For severe acne scars, treatment results tend to be poorer.
You may consider the following strategies:
- Opt for more aggressive Fractional CO2 laser treatment parameters.
- Consider combination treatments such as subcision, scar excision.
Fractional CO2 Laser Treatment is effective for treating most kinds of atrophic acne scar and has a downtime of 5 - 10 days.
Subcision is when a small needle is used to release the fibrous scar tissue beneath the scar. As the area heals, the new collagen also helps to push the base of the acne scar up.
Scar excision involves using a tiny hole-punch like device to cut out the acne scar. The wound is then sutured closed, with the stitch removed within a week
For severe acne scars, sometimes only 20-30% overall improvement may be achieved.
