Will CO2 laser treatment worsen melasma?

I have melasma and was treated with Spectra laser, with maintenance approximately every 3 months. I use retin-A 0.5% and hydroquinone 4%. I have had great results from the Spectra laser. I am looking into treatment for lower lid wrinkles. I currently get routine botox treatment but still have static wrinkles and a bunching up appearance when I smile. I’m considering CO2 laser for my under eye area and possibly for my entire face to treat for texture. I am 43 years old, fair skin caucasian.
