This effect is from scattering of light through thin eyelid that occurs when an HA filler is placed superficially in the skin. This is rare but possible in darker skin types and can be treated with vitrase. For injections around the eyelids it's best to see an oculoplastic surgeon with extensive experience injecting in this area -- this will minimize the chance of complications and help ensure a natural and long lasting result. The anatomy in this area is delicate and complex but treatment around the eyes, when performed correctly, really provides a "wow" result for the patient because it improves the tired look and can make the entire face appear fresh and relaxed.

The tear trough area is a delicate area to be injected. The Tyndall effect can happen with the injections placed too superficial. The Tyndall effect is less likely with darker skin. For the best cosmetic results please consult a board certified dermatologist with a greet deal of experience with cosmetic injections around the eye area.
The tyndall effect is a light reflex when filler is placed too superficially. If your skin is dark it is unlikely to be apparent, but I use restylane and dilute it before injecting by the lower eye lid to allow for a more malleable product.
Tyndall effect in African American skin
The Tyndall effect is not caused by Restylane as much as it is from superficial Juvederm. It is also much less likely to occur in darker African American skin. Both of these have even less of a chance if you see a great, board-certified injector.
