Dear harley100,Hello and thank you for your question. I assume that you have had some loss of volume and skin laxity as a result of overfilling the troughs, and then treating the area with hyaluronidase to disintegrate the filler. There are several treatments that can help tighten and rejuvenate the under eye area such as fibroblast plasma pen, which uses a pen like device that discharges and releases a targeted current right above the skin. This creates small micro-injuries on the skin’s surface, which help to tighten the skin, stimulates collagen as well as improve overall texture. You can also treat the area with microneedling paired with radiofrequency, to tighten the skin and stimulate collagen production. A suitable, medical-grade skincare regimen is highly recommended and daily use of SPF. Best of luck.
