- Abstract: Poly-D,L-lactic acid (PDLLA) is widely used in facial rejuvenation as a collagen stimulator, with a lower risk of granuloma formation compared to poly-L-lactic acid (PLLA). However, granulomas may still occur. In this case, a 58-year-old woman developed firm, non-tender, bilateral infraorbital granulomas 2 months after her third PDLLA injection for infraorbital hollowing. The lesions were unresponsive to intralesional trichloroacetic acid (TCA) and intense pulsed light therapy, necessitating surgical removal. Histopathological analysis confirmed foreign-body granulomas caused by the PDLLA filler. This case highlights the need for caution when injecting PDLLA into thin-skinned areas like the infraorbital region, where granulomas can be more visible due to limited tissue volume. Although PDLLA fillers are generally safe, granuloma formation remains a potential complication. Early diagnosis and treatment with non-surgical methods, such as intralesional TCA, should be prioritized. If these methods fail, surgical excision, aimed at preserving as much normal tissue as possible, may be necessary for optimal outcomes.
