Riboflavin
What is Riboflavin?
Riboflavin, known as vitamin B2, is a water-soluble vitamin belonging to the flavin group, characterized by its bright yellow pigmentation. Naturally present in foods like dairy and leafy greens, it is produced synthetically or via microbial fermentation for cosmetic use. Primarily functioning as a skin conditioning agent in creams, lotions, and hair products, it helps preserve the skin's natural moisture balance and flexibility. Its humectant properties draw in hydration, while its stable color adds visual appeal to formulations. Riboflavin supports cellular metabolism indirectly through its role in energy transfer coenzymes, contributing to product efficacy without penetration issues due to its large molecular size.
