Will filler (restylane) under eye help to reduce lower eyelid retraction? (photo)

Your doctor is correct. Filler injection underneath the eyes can raise the lower eyelids, but the effect depends on the specific anatomy of the person and how much and where the filler is injected. The effect is immediate during the filler injection. The good thing is the filler can be dissolved if needed.

It appears as though you would require minimal product to achieve a natural look. The treatment result and satisfaction is determined by the technique and injector. In addition it is always beneficial to discuss realistic outcomes.  All the Best. 

Lower eyelid injections are really designed to improve the appearance of a deepened tear trough, and must be done carefully to avoid discoloration or creation of "bagginess."  If your concern is related more to lid position, I would recommend avoiding treatment with fillers, as it would be unlikely to accomplish much of a result, and could leave some unwanted side effects.

The tear trough is the area from the mid pupils all the way to the upper medial nasal wall. With age and to some extant genetics, hollowness of the area increases and may look as dark circles. The safest filler in the area is hyaluronic acid. The problem with this material is that the gel may cause a bluish tinge of the lid known as the Tyndall effect. This occurs when light is reflected after a gel is injected in the skin. There are two safe fillers for the area, the FDA approved Belotero, and Teosyal Redensity 2, which is available in most of the rest of the world including Canada. Both these materials do not cause any bluish discoloration after they are injected.No filler should be injected into the eyelid, both upper or lower as the risk of side effects, such as swelling, lumps are quite high in those areas.

I think it would be best to avoid injecting any kind of filler in your lower eyelids.  It will only make you look strange without correcting the problem.  Good luck!

I would advise to you avoid injections into the lower eyelids. I have fixed a lot of these over the years because it can look absolutely bizarre and can also make your blink oddly. Restylane is best used in the tear trough and the upper cheek ridge - not the lower eyelids. "This answer has been solicited without seeing this patient and
