Is it Possible for Undereye Restylane to Drop to Frontal Cheek Pad?

It's possible. However, I would follow up with the provider for assessment. Without seeing you in person, it's difficult to know whether or not you had any fat they were working around when injecting the tear trough, or whether you're having some expected swelling.

Without photos, it sounds as if you may be experiencing swelling.. If this is the case, it will improve. As other panel members have mentioned, it is best to wait 10-14 days before deciding how things have "settled."  It is rare for product to migrate, but if it has occurred you can use Vitrase to correct this.

There are several possibilities here:

1. You are still swollen.

2. Filler was put in the wrong place.

3. You are holding more water in association with the treatment than is idea.

The treatment for the first possibility is simply allowing more time for things to settle.  The treatment for items 2 and 3 is adjustment with the enzyme hyaluronidase.
