Why Smell Changes With Age
After 40, a man's skin changes. The body starts producing more 2-nonenal — an oil-based compound linked to the stubborn "old man smell" that clings to your shirts, pillow, and car seat.
The Japanese Ritual For Mature Men
Cologne may cover it for a moment. Regular soap may not fully remove it. OTOKO 40 follows a Japanese cleansing tradition with persimmon extract, helping target 2-nonenal at the source.
So you feel clean and confident — and can shake hands, hug, and get close without second-guessing yourself.
