I have lines in the depressor anguli oris and depressor labii inferioris, I'd like something more long lasting, peel?, laser?

I have lines in the depressor anguli oris and depressor labii inferioris( I looked them up on-line).  These lines run from under bottom lip towards chin (not down to chin as yet) Fillers work ok but last only 2 months. I've tried different doctors but 2 months seems the max on me. I'd like something more long lasting, peel?, laser? lift? not sure. Any suggestions?? (sorry no pic as the lines don't show up well on pic)
