Besides not smoking, don't sip from straws or drink from water bottles or any beverage container with a narrow mouth. Try using a good quality lip primer and extend it beyond your lip line, blending carefully to make the lines less obvious. Use lip balm at night and also extend it beyound your natural lip line to moisturize. Eye creams are richer than face moisturizers, so use a good eye cream around your mouth, one with peptides works best. Hope some of this helps.
