  A general procedure is presented how to improve the effective potential by
using the renormalization group equation (RGE) in MS bar scheme. If one knows
the L-loop effective potential and the RGE coefficient functions up to
(L+1)-loop level, this procedure gives an improved potential which satisfies
the RGE and contains all of the leading, next-to-leading,... , and
L-th-to-leading log terms.
