@hereforitall i understand who you’re refrencing too, his videos made me dig deeper on if it’s actually true because you are right multiple unbiased sources are needed to establish an opinion.

“despite reduction in size and denseness, the small amount of gel presenting into the subcutaneous fat after twelve months of the application evidenced the HA efficacy and long-acting”
These preliminary results demonstrate the ability of the T(2) images for in vivo visualization of the filler agent and also for characterization of tissue modifications. In addition, the diffusion and progressive degradation of the filler agent can be monitored by T(2) measurements over time.

“On high-resolution morphological MR images the HA injection is barely visible, but with quantitative MRI the zone of injection is clearly seen. This is due to HA having a distinctly different transverse relaxation time, T(2) approximately 600 ms, compared with dermal and hypodermal tissues, 35 and 80 ms, respectively.”
I, and histopathologic characterization. While HA fillers are marketed as having a temporary effect of several months, the authors demonstrate that they may persist in the body for up to 9 years. Unlike most previous reports, there was no inflammatory reaction or encapsulation, simply...

A 54-year-old woman received multiple injections of hyaluronic acid filler to the brow region to address volume loss over a 21-month period. She then developed significant pitting edema of both upper eyelids, which persisted for 6 years. Hyaluronidase (Hyalase) was injected into the subcutaneous...

“54 year old woman received multiple injections of hyaluronic acid filler to the brow region to address volume loss over a 21-month period. She then developed significant pitting edema of both upper eyelids, which persisted for 6 years.” “confirms that the hyaluronic acid injected into the brows was responsible for this patient's chronic eyelid edema”
Semipermanent volumizing effects can be achieved by HA injection if the target area has an underlying bony floor. Periosteal stem cells may be activated by HA injection and may contribute to persistent volumizing effects. This treatment may be a much less invasive alternative to fat or bone...

“After long-term follow-up (12-93 months, mean = 21.6), persistent volumizing effects were observed in most patients.”

“Ten of the 14 patients denied any hyaluronic acid facial injections for more than 2 years at the time of the magnetic resonance imaging. All 10 had hyaluronic acid magnetic resonance imaging signal. Five patients denied any hyaluronic acid treatment in specific locations for more than 6 years; all had significant magnetic resonance imaging hyaluronic acid signal in those areas. One patient denied treatment with hyaluronic acid in the orbital region for over 12 years, which showed significant persistent periorbital hyaluronic acid. The most common clinical referral was longstanding “puffiness” in a specific area, questioning the presence of hyaluronic acid, edema, or fat as a cause.“
