Ecchymosis (bruising)
Ecchymosis is a flat, non-palpable discoloration of the skin that occurs as a result of subcutaneous blood extravasation, and is the most common soft-tissue complication in aesthetic procedures, especially after under-eye filler and periorbital botox, which resolves spontaneously in 10-14 days with the classical five-stage color transition (red-purple-blue-green-yellow).
