If you have ever thought that Kim Kardashian did not laugh in the picture just for aesthetics you're wrong. The reason is as sad and intelligent as it is.

As he was at the weekend at one of the Master Classes of Mario Dedivanovic, someone asked Kim what was the secret of her skin smooth and untouched by wrinkles.

"Do not laugh," Kim was the only answer.

We remind you that long ago, Kim narrated that "laziness" also affected the negative comments of people during her pregnancy with North West. The 39-year-old told C Magazine that all this influenced the way the Kardashian star wanted to go out in the picture. Likewise added that there was no need to be sweet and smiling to the photographers who shot her photos and sold them.

So from the intention of not appearing the laughing girl on any photo and the desire to avoid any lineage around the lip or eyes, Kim has stopped laughing.
