Should I use less hyaluronic acid in my serum?
I currently make a very simple water-based serum with a few “actives” and with 1% high-molecular-weight hyaluronic acid.
However, I live in a dry climate and don’t really benefit from hyaluronic acid’s humectant qualities (even though I apply it to damp skin and add an occlusive on top).
Why do I use it, then? I like using the hyaluronic acid as a “gelling agent” because unfortunately I get irritation and acne in reaction to a lot of the gel-makers/formers and gums. I haven’t wanted to use something cheaper like glycerin because it is sticky and also apparently a substance that is irritating to my skin.
Anyway, I have three questions:
1) Since hyaluronic acid can only bind to so much water, would using less in my formula mean that it would more-so hold onto the water I apply it over top of, and take less from inside my skin?
2) Does HA take up “available” or “free” water in a formula, that could be used to “hold” the other ingredients? In other words, would using less hyaluronic acid in my formula make more water “available” for the other ingredients (water-soluble powders) to be more thoroughly dissolved/held in?
3) Would it be overall beneficial that I use less than my current 1% concentration of HMW HA in my formula?
Thank you for your time.
