With regards to your question:
Fractional CO2 lasers also generate more heat than Erbium lasers and as such have better collagen synthesis etc but this also confers a higher risk of heat-related side effects namely Post-Inflammation Hyperpigmentation (PIH) , redness and longer downtime.
As the other doctors have mentioned, this is where Fractional RF machines have a safer side effect profile with a lower risk of PIH.
That being said, one would also have to consider the type of acne scars you have as different scars are treated differently and not all scars respond well to machine-led treatments.
In conclusion, all these devices have their pros and cons, and can deliver good results when executed to its full potential.
Hope that helps.
All the best!
The current options for ablative treatment of acne scars would be mostly limited to :
I would say that for easy understanding, fractional CO2 has the best results because it is able to penetrate deeper into the skin. However, it’s a double edged sword and has much higher chances of side effects like PIH ( Post-Inflammatory Hyperpigmentation) and Hypopigmentation.
Fractional Erbium and Fractional RF were developed precisely because of the higher chances of those side effects, and thus they do not penetrate as deep or ablate as strongly. However, they still give a good result with much lower chances of side effects.
Thus, your idea that fractional RF goes deeper than fractional CO2 is likely not true, based on the above principles.
To help you decide, mainly you need to think through the following factors :
