Hello,
I'm going to use Hyaluronic Acid as my base for a Vitamin C serum.
( I want to get the powder form)
When I look for Hyaluronic acid it always seems to be mixed with other trace things...a couple had collagen in them.
Is this OK?...Will it work. I know pure is better, but I can't afford the little i've seen of "Pure" HA
I've done research on this, and I don't want to use Glycerin as my base..
Thanks

You have to be careful of the final serum's pH. Vit. C needs a pH of 3.5 or lower to be effective. HA in water is usually around 6.0. You can buy pH test strips to be sure your final solution is effective.
