"I am not a big believer in cosmetic treatments. Artificial cosmetic or corrective treatments are damaging. Especially if you see all the studies," Sonam told IANS in an interview.
"I don't judge anybody who does that. It's each to its own and it's all a personal choice. I would rather use products that are safe and the ones that I have control over, not some doctor doing it for me," she added.
In a blog for a website, Sonam recently delved uninhibitedly on the inhibitions and insecurities she harboured through her adolescence "wondering why my body looked nothing like it should". She said that when she embarked on her journey to being a film actress, she also "embarked on a series of unhealthy behaviours," including a diet "that had me eating pineapples all day."
Yet, she smiled through it all.
"There is a risk in being extremely modest. I am always complimented for my smile and that it's my best feature. I also feel that my smile is my best feature," said the actress, who features in a new video for a toothpaste brand.
"I always had nice teeth. I never had braces or cavities. The only issue is that over the years, your teeth start getting stained because of food," said Sonam, who believes that having "beautiful white teeth" is an important part of her beauty regime.
It also helps her to laugh out loud and smile with confidence.
The video featuring Sonam has a song by Arjun Kanungo, and the actress describes it as "sweet and peppy." Of the singer, she said: "Arjun is good, sweet and a great singer. He is also good looking and I am sure young girls are crazy about him."
