Caucasian Eyes to Asian Eyes Possible? (photo)

The muscle responsible for lifting the upper lid allowing us to look above the horizon attaches to the tarsal plate, a cartilage stave stiffening the margin of the lid, and tranversely to the skin of the upper lid creating the TARSAL FOLD which is accentuated and deepened when we look up and goes away when our eyes are closed. The point of muscle attachment to the upper lid is THE difference between western upper lids and Oriental upper lids. The Western upper lid has a higher attachment creasting a tarsal fold while the oriental has a low or missing attachment allowing the upper lid fat to cover its whole surface.

Creating a Western look involves creating a scar attachment between the muscle tendon and the skin at a preset distance from the eyelashes. There are various ways of doing so and it is a VERY popular procedure in affluent Asian countries (such as Taiwan, South Korea, Singapore and even Communist China. 

However, removing the attachment to create a fuller Asian appearing upper lids is very hard because every procedure result is scarring. Removal of the attachments result in scar in the same location worsening the appearance. 

I would suggest you stay away from such procedures.

It is a myth that we can make Asian eyes look Caucasian and vice versa.  On both sides, the goal is to make the eyes more pleasing in shape, with a natural balance to the underlying structure.  If one is seeking a trans-ethnic look, we have to consider a craniofacial reconstruction as well as risking the result that may not "fit" your other features.
