People with atrophic acne scars, depressed scars from tissue loss, can ask if a vitamin C, E, and ferulic serum fits their laser plan. A 2026 trial in atrophic scars reported better healing, less redness and pigment rise, and stronger barrier care than saline after fractional CO2 laser.
Scar shape guides treatment choice. The American Society for Dermatologic Surgery divides these scars into icepick, boxcar, and rolling types in its acne-scars fact sheet. That grouping helps match laser settings and add-on care to the scar.

How do scar type and laser type shape the plan?
Atrophic scars differ in width, depth, and edge shape. Narrow deep pits behave differently from wide box edges or tethered rolling scars. Your clinician uses that pattern to pick energy, depth, and sessions.
Fractional CO2 laser has become a gold-standard option for most atrophic scars. A 2026 Lasers in Medical Science review points to fractional beams that make tiny treatment zones. Nearby untreated skin then speeds repair.
Why combine vitamins C and E with ferulic acid?
L-ascorbic acid and alpha-tocopherol are antioxidants studied for sun-related skin injury. Ferulic acid helps stabilize them in solution. Stability matters because broken-down vitamin serums act less predictably.
Duke researchers found that adding 0.5% ferulic acid to 15% L-ascorbic acid plus 1% alpha-tocopherol doubled photoprotection from about 4-fold to 8-fold by redness and sunburn-cell measures, described in this Duke publication record. The gain came from better vitamin stability plus added protection. That lab finding set up later interest in laser recovery.
What did post-laser trials report?
The 2026 atrophic-scar trial used a split-face design after ablative fractional CO2 laser. One side received the C, E, and ferulic serum, while the other received saline. The serum side showed improved wound healing, lower redness and melanin readings, and preserved barrier function, according to the authors in the Journal of Cosmetic Dermatology report.
A separate split-face trial tested a similar idea after nonablative Fraxel for photoaging. The 2025 study, registered as ChiCTR2300069246, applied CE-ferulic after the procedure. Treated sides showed less redness buildup and steadier hydration than saline sides.
What should you ask before your procedure?
Trial results are narrow. MedEsthetics, reporting on Waibel and colleagues in Lasers in Surgery and Medicine, flags small, short, population-specific studies, including a 15-adult photodamage study and single-center Asian groups, in this post-procedure healing report. Results may not carry across scar subtypes, darker skin, or people prone to post-inflammatory color change.
Routine aftercare can also differ from trial care. SpotCheck Clinic aftercare commonly advises pausing vitamin C, AHAs/BHAs, tretinoin and other cosmeceuticals for about one week after fractional laser. It also notes vitamin E cream often irritates healing skin. Bring your history of dark spots after acne, burns, or procedures, plus a list of current acids, retinoids, and vitamin serums.
