Abstract: We prove some refined asymptotic estimates for positive blow-up solutions to $ \Delta u+\epsilon u=n(n-2)u^{\frac {n+2}{n-2}}$ on $ \Omega $, $ \partial _\nu u=0$ on $ \partial \Omega $, $ \Omega $ being a smooth bounded domain of $ \mathbb{R}^n$, $ n\geq 3$. In particular, we show that concentration can occur only on boundary points with nonpositive mean curvature when $ n=3$ or $ n\geq 7$. As a direct consequence, we prove the validity of the Lin-Ni's conjecture in dimension $ n=3$ and $ n\geq 7$ for mean convex domains and with bounded energy. Recent examples by Wang-Wei-Yan show that the bound on the energy is a necessary condition.
