Chest Scar Since Birth, Best Way to Flatten Out? (photo)

Hello Doctors, After a surgery at birth (25 yrs ago) I have had this scar on my chest in between my breasts (closer to my left breast). I have had several Fraxel laser treatments which removed discoloration, but now need advice on which treatments to use on flattening the surface of the scar. Would a dermal filler (i.e. Juvederm) do this? Any opinions would be welcome- I am getting married in 6 months and would like to be worry-free about my v-neck gown! Can send more pictures if needed!
