Threonine Description

Threonine is an amino acid that can provide anti-aging and hydration benefits as a skin care ingredient. It is categorized as an essential amino acid because the body cannot make it on its own, so threonine must be obtained from food and/or supplements.

It’s part of a peptide mix (peptides are composed of amino acids) that play a role in contributing to skin’s firm, smooth appearance.

In the body, threonine plays a signaling role with other substances, working in concern to help maintain health. Animal proteins, seeds, and nuts are good dietary sources of this amino acid.

Usage levels of threonine in skin care range from 0.00003%–0.2% in leave-on products, with rinse-off formulas containing up to 0.5%.
