Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Vitamin B2, also known as riboflavin, plays an essential role in maintaining healthy skin, but its use in skin care (general) is primarily supported by its biological function rather than robust clinical studies. Riboflavin acts as a coenzyme in numerous metabolic pathways, including those involved in energy production and antioxidant protection, both important for skin health. Deficiency in riboflavin can result in skin disorders such as dermatitis, cheilosis (cracking at the corners of the mouth), and glossitis (inflammation of the tongue). These effects have been documented in clinical and observational studies, and riboflavin supplementation is an effective treatment for deficiency-related skin manifestations.

However, evidence for the use of riboflavin supplementation or topical application in individuals without deficiency to improve general skin health, appearance, or aging is limited. Most support for its inclusion in multivitamin supplements or topical skin care products is based on its role in cellular metabolism and repair rather than direct evidence of efficacy for skin care in the general population. Thus, while there is scientific rationale for riboflavin’s importance in maintaining healthy skin, there is currently a lack of high-quality clinical trials demonstrating benefits beyond correcting deficiency.
