I agree.I personally don't like multiple hyphens in a word group
The case of hyaluronic acid is influenced by common use in the supplement/cosmetic areas but the "no-hyphen" version definitely dominates even in articles from Google scholar (in contrast to LMW heparin which only shows up in academic articles and the hyphen version is quite common). In both cases, the subsequent use of the term in such articles avoids the issue by using LMW or HMW, very common hyphen-free abbreviations in academia A few show up as "low-molecular weight"
The wiki article shares with the literature a range of options
The degradation products of hyaluronan, the oligosaccharides and very low-molecular-weight hyaluronan, exhibit pro-angiogenic properties. In addition, recent studies showed hyaluronan fragments, not the native high-molecular weight molecule, can induce inflammatory responses in macrophages and dendritic cells in tissue injury and in skin transplant

In any case, an informed reader already knows that molecular modifies weight and that low modifies "molecular weight" and that it is not "low-molecular" weight
I'm surprised you ask... Hyaluronic acid is sold in cosmetics as an "anti-aging compound", and "women of a certain age" feel the urge to lather it on. It (allegedly) keeps your skin looking young.How does this affect my life?
... and apart from the bit about tumors, that has to be good news... for those who sell it.Hyaluronic acid (HA; conjugate base hyaluronate), also called hyaluronan, is an anionic, nonsulfated glycosaminoglycan distributed widely throughout connective, epithelial, and neural tissues. It is unique among glycosaminoglycans in that it is nonsulfated, forms in the plasma membrane instead of the Golgi apparatus, and can be very large, with its molecular weight often reaching the millions. One of the chief components of the extracellular matrix, hyaluronan contributes significantly to cell proliferation and migration, and may also be involved in the progression of some malignant tumors
(We need a "tongue-in-cheek" emoticon. Allegations are common in the nutraceutical and cosmetics areas. No well-conducted study - see #2 here - has shown health benefits of antioxidants either - it's a theoretical proposal and ahuge industry)I'm surprised you ask...
