An upper estimate of the new curvature entropy is provided, via the integral inequality of a concave function. For two origin-symmetric convex bodies in $\mathbb{R}^n$, this bound is sharper than the log-Minkowski inequality of curvature entropy. As its application, a novel proof of the log-Minkowski inequality of curvature entropy in the plane is given.
