Is tyndall effect only due to superficial injection or could it be individual skin?

Thank you of sharing your excellent question.  Tyndall is due to superficial placement of the Juvederm and not necessarily due to your skin.  If your skin is thin there is a higher risk of Tyndall development but this is still due to the filler material.  If you and your injector agree on the Juvederm still being present in your tissues I would continue with hyaluronidase therapy to resolve the discoloration.  Hope this helps.

Tyndall effect is mostly due to the placement of the filler not a patient's skin. Having said that, patients with thin skin are at a higher risk. I'm sorry that you are experiencing this. Best of luck.

Tyndall effect is the way hyaluronic acid react to the ambient light. The thicker the skin the less obvious this effect is. Unfortunately however, in most people when hyaluronic acid is injected in the lower eyelid or the tear trough, the patients wind up having a bag looking collection of fluid (Juvederm) as well as Tyndall effect (bluish hue). Injecting fat over the areas of hollowness of the lower eyelids and Tyndall effect will correct the problem. Good luck from New York City

Thank you for your question.  I'm sorry to hear that you are experiencing complications from your prior Juvederm treatment.  I can't make specific recommendations without assessing you in-person or reviewing your photos.  That said, generally speaking the Tyndall effect occurs when filler is injected too superficially in the skin - the superficial product scatters visible light, resulting in a bluish discoloration.  While the Tyndall effect certainly is more common in fair-skinned individuals with thinner skin, your injector should take this into account when determining which fillers to use and where to place filler injections.  If you and your physician still feel that you are experiencing the Tyndall effect (and are not seeing a superficial vein, or other causes of blue discoloration under the eyes), it would likely be worthwhile to continue hyaluronidase injections - please keep in mind that it can take several treatments to fully dissolve Juvederm.  I hope this helps!
