This stabilized vitamin C formula earns consistent praise for its potency and packaging, but people with skin of color should know the L-ascorbic acid form works better for fairer skin tones. The mix-it-yourself format keeps the vitamin C stable longer than pre-mixed serums, though some find it irritating if their skin barrier is already compromised, and a few have had trouble with the two products blending smoothly. Most who tolerate it rate it highly for brightening and hydration.

Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.

Vitamin E is an antioxidant, and it is often in a formula to keep the other ingredients stable rather than as the active itself. It pairs well with vitamin C, though on its own the evidence for visible change is limited.
