Why Is It Used?

Biotin improves the texture of creams and adds body and shine to hair. Biotin has moisturizing and smoothing properties and can also help improve brittle nails.

Scientific Facts

Widely used in food and vitamin supplements, Biotin plays a role in cell growth. Biotin deficiency may lead to hair loss, skin rash, high cholesterol and heart problems. Nuts, liver, soybeans and fish are rich dietary sources of Biotin.

Safety Information

The Food and Drug Administration reviewed the safety of Biotin and determined that it was Generally Recognized as Safe (GRAS) as a dietary supplement. The safety of Biotin has been assessed by the Cosmetic Ingredient Review (CIR) Expert Panel. The CIR Expert Panel evaluated the scientific data and noted the large number of people exposed to Biotin in food and cosmetic products. The CIREP concluded that Biotin was safe as used in cosmetic products.

CIR Safety Review: The CIR Expert Panel recognized that data on the irritation and sensitization potential of Biotin were absent from the report, but the CIR Expert Panel was of the opinion that if Biotin had a strong potential for irritation or sensitization, case reports would be available in the published literature. The lack of such case reports was an indicator to the CIR Expert Panel that Biotin did not have a strong potential for skin irritation or sensitization. UV absorption data demonstrated that phototoxicity would not be a concern. The CIR Expert Panel noted that a large number of people are exposed to Biotin daily in their diet at dose much higher than those resulting from use of cosmetic and personal care products containing Biotin.
