Fat Grafting vs. HA Fillers: Recorded Webinar + Q&A

In our recent webinar, we took a comprehensive exploration into understanding the difference between choosing HA Fillers or Fat Grafting for gluteal augmentation procedures, how to select the right patient for each one, and the impact of rheology when choosing a product for BioScience’s portfolio. 

In case you weren't able to join us for the live session, the entire webinar has been recorded, allowing you the flexibility to catch up at your convenience. Moreover, all the insightful queries posed during the session have been thoughtfully addressed by our panel of experts, and you can find these responses detailed below.

Q1 Which is safer, filler injection or fat injection?

Dr.Kotti: The safest procedure is the technique that you master, which means that it is possible to have an accident with both procedures. However, embolism and/or death can be related directly to  BBL, and these situations are not common with  HA fillers. That’s why, for me it is better to master the technique of lipofilling or hyaluronic acid to avoid possible complications.

Dr. Schaludraff: There is an advantage in terms of the safety of doing the HA injection, even though I’m a big proponent of fat injection to the buttocks. This advantage is that is easier to know where anatomically you are during the procedure. During the injection of HA usually when you get close to the deep fascia and by mistake you have entered the muscle in a setting of local anesthesia, the patient will react. This won’t happen with a patient under general anesthesia.

Q2: Asking about hyaluronidase, how many units do we need to resolve 10 ml HYAcorp?

Dr. Schaludraff: I think, ultimately, there aren’t systematic studies on what is the exact dosage, but there are also many factors such as how much fibrosis, how much it is encapsulated, how precise are the hyaluronidase injection. As Dr. Frank mentioned, we need to take from the face experience in terms of dissolving HA and then translate it to body procedures to have approximately the same protocol. I do believe that ultrasound-assisted hyaluronidase injection is key because you target the enzymes, and I think this is the way to reduce the enzymes used.

Q3: How can we handle the lack of skin laxity to reach patient satisfaction?

Dr. Frank: Dr.Kotti extensively pointed out that for patients with higher skin laxity, adding volume won’t give you a certain effect. As in surgery, if you need a lift and volume, you still need a lift.

Q4: How do you minimally invasively strengthen the skin?

Dr. Kotti: When patients have a lot of skin looseness, and they don’t have enough fat, and they don’t have to do BBL or body lift, I will avoid them. I injected a lady for three months, every three weeks, and in the end, we got good results without complications. There is no vascularization inside these products, so sooner or later if there is no encapsulation of these amounts of HA, we may encounter complications if we are looking for bigger volumes. So, I would avoid these patients if their expectations were high.

Dr. Schlaudraff: You must manage patients’ expectations and be very open to the advantages and disadvantages of any technique.  They will understand that you cannot fill a very lax skin to make very projected buttocks, but you will need a lift in that situation.

Q5: Is the technique for using MLF1 and MLF2 together in a single session based on injecting them into two separate planes, particularly for treating hip dips?

HYAcorp MFL 2 is administered into the deep fat compartment to optimize volume enhancement, while HYAcorp MFL1 is suitable for injection into the more superficial fat compartment, aiding in shaping and smoothing.

Q6:I've discovered that extracting Genfill filler from the vial is quite challenging. What would be the easiest method to syringe it out?

Genefill Contour and Genefill Contour Plus are to be administered with an 18G/22G cannula. These products should not be transferred from the syringe for any purpose other than injection.

Q7:Could you also clarify what you mean by a maximum of 150 units? Are you referring to 150 x 10, which equals 1500 ml, or just 150 ml per side?

BioScience advises using a total of 15 units of MFL1 and MFL2 per procedure, which equates to a total injected volume of 150 mL of Hyaluronic acid per section.
