Reparative Effects of a Topical Antioxidant Serum Containing Vitamin C, Vitamin E, and Ferulic Acid After Ablative Fractional CO
Summary
In a randomized, investigator-blinded, split-face trial (n=64), topical CE Ferulic applied immediately after ablative fractional CO laser significantly improved early wound recovery. Benefits included higher complete scab detachment at day 7, greater reductions in erythema and melanin indices at days 3, 7, and 14, and better hydration with lower TEWL at day 14.
Key Findings
- Day 7 complete scab detachment: 60.9% (CE Ferulic) vs 34.4% (control), p=0.0026
- Greater reductions in erythema index (EI) and melanin index (MI) at days 3, 7, and 14 (all p<0.0001)
- Improved hydration and reduced TEWL at day 14 (p=0.0367 and p=0.0246, respectively)
Clinical Implications
Consider adding CE Ferulic immediately post-procedure to enhance recovery and reduce erythema, dyspigmentation, and TEWL after ablative fractional CO laser, especially in patients at risk for postinflammatory hyperpigmentation.
Why It Matters
This RCT provides controlled evidence that a widely used antioxidant serum accelerates recovery and reduces inflammation and pigmentation after fractional ablative laser, addressing a common post-procedural need.
Limitations
- Short follow-up limited to 14 days post-procedure
- Single-ethnicity cohort (Chinese) may limit generalizability
Future Directions
Multicenter RCTs across diverse skin phototypes with longer follow-up should assess long-term outcomes (e.g., PIH rates, scar remodeling) and comparative effectiveness against other post-laser adjuncts.
