school and are friending her on Facebook.

According Good Morning America, Bankson says her skin condition is 70 percent improved, but continues to pay regular visits to the dermatologist.

Bankson is in her second year of college and told GMA that her journey has made want to pursue a career in dermatology so she can continue to help others with acne and other skin conditions.

In addition to last night's runway show, she has already shot ads with Bebe and Range Rover, ABC reports. Regardless of her recent success, Bankson told GMA that she is still someone who appreciates inner beauty.

"Models shouldn't be modeling perfection because there is no such thing," she said. "We should be modeling our imperfections."
