TOPIC: PMMA Concentration

Hey guys - newbie here. Been lurking for several weeks, trying to gather as much data as I can before taking the plunge. I\'m confident that PMMA is the route to go, but am waffling between doctors. Dr. C seems to be at the top of the leaderboard, but I\'m working internationally for the next year or two, and am much closer to Dr. N in Prague / Seville, who uses 30% x 2 applications, and 10% for touch up as needed at third. I like what I\'ve heard about Dr. C, but have one reservation: It\'s been stated that he uses a 20% concentration of Newplastic. As Mustang2020 astutely observed in the PMMA Complications thread, there is no 20% concentration of Newplastic. He either custom mixes, or uses an \"off-brand\". This is reinforced by the fact that his office is not enthusiastic about showing the actual product - labels, bottles, etc (same thread). That speaks volumes to me. I hope I\'m wrong. The reason for my concern was expertly addressed by coolhandluke - to paraphrase his explanation - mixing concentrations in an office setting will not yield the same accuracy as a concentration mixed at the lab under strict quality control conditions. A \"home brew\" will not be suspended uniformly, and subsequently, will result in an uneven deposition of PMMA particles once the water-based delivery vehicle has been absorbed, resulitng in contour irregularities as collagen forms around the PMMA particles. The point of my rambling is this: with Dr. C\'s focus on 10% primary application, 20% secondary and tertiary, is that considered better than the SA / EU approach of straight 30% for two sessions then 5 or 10% for touch-up? If so, why? I understand the aesthetic goals, but isn\'t that offset by the potential risk if in fact a custom mix is used that could yield untoward results? Sorry for the lengthy epistle. I am astounded by the breadth and depth of knowledge on this board, and am glad to be a participant. Any and all feedback is most welcome. Cheers - HB

I think concentration has far more to do with density and much less to do with volume, so contour shouldn\'t be an issue.

Hello hambone.

Its a toughie deciding which Doctor. Do you go with Dr C who has loads of experience or Dr N in Europe was has done a lot less procedures probably in the range of 30-40 but use higher PMMA concentrations 30% hopefully this will contribute to less procedures and minimise risks.

I hear you also on the 20% NewPlastic concentration used by Dr C its definately a concern but the overwhelming response from those who have had the procedure is that they trust Dr C implicitly perhaps with the exception of CHL still waiting for the Drudge report.

As you say, he either custom mixes, or uses an \"off-brand\" for the 20% concentration. But perhaps has a lab mix it for him.

Hopefully whose concidering having PMMA in Europe with Dr N will receive more information from poineers like eastender. Then hopefully we can make a more balanced decision.

One last thing am sure in his last thread eastender mentioned something about Dr Passy and Europe. If that was to happen then he has the experience to match Dr C.
