This is really interesting, I would love to try it as well.
Is there a big difference in quality between various brands?
I found one by SenAllis on Amazon that says it is "pure organic hyarulonic acid" and is nearly 3 times cheaper than the brand shown in the OP.
Just want to make sure I don't buy an inferior product or something..
I've only used the one brand. The small bottle lasts a good while so it's cheap enough. If it cost three times as much I'd still buy it because it just works great for me (I may have mentioned how much I like it earlier).
After reading this thread with interest, I went on the makeup forums and researched HA.
Apparently you have to use moisturizer afterwards or it can actually hurt your skin
What is hyaluronic acid? We talked to dermatologists about the benefits of hyaluronic acid and why it's a savior for dry skin. Read our expert advice.www.byrdie.com
Banayan explains the hyaluronic acid needs to be combined with a water-loving lipid to truly hydrate the skin. If not applied in conjunction, the hyaluronic acid could actually be drying out your skin. Hyaluronic acid works by drawing moisture into the skin through its water-attracting (humectant) properties. But without a layer of moisturizer on top to act as a barrier (especially if your skin is already dry or you're in a climate with low humidity), the hyaluronic acid can actually draw moisture from your skin—hence the subsequent tightness.
