It is shown that two inequalities concerning second and fourth moments of isotropic normalized convex bodies in ${\mathbb R}^n$ are permanent under forming $p$-products. These inequalities are connected with a concentration of mass property as well as with a central limit property. An essential tool are certain monotonicity properties of the ${\mit \Gamma }$-function.
