An antioxidant serum helped skin heal faster after fractional CO2 treatment for atrophic acne scars in a 2026 trial of 64 adults. Atrophic acne scars are pitted scars from tissue loss, and the trial supports faster short-term recovery, not proven long-term scar remodeling. The serum was CE Ferulic with vitamins C and E plus ferulic acid, used for 14 days on one cheek with saline on the other cheek. Adults had moderate-to-severe scars and received ablative fractional CO2 laser, which creates tiny wounds to trigger repair.

What did the serum do in the first two weeks?
The treated side showed faster early wound healing than saline. ConsultantLive reports greater complete scab detachment at day 7 on the antioxidant side ConsultantLive healing summary. Redness and pigment measures also favored serum during early recovery.
The Wiley Journal of Cosmetic Dermatology paper reports greater reductions in erythema and melanin index, with better hydration and lower water loss Wiley skin recovery results. For readers, this means less early redness and dryness, not flatter scars yet. Scab shedding, color, and barrier water loss are healing surrogates.
Why does 64 people leave major gaps?
A split-face design allows strong within-person comparison because each person serves as their own control. With 64 adults, it can still detect early healing differences without testing many skin types or clinic methods. The follow-up was days to weeks, so it does not measure lasting scar depth, texture, recurrence, or late safety.
Medical Dialogues and related trial summaries describe this as small-sample, short-term surrogate evidence. Broader laser-combination evidence is also graded low to moderate certainty. That context makes one 14-day comparison useful for aftercare, but weak for claims about permanent repair.
Do these results apply to your skin?
The trial enrolled Chinese patients during a 60-day window in Dec. 2020-Jan. 2021 under registration ChiCTR2300078214, as detailed in the PMC full text PMC trial population details. Findings most directly fit that adult group and single-center protocol.
Age range was 18-50 with moderate-to-severe facial atrophic scars. People outside that range, with mild scars, darker or very sensitive skin, or different laser settings, have less direct evidence. A separate 72-woman trial with 64 completers tested serum for two weeks before and after CO2 along with cleanser, moisturizer, and sunscreen. Background care therefore shapes results, so serum alone is not the full routine.
How should you use this with your clinician?
Treat antioxidant serum as a possible recovery aid, not a scar cure. Ask whether your clinic uses it after ablative fractional CO2, for how many days, and on what skin areas.
Keep strict sun protection and scheduled follow-up because pigment change remains common after CO2 resurfacing. Report slow scab separation, spreading redness, burning, swelling, or dark patches promptly. Ask your clinic how redness, pigment change, and moisture loss will be tracked in the first two weeks.
- Ask what cleanser, moisturizer, and sunscreen to use with any serum
- Ask how to apply the product without picking scabs
- Ask when to return if redness or pigment darkens
