Ajinomoto Co.'s humectants grew out of research on the skin’s natural moisturizing factors (NMFs).

Amino acids play a crucial role in the function of the skin NMF (54% of the NMF composition are amino acids). These products protect the skin from dryness, moisturize, promote elasticity and help keep skin healthy and fresh-looking.

PRODEW® 500 is the amino acid blend developed to achieve a new technology for hair care.

Unlike the skin, the presence and the role of naturally occurring free amino acids in hair are not well known, but amino acids applied externally are known to interact with the hair to produce various cosmetic effects such as moisturizing, strengthening structure, color-protection, and the repair of surface damage.

The amino acid component in PRODEW® 500 is modeled after the constituent amino acids of proteins existing in the CMC (Cell Membrane Complex).
