Threonine is an essential amino acid, meaning the body cannot produce it and it must be obtained through diet. In cosmetic formulations, threonine acts as a humectant, helping to attract and bind moisture to the skin. It is also a building block for proteins like collagen and elastin, which are crucial for skin structure and elasticity.

Threonine is an amino acid that functions as a humectant, drawing moisture into the skin to improve hydration. It is also a vital component in the synthesis of proteins like collagen and elastin, which are important for maintaining skin's firmness and elasticity.
Is threonine beneficial for aging skin?
As a precursor to collagen and elastin, threonine can indirectly support skin's structural integrity, which is beneficial for aging skin. Its humectant properties also help to keep skin hydrated, which can reduce the appearance of fine lines.
