ascorbic acid + riboflavin

Hicee Vitamin C is a line of over-the-counter (OTC) vitamin supplements and quasi-drugs developed and marketed by Alinamin Pharmaceutical (formerly Takeda Consumer Healthcare). The products primarily feature high doses of Vitamin C (ascorbic acid and sodium ascorbate), often combined with Vitamin B2 (riboflavin) to support energy metabolism and skin health. Vitamin C serves as a critical antioxidant and an essential cofactor for enzymes such as prolyl hydroxylase, which is vital for collagen synthesis. The Hicee series is indicated for the supplementation of Vitamin C during physical fatigue, pregnancy, lactation, or recovery from illness, and for the relief of symptoms associated with pigmentation (spots and freckles) and bleeding from the gums or nose.
