high molecular weight is the real king [SEP] 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 boughtso 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 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 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 thisi did give this product a star because it is nicely packaged has the detailed info on the product etc stars down for being marketed as a potent moisturizer
