For rolling acne scars in 2026, expect combined subcision plus fractional CO2, about a week of social downtime, and fees starting near $1,829 per session. Evidence supports vitamin C, vitamin E and ferulic acid serum after ablative fractional CO2 to aid healing and curb redness and pigment. Fractional CO2 is an ablative laser that creates tiny treatment columns and leaves surrounding skin to speed repair. Rolling scars respond best when tethered tissue is released first, then resurfaced.

What the serum adds after laser
In a randomized investigator-blinded split-face trial reported in the Journal of Cosmetic Dermatology, topical vitamin C, vitamin E and ferulic acid improved wound healing, reduced erythema and melanin, and preserved skin barrier versus saline after ablative fractional CO2 for atrophic acne scars, as described in the split-face trial in the Journal of Cosmetic Dermatology. Erythema means visible redness. Melanin change means post-treatment darkening.
A retrospective chart review summarized by Medscape found no reported complications when the same type of serum was applied immediately after ablative fractional CO2 resurfacing. The authors limit that safety finding to immediate use, not longer courses or other formulas. Ask your clinic what exact product, timing, and amount it uses.
How many sessions do rolling scars need?
For rolling scars, moderate cases typically need 2-3 combined subcision plus CO2 sessions spaced 3-4 months apart, according to the Eve Clinics specialist guide, detailed in the Eve Clinics specialist guide. Mild disease may respond to one session. Severe scarring may need 3-4 sessions over 12-18 months.
A retrospective analysis summarized by Medscape found fractional CO2 combined with subcision was more effective than fractional CO2 alone for boxcar-type and rolling-type atrophic scars. It found no significant difference for icepick scars. That result supports combination care when rolling scars dominate.
What does treatment cost in 2026?
The American Society of Plastic Surgeons reports average laser skin-resurfacing cost is $1,829, excluding anesthesia, facility and related fees, as listed on the American Society of Plastic Surgeons cost page. Full-face fractional CO2 for acne scars totals more. More sessions raise the total.
Healthline, citing ASPS data, reports ablative laser averages about $2,330 per session versus about $1,031 for non-ablative. Total cost depends on sessions needed and treatment area. Resurfacing is cosmetic and generally not insurance-covered.
How long is downtime and how do you plan it?
Expect about one week of social downtime after moderate fractional CO2, with lighter settings needing 3-5 days and deeper acne-scar resurfacing needing 7-10 days before makeup covers smoothly, according to the Schrader Plastic Surgery recovery timeline. Redness fades first.
Barrier repair and tone even out later. Plan around that window:.
- Book deeper sessions when you can stay home for 7-10 days.
- Choose lighter settings only when a 3-5 day recovery fits your scar plan.
- Confirm time off, sun avoidance, and makeup rules before booking.
- Ask your clinic which setting you will receive and what cover-up window applies to you.
