Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Riboflavin (vitamin B2) is scientifically validated as an important nutrient for skin health, though its specific use as a targeted supplement for skin conditions is moderately supported. Riboflavin acts as a precursor for the cofactors FAD and FMN, which are essential for various cellular metabolic processes, including those involved in energy production and antioxidant protection. Deficiency in riboflavin can lead to a condition known as ariboflavinosis, with characteristic symptoms such as cheilosis (cracking of the lips and corners of the mouth), seborrheic dermatitis, and a magenta-colored tongue. These manifestations demonstrate the vitamin’s role in maintaining healthy skin and mucous membranes.

Clinical evidence indicates that riboflavin supplementation can resolve skin symptoms caused by deficiency. However, in individuals with adequate dietary intake, additional supplementation has not been proven to provide further skin benefits or improve skin appearance. The use of riboflavin for skin health is therefore primarily justified in the context of preventing or treating deficiency states. No substantial evidence supports its use as a cosmetic agent or for enhancement of skin health beyond correcting deficiency. Thus, while riboflavin is essential for basic skin maintenance, its supplemental use for skin health in the general population is supported only by moderate scientific evidence, and primarily in the context of deficiency correction.
