DERMATOLOGIST COMPARISON
CO2 Laser vs Secret RF for Acne Scars
THE SHORT VERSION
Fractional CO2 is the stronger resurfacing option for deep boxcar and rolling scars but needs 5–7 days of downtime. Secret RF remodels collagen beneath the surface with 1–3 days of downtime and lower pigment risk. Many plans combine both across sessions.
