“[This serum] combines 15% L-ascorbic acid, vitamin E, and ferulic acid to protect against free radicals, reduce oxidative damage by up to 41%, and improve fine lines, firmness, and skin tone ...
Ascorbic acid efflux by embryos of dicot plants is a well-established mechanism of iron reduction and a step obligatory for iron uptake. [a] All plants synthesize ascorbic acid. Ascorbic acid functions as a cofactor for enzymes involved in photosynthesis, synthesis of plant hormones, as an antioxidant and regenerator of other antioxidants. [96]
Vitamin C megadosage is a term describing the consumption or injection of vitamin C (ascorbic acid) in doses well beyond the current United States Recommended Dietary Allowance of 90 milligrams per day, and often well beyond the tolerable upper intake level of 2,000 milligrams per day. [1]
Ascorbyl glucoside (AA-2G) is an ascorbic acid derivative that contains at least one glycosyl group. Ascorbyl glucoside is commonly used in cosmetic products to administer vitamin C topically. Ascorbyl glucoside exhibits superior stability and penetration ability compared to ascorbyl phosphate salts, but the rate of its in vivo conversion to ...
Scurvy is a deficiency disease (state of malnutrition) resulting from a lack of vitamin C (ascorbic acid). [1] Early symptoms of deficiency include weakness, fatigue, and sore arms and legs.

Ascorbic acid is easily oxidized and so is used as a reductant in photographic developer solutions (among others) and as a preservative. [citation needed] In fluorescence microscopy and related fluorescence-based techniques, ascorbic acid can be used as an antioxidant to increase fluorescent signal and chemically retard dye photobleaching.
