Meet Dr MitchThe Four Options Side by Side
A quick guide. Your dermatologist will tailor this to your skin.
CO2 Laser
- Best for moderate to deep scarring
- Downtime about 5 to 10 days
- Needs extra care in darker skin
Erbium Laser
- Best for shallow to moderate scars
- Downtime about 4 to 7 days
- Less heat spread than CO2
RF Microneedling
- Best for shallow scars and darker skin
- Downtime about 1 to 3 days
- Needs more sessions
Pico Laser
- Best for mild texture and brown marks
- Little to no downtime
- Not for deep scars
What Lasers Can't Do Alone
Tethered rolling scars need subcision to release the bands pulling them down. Narrow ice pick scars need TCA CROSS or punch excision, because laser energy can't reach their base. This is why lasers usually come after those steps in an acne scar treatment plan.
How We Choose
We weigh up your scar types, skin type, how much downtime you can manage and how many sessions you are comfortable with. Deeper isn't always better: in darker skin, a gentler device used more often can give a better result with less risk.

Common Questions
Comparing Acne Scar Lasers: Common Questions
What is the best laser for acne scars?
There isn't one best laser. CO2 is the strongest, but erbium, RF microneedling and pico each suit different scars and skin types.
Is CO2 or erbium better for acne scars?
CO2 gives more tightening for deeper scars. Erbium usually heals a little faster and suits shallow to moderate scarring.
Is RF microneedling a laser?
No. It uses radiofrequency energy through fine needles, but it is used in a similar way for scars and texture.
Which option has the least downtime?
Pico laser and RF microneedling, though they usually need more sessions.
Can different lasers be combined?
Yes. Plans often combine devices, along with subcision or TCA CROSS.
How do I know which is right for me?
A consultation with side-lighting assessment of your scars and skin type is the best way to decide.
