Biotin

Definition

Biotin, also known as Vitamin B7 or Vitamin H, is a water-soluble B-complex vitamin that is commonly used in cosmetics and personal care products. It is valued for its conditioning properties and is frequently included in hair care, scalp care, skincare, nail care, and beard care formulations. In cosmetics, biotin is used to help improve the feel and appearance of hair, skin, and nails.

History

Biotin was identified in the early 20th century during research into essential nutrients. Scientists discovered its important role in normal metabolism, and it was later classified as Vitamin B7.

As cosmetic science advanced, biotin became a popular ingredient in shampoos, conditioners, scalp treatments, serums, nail products, and skincare formulations because of its conditioning properties and consumer recognition.

Today, biotin remains one of the most widely recognized vitamin ingredients in beauty and personal care products.
