Biotech or biotechnology, as it applies to cosmetic formulas and ingredients, is the use of biological organisms to produce ingredients.

It uses living organisms (such as yeasts), derivatives of living organisms (extracts or plant components) or biological processes (for example, fermentation) to yield sustainable cosmetic ingredients.

The use of biotechnology to create ingredients is not new – in fact, humans have been utilising biotechnology for thousands of years to create wine from grapes and cheese from milk.
