Fraxel Cost for the Upper Lip Lines?

What is the cost of Fraxel laser just on the upper lip area? I have smoked for years and now that I am 35, I quit. I get Jessner peels and Botox. I am pretty much happy with the rest of my skin but my fear is the fine upper vertical lip lines coming through will get deeper with age.I drink my 8 glasses of water a day and drink from the bottle but not sports bottles. Nobody really notices these lines but me, but it is something I want to take care of before they are noticed by others. I use moisturizer with sunscreen also. I would rather do laser than a filler.
