When under eye filler wears off can it cause wrinkles under the eyes ?

Hello and thank you for your question.  No, it doesn't cause more wrinkling after it's worn off, it just goes back to whichever wrinkles you had prior to the injections.

Once under eye filler wears off it will not cause more wrinkles, but your skin will resume the appearance it had prior to the filler injections.  In addition to getting under eye filler injections, using medical grade skin care products and getting regular treatments with platelet rich fibrin injections can stimulate collagen production and help to improve the appearance of under eye skin.  We often see the best results when these combination therapies are used.
