There wouldn't be any difference in firmness. It's still
PMMA whether it's 10% or 30% of the carrier gel. One just grows less collagen because there's less
PMMA in the syringe. I believe 10% spreads out better, less chance of there being too much accumulation in one spot. I'm not sure to what degree it's easier and more efficient for Dr.
Morales to inject and mold 10%.
You wouldn't want to use all 10% and seek the same amount of growth guys usually get from both 30% and 10% in one round. They aren't going to poke you 100 times in order to get 40 syringes of 10% in you and I can imagine a lot of it oozing out because you just can't hold that amount of gel.
However, whether it's
Ellanse or
PMMA, I believe you get more collagen growth per microsphere the less is put in you. This is just my theory but I believe the more microspheres stacked on top of one another, the harder it is for collagen to expand and network together both with itself and with blood vessels. You won't get a proportionate amount of growth in one spot the more product you put there.
Injecting less over multiple rounds has always been known to be better for aesthetics but by how much is unclear. Avanti gets great results with the 30/10 approach. Personally, I wouldn't waste more time and money on travelling to Tijuana for extra rounds if I didn't have to. But if you were really concerned about it and wanted to get half the amount of
PMMA guys usually get in one round I would still get some ccs of 30%. It all depends on entry holes though. You'd have to ask Avanti if doing more ccs of 10% vs having some 30% syringes mixed in with the procedure would cause more entry holes. If they could produce the same result with the same or less amount of entry holes, I personally would choose that route.
