Pure L-ascorbic acid at the concentration that has the evidence behind it, in a low-pH base that keeps it stable and a vessel that keeps light off it. Used every morning it makes tone look more even and gives skin a visible brightness that is difficult to get any other way.

It will oxidise eventually — that is the nature of the molecule. Keep the cap on, keep it out of the sun, and finish it within three months of opening.
