  In this paper, we consider the standard semilinear heat equation
\begin{eqnarray*} \partial_t u = \Delta u + |u|^{p-1}u, \quad p >1.
\end{eqnarray*}
  The determination of the (believed to be) generic blowup profile is
well-established in the literature, with the solution blowing up only at one
point. Though the blow-up of the gradient of the solution is a direct
consequence of the single-point blow-up property and the mean value theorem,
there is no determination of the final blowup profile for the gradient in the
literature, up to our knowledge. In this paper, we refine the construction
technique of Bricmont-Kupiainen 1994 and Merle-Zaag 1997, and derive the
following profile for the gradient: %and derive construct a blowup solution to
the above equation with the gradient's asymptotic $$ \nabla u(x,T) \sim -
\frac{\sqrt{2b}}{p-1} \frac{x}{|x| \sqrt{ |\ln|x||}}
\left[\frac{b|x|^2}{2|\ln|x||} \right]^{-\frac{p+1}{2(p-1)}} \text{ as } x \to
0, $$ where $ b =\frac{(p-1)^2}{4p}$, which is as expected the gradient of the
well-known blowup profile of the solution.
