It is synthetically manufactured. Because the ethyl-ether modification does not fully mask the reactive vitamin C moiety, it retains more direct antioxidant and tyrosinase-inhibiting activity than some prodrug esters — though it still generally requires some degree of in-skin conversion to reach bioactivity comparable to L-ascorbic acid.
