By combining high-resolution observations from JWST and HST, we have measured the stellar masses, star formation rates (SFRs), and multi- wavelength morphologies of galaxies in the CANDELS fields. Furthermore, based on rest-frame 1um morphologies, we have derived spatially resolved stellar mass and SFR surface density (Sigma_ and Sigma_SFR) profiles for 46313 galaxies with reliable structural measurements at 02.5), the median radial profile of Sigma_SFR_ is nearly parallel to but slightly steeper than that of Sigma__. This results in mildly negative gradients in the specific SFR (sSFR) profiles across all stellar mass bins considered. These findings indicate that galaxies at z>2.5 cannot grow in size via only in-situ star formation, challenging the understanding of galaxy size evolution beyond the cosmic noon. In contrast, at z<2.0, the sSFR profiles transition to exhibit more and more positive gradients at lower redshifts, consistent with an inside-out growth scenario where star formation preferentially expands the galactic outskirts.
