@ajaxzDr's will do 12 procedures on you at once if you let them for $$$$$$, they want to do it quick and make the maximum amount. Some like this style as they have no time. The body cannot be rushed, collagen takes between 3-6 months to heal, even if you see nothing on the surface. Now if you need CO2 and it's in a different spot than the cross that's ok. I would not do both at the same time. CO2 does nothing for icepicks until they are raised and become textural, a few sessions of cross and many months. IF they are lasering you now sounds like they don't know scarring well or are treating something else. I want to empower you to take control of your treatment, ... tell them I do not wish to do that this time, I will contact you when I wish to schedule. OR make up a excuse. Allow your body time to heal. TCA CRoss will work on icepicks without a laser, ... do laser latter.Now if that is the only way they will do treatment it's up to you to choose what's best in the situation.
