Hello Michelle,
could I use this same recipe, just with lactic acid powder?
Thank you!

In reply to Heather. Hi there, I read this and thought, what if you crush the vit c with a pestle n mortar? would that help maybe ?

In reply to Coco. Interesting! It does say that it worked at pH 7 but not at pH 6 though, which doesn't make me very optimistic that it works at lower pH...

In reply to Ella. I think it could work, although there's a risk of the different components settling unevenly over time.

Hi Michelle, fantastic article! If using the same bottle of distilled water what do you think about pre-mixing the dry vitamin c and bicarb? Could potentially also add aloe vera powder. Then there would be no risk of microbial growth, but easier to make daily/weekly.

Have you ever added sea salt to prevent oxidation of the vitamin C? I ran across this old article and was curious! https://www.nature.com/articles/142293a0

Hi thx I am ordering items now!

The ph strips link is broken tho 🙁

Is there a way to add Vitamin E to this as Ive heard Vit E is good for the skin also? Or to add to skincare routine in another way / diff product? Or no Vit E at all is fine? Thanks

In reply to Aley. I don't know, the extra stuff in the witch hazel could change the pH, react with the L-ascorbic acid or encourage faster microbial growth...

In reply to Hemal. As explained in the post, H+ ions act as a preservative, and should be sufficient in a low nutrient formula that isn't meant to be kept for long.
