Actress Ha Ji Won, who is known for having beautifully flawless skin, has unveiled one of her beauty secrets!

The actress recently sat down for an interview with MBC's 'Section TV', alongside cast mates Joo Sang Wook, Kang Ye Won, Go Chang Suk, and Ga In of upcoming film 'The Huntresses' (formerly known as 'The Joseon Beautiful Three Musketeers'), where she confidently opened up.

When asked how she maintains her youthful beauty, Ha Ji Won said she simply washes her face with cold water and has been doing so ever since she was young. "Washing my face with cold water has been a habit ever since I was young. I take cold showers even when the temperature is below 20 degrees," she revealed.

To this, Kang Ye Won remarked, "But she does make sure to wear her long johns during the winter," causing everyone on set to burst into laughter.

'The Huntresses' will hit theaters in Korea later this year.
