Watch: The Power Of a Good Eyeliner!

Women have long known about the seemingly magical powers of makeup, with mascara able to transform tired eyes and concealer covering up a multitude of sins.

But a South Korean woman's total transformation on camera has revealed just how much cosmetics can really do.

The YouTube video of the unnamed woman's make up removal routine has gone viral with over 2.8 million views since it was uploaded on May 2.

The video, accompanied by cheery music, shows the woman smiling to the camera with a full face of make up before reaching for a cotton pad, shaking a bottle of make-up remover and then partially applying it to her face.

In a few sweeping motions, the woman removes half her make-up, paying special attention to the eye area, before revealing what truly is an eye opening result.

While her bare face shows a less powdery pale and pristine complexion, it is the dramatic difference between her left and right eye that leaves viewers stumped - with the lid of her right eye shrinking noticeably in size.

Despite speculation she may be wearing iris enlarging contacts, the clip shows no sign of her removing lenses in the aftermath, leaving it all down to the beauty of eyeliner.

Now, since the viral success of the clip, there has been a barrage of comments from viewers who are trying to decipher the magic behind the make-up.

Some are saying - 'Where did her eyes disappear to?!' and 'Make-up is magic' to more sympathetic reactions towards women - "Being a woman must be really difficult" and "Yikes! I'm so glad I was born a male. Really!"

But the more pressing question on everyone's lips appears to be: Just what eye products and make-up remover is she actually using?

South Korean's spend about $10 billion on cosmetics each year, with men making up an estimated 10 per cent ($1.5 billion) the of sales according to the Washington Post.
