Rolling acne scars are wide shallow depressions with soft edges from fibrous tethering and often need 3-4 fractional CO2 sessions. Each session often brings 3-5 days of redness and peeling and $1,000-$3,000 per-session quotes, while C/E/ferulic serum after laser may ease early swelling.
According to the American Society of Plastic Surgeons, the average surgeon fee alone is $1,829, so totals run higher. According to Journal of Cutaneous and Aesthetic Surgery reviews, sessions are often spaced about six weeks apart. This guide explains what the serum evidence shows and how to plan for rolling scars.

What the serum does after laser
According to SkinCeuticals via PR Newswire, C E Ferulic combines 15% pure vitamin C as L-ascorbic acid, 1% vitamin E and 0.5% ferulic acid SkinCeuticals next-generation announcement. The company describes the mix as neutralizing free radicals and supporting collagen synthesis. In a U.S.
split-face trial reported by Waibel and colleagues in Lasers in Surgery and Medicine, doctors applied that serum with laser-assisted delivery after fractional ablative laser. Delivery of the serum reduced edema by day 7 and reduced erythema on days 3 and 5 versus vehicle, while basic fibroblast growth factor rose at day 5 the split-face laser trial on PubMed. Higher growth-factor signal and less early redness matter for planning time off work. They do not prove faster scar flattening or fewer sessions for rolling scars.
What acne-scar studies found
A randomized investigator-blinded split-face trial reported in the Journal of Cosmetic Dermatology tested the same antioxidant serum after ablative fractional CO2 laser for atrophic acne scars. It focused on repair of erythema, edema and healing rather than final scar scores.
A retrospective chart review summarized by PRIME and Medscape found immediate use of vitamin C/E/ferulic serum after fractional ablative CO2 resurfacing caused no associated complications. The authors limited that safety finding to immediate use and that formula, not longer courses or other products.
Why rolling scars often need more than laser
According to Healio reporting on Dermatologic Surgery, rolling scars come from fibrous bands that tether skin downward. The report described single-session tumescent anesthesia plus extensive subcision, fractional CO2 or erbium laser and 20% TCA peel as safely improving them. Laser alone improves rolling scars less readily than boxcar scars.
According to Dermatologic Surgery data from Sardana and colleagues, meaningful improvement of at least 51% after four nonablative fractional sessions occurred in 43.1% of rolling scars versus 52.9% of boxcar scars. Subcision cuts the tethers so the surface can lift, while laser resurfaces texture and stimulates collagen. Ask a dermatologist whether your pattern is mainly rolling, mixed boxcar and icepick, or mostly tethered.
How to plan sessions, downtime and cost
According to a 60-patient study review in the Journal of Cutaneous and Aesthetic Surgery, typical fractional CO2 courses use 3-4 sessions spaced about six weeks apart, while milder pico or nonablative courses often use 3-6 sessions spaced 3-6 weeks apart the fractional CO2 course review. According to Sozo Clinic guidance updated in 2026, fractional CO2 often causes 3-5 days of redness and peeling, longer at deeper settings, while fully ablative resurfacing often needs one to two weeks. According to the American Society of Plastic Surgeons, average surgeon cost for laser skin resurfacing is $1,829 before anesthesia, facility and aftercare the ASPS laser resurfacing cost page.
Clinics often quote $1,000-$3,000 per session, so multi-session totals run much higher. Bring photos of prior healing and a work calendar to the consult. Ask for a backup plan if redness lasts beyond five days.
- Get a written quote listing surgeon fee, anesthesia, facility fee and aftercare products
- Block 5-7 calendar days after each deep session for peeling, sleep disruption and sun avoidance
- Ask whether subcision, filler or TCA is planned before, with or after laser
- Ask what serum will be applied in clinic, who applies it and what you use at home
