Verdict: Skinceuticals C E Ferulic scores higher overall, delivering 15% L‑ascorbic acid with proven antioxidant synergy (Journal of Cosmetic Dermatology) and superior stability (Consumer Labs). La Roche‑Posay Retinol B3 offers a gentler retinol option that’s better tolerated by sensitive skin (La Roche‑Posay clinical data) but lacks the broad anti‑aging power of C E Ferulic. For users prioritizing maximal antioxidant protection, C E Ferulic is the clear winner; for those needing a low‑dose retinol with added niacinamide, Retinol B3 is preferable.
