Why no improvement 8 months after CO2 treatment?

My family has heavy premature wrinkles. The doctor said maximum CO2 treatment would improve mine. I spent $3,000 that I cannot afford. Swollen, weepy wounds, hours of follow up treatment followed by scabs and redness kept me inside for a month. Eight months later: no improvement at all. F/ups have perfect-skinned women selling expensive products, pushing Botox, etc. I thought this was a medical procedure, not a sales job. Very disappointed, I asked for a refund.
