Candidacy is the one verdict you cannot hand yourself. The home task here is the self-assessment: reading about fractional carbon dioxide treatment and deciding that you fit.
Types of fractional laser
Penn Medicine lists Fraxel lasers, fractional CO2 lasers and fractional erbium lasers as types of fractional lasers. Which one suits you is a clinical decision. The American Society of Plastic Surgeons (ASPS) has a page on laser skin resurfacing for the wider picture.
Realistic gains start with realistic scheduling
Penn Medicine also says non-ablative or fractional laser treatments have shorter recovery times, but you may need multiple sessions. A realistic plan therefore allows for more than one visit. NCBI PubMed Central (NIH) hosts Laser Resurfacing Pearls for readers who want to see the technique discussed in the medical literature.
Sun-damaged skin as a special case
If sun damage is your reason for treatment, the AAD explains how dermatologists treat sun-damaged skin. Read it to prepare questions for your consultation, not to pick a laser.
Reading research without prescribing yourself
Sequential Fractional CO2 and 1540/1570 nm Lasers: A Narrative Review of Preclinical and Clinical Evidence is a review of evidence. It describes a sequential combination of lasers, and it does not tell you which one to ask for.
The conservative rule
If you cannot explain why you are a candidate in terms your clinic has confirmed, treat yourself as undecided. Book the consultation, bring your questions, and let the clinic decide.
