After doing some exploration in Paul Ekman's website, I found a link to one of his books, the Facial Action Coding System which has all of the coding information for facial movements. The first two chapters of the book are available online! In the second chapter, Ekman goes over action unit 6 which is the cheek raiser and lid compressor.

I tried doing it and while it seems super easy - it is a bit difficult to control the facial muscles as so.

The end result:
