In Type IIB flux compactification realizing the metastable de Sitter (dS) vacuum, the uplift potential can be generated by $\overline{\mathrm{D3}}$-branes at the tip of Klebanov-Strassler throat. Then the uplift potential obeys the scaling law with respect to the tower mass scale $m_{\mathrm{sc}}$, which can be the Kaluza-Klein (KK) mass scale associated with the throat containing $\overline{\mathrm{D3}}$-branes or the bulk tower mass scales, depending on the warping of the throat. On the other hand, in the presence of another throat of stronger warping, the KK mass scale associated with this throat is lower than $m_{\mathrm{sc}}$. Nevertheless, the Higuchi bound and the condition that the tower mass scale is higher than the gravitino mass provide the upper bound on $m_{\mathrm{sc}}$ determined by the lowest tower mass scale (or gravitino mass). This bound also can be interpreted as the lower bound on the lowest tower mass scale determined by $m_{\mathrm{sc}}$. We investigate this bound in detail when the throat containing $\overline{\mathrm{D3}}$-branes is strongly and weakly warped, respectively.
