Would getting Botox in facial areas where I want to get fat grafting increase the amount of fat that survives?

Botox injections will have no effect on fat injection. Fat is used as a filler; Botox to relax muscles that cause wrinkles. So both can smooth wrinkles in different ways. Fillers are more predictable than fat injection, but fat has the potential to last longer and in general is injected in larger volumes to treat more areas more aggressively. Thanks for your question.

Dear Batavia6074:The molecule of Botox is not known to directly enhance survival of fat grafts. As you point out, in some areas where Botox relaxes wrinkling, there is a synergistic effect with Botox and filler lasting longer together than either one by themselves. This seems to be a mechanical relationship and not a physiologic one. It takes 6-12 weeks to observe how much volume survives from a fat transfer. If there is a large amount of mobility in the area, Botox may enhance survival by reducing a mechanical injury from the overuse of facial expression in that area but this is theoretical at this time without studies. There is a drawback to consider. That is if Botox is used in an area like the cheek, the trade-off will be inability to lift the upper lip, eyelid droop and possibly drooling or food retention in the cheeks from lack of cheek muscle use. This is a very interesting question. Discuss this with your Fat Grafting Specialist!I wish you well.
