The safety of REVOFIL has been thoroughly evaluated based on the standards of medical devices and then clinically proven. In our in-vivo test, one hundred seventy-two patients were injected with REVOFIL Ultra(56), REVOFIL Plus(86),REVOFIL Fine(30) and REVOFIL AQUASHINE and AQUASHINEBR were also clinically tested on the suitable standards for those who are aged 20 ~56.
All patients were satisfied after injection with no allergic reactions.
There’s no side effect of REVOFIL reported, the only issue could be from injection technic or the condition of treatment, you might experience some redness or a bit of swelling as being injected but it would be disappeared in a day.  Those reaction could depend on sensitivity of each skin.
