Which product ? Fine lines around mouth.

Hello all,

I am very new to this and while I have had success with products I'm having trouble finding one that helps with fine lines around the mouth. My client loves the biolimin c eye serum and the dark spot serum but we can't quiet find success with fine lines. We have tried a sample of the future code breaker samples, and most recently she was given a few samples of the phyto nature serum and she didn't see much difference. Any suggestions on things that have worked well for your clients ? Or something that is a good combo for dark spots and fine lines, I appreciate the help !!
