The beauty secrets behind Miss Universe Thailand's stunning transformation from geek to model

Chalita Suansane won Miss Universe Thailand 2016 and represented her country at the Miss Universe pageant last year.

There is no doubting that the 22-year-old is stunning, but some may be surprised that just over a year ago she was a 'geek' studying microbiology at Mahasarakham University.

Photos have surfaced of her time as a student and have appeared on sites like Elite Daily.

She wore braces, had pale skin and a bit of acne.

Now she is a stunning bronzed beauty queen and model.

Her current life was something she never would have dreamed of if not for her sister applying for Miss Thailand on her behalf.

As to the secret of her transformation, she said:

I never thought I would ever be a model. My sister just joked that we should send in my resume for the Miss Thailand competition. When I applied for Miss Thailand my face didn’t change at all. I just did a lot of exercise and lost some weight. The rest was down to make-up, healthy eating and sunbathing. And a few new dresses.

She lost 15 pounds (6.8 kg) thanks to her fitness regime and new diet.

It all paid off when she came in sixth in Miss Universe 2016.

Surprisingly, the beauty is single and has never had a boyfriend.

She confessed that she has a protective mother and said that she will have one when she is "ready".
