What Valine does

  • Helps condition skin and hair
  • Supports a softer, smoother feel
  • Helps hold moisture in formulas

Valine is one of the amino acids that make up proteins in the body. The version used in cosmetics is usually L-valine, made by fermentation, a process where microbes produce the ingredient in controlled tanks. Like other amino acids, it is part of the natural protein makeup of skin and hair.

Formulators use valine for its gentle, mild nature. It can help a formula feel lighter and softer, and it helps support moisture on the skin or hair surface. It is often one of several conditioning ingredients in a product.

Frequently asked questions

Is valine the same as the amino acid in my body?

Yes, it is the same amino acid your body uses to build proteins. The version in products is usually made by a controlled fermentation process.

Is valine good for dry hair?

It is used in conditioners to help hair feel softer and more manageable. It works best as part of a full formula with other conditioning ingredients, since one ingredient rarely does the whole job.
