The largest component of the human body is water, which is said to Stratum PCA and its salts show a high content in the skin as components of NMF. They are also found in plants such as Epidermis corneum account for 60~70% of the body weight. The skin plays an essential role mushrooms*7, onions*8, wheat*9, barley*10, and soybeans*11. if humans are to survive in a dry atmosphere.

As shown in Table 1, NMF is composed of amino acids, sodium pyrrolidone carboxy- 50 60 late (Sodium PCA), and other substances.*2 It is reported that there is a strong correlation between the concentra- 40 tion of amino acid and Sodium PCA and moisture retention of the stratum corneum. It is also known that amino 30 40 3 20 acid levels and PCA levels are significantly higher in healthy skin than in dry skin.* Further, it has been shown Water retained ratio Weight increasing ratio that topical application of a model NMF solution (containing Sodium PCA) to the skin promotes the absorption of 10 20 each component of NMF into the stratum corneum (Fig.2), and thus significantly increases skin moisture and 0 0 flexibility (Fig.3). 01020304050 0102030 Days Days 0.5 (n=6) 55 Fig.4 Hygroscopicity and moisturizing proterty of Sodium PCA (25℃) Fig.5 Moisturizing effect on keratin powder Blank ***:p<0.001 0.45 mean±S.D. 3.5% NMF n=6 ) ■ Amino acids PCA mostly exists in its salt form at pH 5~6 in the skin.

However, Sodium PCA strongly promotes moisture retention*9, suggesting that the body actively synthesizes Sodium PCA with a strong hygroscopic effect.
