The pH doesn't need to be 3.5 exactly, but that does sound low. You could patch test it and see how it feels on your skin - near your jawline or ear. To raise the pH you need something neutral or basic - water is neutral, baking soda would be basic. Let the experts chime in though. Does it have a weird smell, others have reported a hot doggy smell, but that could be from nuking the FA? I will be making my first batch this weekend.
My serum hovers around 2.5 also. If you want to adjust the pH so its less acid you can use T.E.A.. Sometimes I substitute a GoW hydrosol for the distilled water which adjusts the pH a bit too.
Which GoW hydrosol flavor do you use? I was gonna try it with orange blossom (neroli) hydrosol. That's the one they use in their Majik C serum. I want the starfruit one but it's never in stock when I check. I hope it turns out well with the neroli one.
nope, didn't work. Sucks bc the texture was great. I did a patch test and it burned, so not sure that is so good. Ahhh. Will stick with basic Vit c with gycerin.
Adding water will only dilute the % of the ingreds really. Since you've already made the serum, you might try just leaving it on for a short period, like 20 min and rinsing it off. That's enuf time to get the LAA into your skin cells but maybe reduce the exfoliating properties and irritation from the low pH if it bothers you, Valerie. HTH a little.
You could always use it on your neck and decollete as well - pending that it doesn't burn in those places. You could always use a little less LAA in the next batch and see if that helps the raise the pH.
I've not used a hydrosol before and so need some clarification, please. Can a hydrosol be used in place of, say, distilled water in this and other formulations? Are the scents of the hydrosols strong enough to give the final product a nice smell?
I realize this thread is from 2010, but I tried Basic vitamin C Serum with glycerine only, and had no stinging.
Made my first batch of Kassys 15% vitamin C And ferulic acid serum, and yowza it burns. Dality age is at 3.5. If possible, how can I save this batch?
