High Molecular Weight is the Real King!
I had been using High Molecular Weight HA for a couple of weeks on my face/ hair with nice moisturizing results. But at some point I read on beauty blogs and publications that since Low Molecular Weight HA is better absorbed through the skin, that it was a much better option for the face. Made sense to me. Because of this I bought a LMW HA serum to put on my skin. This serum felt differently, watery yet more drying that the HMW HA (HMW can initially feel a bit drying on the skin). My face also felt irritated ( I have acne-prone skin) after the first days of using it. I still decided to buy this powder and the results very similar to the serum I bought.<br /><br />So I decided to do some research on the difference between both, the HMW and the LMW, because I could not understand why the LMW, which is supposed to be a far better option for the skin (according to the beauty industry) , did not give me the good results I have with the HMW. Interestingly enough I found this: &#34;Transepidermal water loss increased by 55.5% with low-molecular weight , and was reduced by 28% with crosslinked resilient , and by 16% with HMW&#34;. So more water loss with LMW? Not good.<br /><br />I also noted this: &#34;There is abundant experimental evidence from the human physiology and biochemistry literature to support the basic notion that LMW-HA is inflammatory, pro-fibrotic, and associated with adult scarring phenotypes rather than fetus-like, scar-free, truly regenerative healing.  The latter is what we want in an any aesthetic procedure, or topical adjunct to a procedure, or just for topical use.&#34; This part here may explain why my face felt irritated and even got a mild breakout after using the LMW HA. More info on this on Barefacedtruth. They have detailed explanation and comments on this.<br /><br />I did give this product a 3-star because it is nicely packaged, has the detailed info on the product, etc. 2 stars down for being marketed as a potent moisturizer.
