I have a small cafe au lait on my cheek. I tried a q switch laser about 10 months ago. It got darker at first then faded away and got lighter than it originally was. Since then it has gotten darker again. Is it worth doing a second treatment or will the same thing likely happen again? Could multiple treatments lighten the spot forever or is this something that requires ongoing treatments? Is there a laser that is better for cafe au lait that I should look into? Thanks.
