Fractional CO2 Lasers work the best (Active FX and Fraxel re:pair)

First and foremost, you must know what “type” of Fraxel laser would be used for your treatment. There are two types of Fraxel lasers: Fraxel re:pair (a fractional CO2 laser) and Fraxel re:store (an Erbium laser, which is non ablative and is less powerful). Generally, CO2 lasers are considered more effective, so I would highly suggest using a Fraxel re:pair laser OR Active FX instead of a Fraxel re:store laser, if possible. Recovery time with either of those CO2 lasers will be longer than with a Fraxel re:store treatment, but that is because laser treatment with a CO2 laser is more powerful, and as a result, is more effective. Fraxel re:store is NOT a CO2 laser.
It is also very important to also take into consideration how much power the laser generates (meaning the energy that is delivered). A high powered laser works better, since it is more controlled and typically causes less pain and trauma to the tissue. A good power is around 240 quats of energy. Active FX laser has that much power.
