What molecular weight of sodium hyaluronate is best for thickening?
Hi, I tried sodium hyaluronate at 0,50%, molecular weight ~ 1400 kDa. It was quite thick, but not enough. Moreover, there was also a feeling of tightening. Even at 1%, it was not thick enough, and the tightening effect was getting worse. I thought the sodium hyaluronate of this weight would act mainly as a lubricant and cannot have such an effect. Is it because the molecular weight is too low? I have other products that contain only sodium hyaluronate, low and high molecular weight, and even they do not cause such side effects and are very thick. What molecular weight is suitable for thickening?
