I got under-eye filler about 4 months ago and I feel it’s made my under-eye wrinkles worse. (Photo)

Hello, you do have some lower eyelid wrinkling that accentuates in animation, from your above photograph. I think the filler may need to be injected at the bone level instead of the dermal layer within the skin to help elevate the skin away from the orbital rim. Alternatively, laser tightening will provide some smoothing of skin, however, some lasers can cause hyperpigmentation in pigmented skin. I would also consider a chemical peel to provide some smoothing of the skin surface. 

Since your filler is most likely partially breaking down already, it may not be necessary to inject anything to break it down. It would be more helpful to see before and after photos with a straight face and smiling before recommending anything more specific about your filler. Based on the wrinkling you have on animation, micro Botox in the lower eyelid muscles (2-4 units spread out over the lower eyelid) could help smooth things out. I don’t think CO2 laser is a bad idea, but I recommend going to a practitioner who is experienced in treating patients with darker skin. 

If you're unhappy with your final results, you can have it reversed with hyaluronidase and try a different technique next time. Keep in mind, a combination approach will give the most improvement. Fillers, lasers, and microneedling/PRP can improve under the eyes. My patients try to get non surgical treatments to avoid surgery. We use PRP and stem cells there often. I suggest consulting with an expert to develop a treatment plan best suited for your short and long term goals. Best, Dr. Emer
