Hi,
Realistically, 25-50% improvement will be achievable with combination acne scar therapy (these include subcision, scar revision, fractional CO2 lasering, fractional microneedle RF and fractional picosecond lasering) for moderately severe acne.
Generally, after treatment, scars will still be present but will look less obvious, less deep and less craggy.
Complete removal of acne scars is not possible even with repeated treatments and with the “best” treatments.
Hope this helps!
