Longer follow-up must show lasting scar remodeling, scar-grade change, stable pigment, and months-long safety after CE Ferulic post-laser. Atrophic acne scars are depressed scars from collagen loss, and early results show faster healing by day 14 but not durable repair. The test was a randomized, investigator-blinded, split-face trial of CE Ferulic versus saline after ablative fractional CO2 laser, listed as ChiCTR2300078214. PubMed lists the trial record with that design and registration in the PubMed trial record.

What improved by day 14?
On the CE Ferulic side, wounds closed faster than on the saline side. Redness fell more, measured as erythema index, and pigment fell more, measured as melanin index.
Hydration rose higher by day 14 on the treated side. Water loss through skin, called transepidermal water loss, stayed lower. The Journal of Cosmetic Dermatology report in PubMed Central describes these day-14 barrier and color differences in the full Journal report in PubMed Central.
Who was studied?
The trial enrolled adults ages 18 to 50. All had moderate-to-severe facial atrophic scarring scored with the ECCA scale.
Enrollment ran over 60 days in December 2020 to January 2021. ConsultantLive reporting on Zhang and colleagues places the findings in that severity group.
Why might this combination aid recovery?
Vitamin C fights reactive oxygen species from laser injury and curbs tyrosinase, an enzyme that drives pigment. It also supports collagen synthesis, while ferulic acid stabilizes vitamins C and E.
Together that action supports dermal remodeling and less pigment formation after laser, according to Wiley reporting Boo and colleagues in 2026. Henry Ford Health reporting Waibel and colleagues also found less redness and swelling over 7 days and higher basic fibroblast growth factor, a repair-signal protein, at day 5.
What must longer follow-up still prove?
The atrophic-scar trial tracked early healing, redness, pigment, and barrier measures over days to 14 days. It did not measure lasting scar remodeling, scar-grade change, pigment return, or months-long safety, as noted in the Journal of Cosmetic Dermatology review. That gap matters because longer use and sun exposure change pigment risk, especially hyperpigmentation in darker skin.
Medscape abstracting prior chart-review authors notes immediate use caused no linked complications but warns against extending that result to longer courses or other formulas in the Medscape abstract. Bring photos, pigment changes, and sun habits to each follow-up visit. Ask your dermatologist how they will judge scar texture apart from early redness.
- Track scar grade with the same ECCA scale at 3, 6, and 12 months
- Track pigment return, sun protection, and barrier function over time
- Track prolonged-use safety and hyperpigmentation in darker skin
