Some people are leery of anything synthetic. For those who still want a permanent change, there is always the option of using your own body fat as filler. Fat may be taken from another part of your body and injected into the areas that needs filling. You should know however, up to two thirds of it may be absorbed by your body in the three months following. What this means is that it may take several sessions to achieve the look you want. Sometimes fat grafting is used to complement surgery like a facelift or browlift.
