Yellowing under the eyes months after eyelid surgery

I had my upper and lower eyelids done in April. All was fine until about 2 months ago when I developed yellowing under both eyes and one small raised area on my right eyelid (which does seem to be resolving itself). Prior to the change in skin color, I had several facials using Pelleve & Derma-Pen during which time the aesthetician treated the eyelids and under eye area with both devices. Could this have drawn fat to the surface of my skin. I don't present as a typical patient with Xanthelasma.
