We get some estimates for interior of arbitrary $(q_1,q_2)$-quasimetric ball. We prove theorem of regularization of $(q_1,q_2)$-quasimetric that generalizes corresponding results of R. Alvarado and M. Mitrea. We introduce a notion of $\underline{\lim}$-weak symmetric $(q_1,q_2)$-quasimetric space and prove that every $\underline{\lim}$-weak symmetric $(q_1,q_2)$-quasimetric space satisfies $T_3$-axiom.
Keywords: distance function, open set, interior of $(q_1,q_2)$-quasimetric ball, $\underline{\lim}$-weak symmetry, separation axioms, regularization of a $(q_1,q_2)$-quasimetric.
