How to treat downward turning ("Katie Holmes") on multi-ethnic Caucasian and Asian hooded eyes? (photos)

Best to see an oculoplastic specialist for in person evaluation. Subtle alterations of eye shape may be okay but not drastic changes. See following link.

changing the shape of your eyes involves too much risk for a very subtle change. I would suggest no surgery whatsoever for what bothers you since the risk of any surgery outweighs the potential gain. 

We usually perform a cheek lift to change the appearance of down-going corners of the eyes.Down-going eyes can be from birth or due to prior lower eyelid surgery performed with a conventional technique.This technique is technically complex so it is best to seek a surgeon with interest in the mid face.

Thank you for your question and pictures! What you have is called an epicanthal fold, and as you noted, it is common in people of asian descent.  As far as the downward turning aspect laterally, well as you also noted, that came from the other side of your family.  There are a couple of minor things that can be done to improve both of these concerns of yours, with minor in-office procedures.  I suggest you find and look for someone who specializes in asian eyelids as that will guarantee your best result.  What you are looking for is certainly achievable with minor tweaking.  Best of luck!

are truly beautiful in my humble opinion but if you must change things, you should see experienced lid surgeons and make sure they can truly provide you with what you desire.  There is no room for errors here as your outcome could be much 'worse' that where you start from.  Unless your consultation or exam truly showed something that could easily be improved, I would suggest waiting until the effects of aging start to impact your lids.
