Hey all,
I am interested in the ability of HA to potentially regrow fat. I have hollows under my eyes and would like to fill them in. This study seems promising, but I am not sure if I am missing something. If this is really true it seems groundbreaking and disruptive to doctors who make lots of money off HA and fat injectable fillers. Side note, this article is from Taiwan so some of the English is a bit wrong but the idea is there overall.
I know that HA injectables (often performed for volume loss in the face) need to be redone every now and then, but at increasing time intervals. So someone gets them one day, needs another round in 8 months, but then doesn't need another round for 1 year after that and so on. This article seems to say that is partially because the HA allows fat to grow around it, so it takes longer each time for the amount of HA to degrade since HA degrades in everyone but fat only degrades due to age or weight loss.

(hASC = human adipose-derived stem cell)
New adipose tissue formation by human adipose-derived stem cells with hyaluronic acid gel in immunodeficient mice.RESULTS:
hASCs were well attachment and proliferation on the HA gel. In vivo grafts showed well-organized new adipose tissue on the HA gel by histologic examination and Oil-Red O stain. Analysis of neo-adipose tissues by PCR revealed the presence of the Alu gene. This study demonstrated not only the successful culture of hASCs on HA gel, but also their full proliferation and differentiation into adipose tissue.
CONCLUSIONS:The efficacy of injected filler could be permanent since the reduction of the volume of the HA gel after bioabsorption could be replaced by new adipose tissue generated by hASCs. This is a promising approach for developing long lasting soft tissue filler.
Please let me know if my thought process is wrong. I am thinking about buying HA serum to use on my face. Has anyone used this and noticed fat gain/plumping?
