Biotin
What is Biotin?
Biotin, also known as vitamin B7 or vitamin H, is a water-soluble nutrient naturally produced by gut bacteria and found in foods like eggs, nuts, and leafy greens. Chemically, it acts as a coenzyme in metabolic processes involving fatty acids, amino acids, and glucose. In cosmetics, it appears in hair care, skin moisturizers, and nail products. It functions by supporting keratin production, the protein building block of hair, skin, and nails, which helps enhance texture and resilience. As a conditioning agent, it forms a protective layer that retains moisture and reduces surface friction, leading to smoother application and feel. Its humectant-like properties draw in hydration, while antiseborrheic effects help manage oil levels without stripping. Typically synthesized for purity in formulations, biotin integrates seamlessly into creams, shampoos, and serums for daily use.
