A month ago I broke out with cysts all over my chin so my derm injected them with cortisone. Now I have 2 small and 1 very large hollow areas in my face. Should I use temporary injectable fillers like restalyne, juvaderm, etc? Will they inhibit the regrowth of collagen in the spots or do anything else bad to them? The length of time they last seems perfect bc the collagen should reform in ~6 mos. Which one is best to use for this? Should my dermatologist or a plastic surgeon do this? thanks!
