in english - it's the puffy pouch that's below your eyes usually when you smile (hence it's also known as the eye smile)
It's a feature that's really favorable in Korean culture. There's been some mixed opinions on them but I personally think it's quite cute :3
A lot of ulzzang's have aegyo sal and/or enhance them with make up.
Do not mistake them for eye bags though. It's easy to confuse the two because they're so close to each other. Eye bags are located at a lower position below aegyol sal (if present).
Even if you don't already have them, a bit of make-up can work wonders ~ Etude House even has a product specifically for this: Dear Girls Cute Eyes Maker.
If you live in North America like me, Etude House products aren't the easiest to come by. However, aegyo sal's aren't really that difficult to recreate. All you need is a medium brown eyeshadow and a pearl highlighter. I like to use nyx's jumbo eye pencils for this.
Because I already have aegyo sal, I skip the brown shadow and go straight to the highlighter. Pink tones tend to make your eyes look "puffy" which in this case is what we want so nyx's strawberry milk is the perfect shade. It's a more subtle effect. If you want a bolder look, use a pearl white highlighter instead.
Ja-jang ~ puffy eye smile!
Just for fun...I ps-ed out my aegyo sal to see how I would look without it since theres a lot of comparison photos like this for Korean celebrities :p
Hmm big difference? y/n?! I still like my puffy eyes more!
Quite a big difference here right?!
Anyway hope you enjoyed this post and the mini tutorial <3
