Yes, people with atrophic acne scars can ask about vitamin C plus vitamin E plus ferulic acid serum after fractional CO2 laser. According to the Journal of Cosmetic Dermatology, the serum improved wound healing and lowered redness and melanin while preserving barrier function versus saline in the January 2026 trial report. Atrophic acne scars are indented scars left when acne healing produces too little collagen.
The trial result does not make serum aftercare standard for everyone. Scar shape, skin tone, expected gain, risks, and downtime still shape the choice. These questions help a reader use a consultation well.

What did the serum trial actually test?
Adults aged 18 to 50 with moderate-to-severe atrophic acne scars received ablative fractional CO2 laser. PubMed and the Journal of Cosmetic Dermatology describe CE Ferulic serum applied to one cheek and normal saline to the other cheek.
That split-face design allowed direct within-patient comparison. The serum side healed better, with less erythema and melanin, while barrier function stayed intact.
How much can fractional CO2 improve indented scars?
According to a 2025 systematic review of seven studies in Life, most patients gained about 30% to 70% improvement in acne-scar appearance in the June 2025 review. A separate 121-patient retrospective study found effective treatment of atrophic scars without serious adverse reactions.
Response varies by scar shape. Ice-pick scars are narrow and deep, boxcar scars have sharp vertical edges, and rolling scars have broad sloping edges. One fractional-laser study measured 52.9% reduction for boxcar, 43.1% for rolling, and 25.9% for ice-pick scars, so ask which types dominate your cheeks, temples, or jawline.
Will the pigment benefit apply to my skin tone?
The serum trial enrolled Chinese patients over 60 days in December 2020 to January 2021. Healing and pigment response can vary by Fitzpatrick type, sun exposure, and history of dark spots after injury.
Ask whether the redness and melanin findings generalize to your skin. Ask how the clinic adjusts energy, density, passes, and intervals for higher-risk pigment types. Ask what pigment checks happen before full-face treatment.
What risks, downtime, and aftercare should I confirm?
According to the U.S. Food and Drug Administration, laser-surgery risks include incomplete treatment, pain, infection, bleeding, scarring, and skin-color changes in the FDA Medical Lasers page.
Ask about operator training, eye protection, consent, infection control, and scar and pigment history. According to an American Academy of Dermatology meeting report, fractional CO2 resurfacing often causes sunburn-like redness, swelling, and peeling for roughly 1 to 2 weeks, with strict mineral-sunscreen protection emphasized in the post-laser complication tips. Bring old photos, a scar and pigment history, and a two-week work and sun calendar to that visit.
