I do not recommend Perlane for treatment of under eye hollows. It is far too bulky for use in this area. I find that Juvederm Ultra XC and Belotero give the best results when used underneath they eye as they are smooth, lightweight fillers. Hope this helps.
Hi SW. Generally speaking, advanced injectors will reach for a smoother and softer gel than Perlane when injecting under the eyes. Restylane is probably the most common and Juvederm works fairly well also. Perlane and Radiesse or other thicker fillers are generally reserved for the cheeks and lower face. You can see photos at the link below of patients that have been injected with Restylane under the eyes.
