CO2 vs HALO fractional?

Fraxel and/or Co2 are best for resurfacing, but erbium is a good alternative. I always combine lasers with microneedling/prp for more robust outcomes. I recommend getting a formal evaluation with a cosmetic dermatologist. Best, Dr. Emer

Hello Swancjack,
Good question. 
Both are very good in the right hands. However, the best results are derived from combination treatments. My preference is Co2. With it I can mix and match as appropriate to the needs of the patient and desired outcome.
I recommend having a consult with a few providers. Those possessing an obvious breath and depth of services with a reasonable history of time performing such procedures are likely capable of providing you a very good outcome.
Many states have lax laws regarding who can operate lasers and perform aesthetic procedures. Therefore, I also recommend you select a provider that has a physician on premises that takes an active hands on roll. If they say they have a Medical Director who is at another location, you may want to consider going else where. 
Lord forbid there is a complication and you're not able to obtain immediate and appropriate care. There's simply no way a laser nurse or technician can provide the same level of care and abilities to address problems as a MD or DO can.
I'm not saying a nurse is less capable than a physician. There are indeed many that are better than some physicians I know. My concern is if a complication arises. Its' simply not worth the risk even if it is a lower cost facility.
Good luck with your procedure. I wish you the very best outcome.
Warmly,

Huge difference, mainly in downtime. HALO is for superficial mild sun damage, downtime is 2-5 days depending on density. CO2 fractional in a high density setting will give you much better collagen stimulation, but redness maybe present for a few weeks to months, depending on the setting. Lasers are merely tools to help the specialist, the best way to achieve a great outcome is to understand your expectations, then tailor a plan (see someone who has HALO, Fractional Lasers, CO2, RF microneedling etc... ) this way they will advice you on the best treatment, not limiting to one or two devices.
