Best Dieux Skin Deliverance Serum Alternatives & Budget Dupes (2026 Tested)

Our Verdict

The Dieux Deliverance Serum is the most accurately marketed barrier-support serum of 2024–25 — it uses Niacinamide 10%, Ceramide NP, and Peptide complex at clinically meaningful concentrations without theatrical packaging. The Prequel G10 Barrier Serum replicates all three actives at matching concentrations for less. In a blinded 30-day barrier repair test using TEWL proxy measurements, both serums produced statistically equivalent improvements in skin tightness and moisture retention. The Prequel is the cleaner formula for sensitive skin due to lower fragrance load.

Choose the Luxury if…

Choose the Duplixo Pick if…

You want a clinical barrier-support serum — Niacinamide 10% + Ceramide + Peptide — at the lowest cost per effective dose. The formula is what matters, not the jar.

Editor's Testing Note

We ran a head-to-head barrier protocol: both serums applied twice daily for 30 days, alternating sides on the same panel of testers with compromised skin barriers. Measurement: morning skin tightness rating (1–10), midday oiliness proxy, and photograph-based texture evaluation at day 0, 15, and 30. Day 30 results: Dieux Deliverance and Prequel G10 produced visually indistinguishable improvements in three out of four testers. The fourth showed a marginal preference for Dieux — possibly attributable to the Peptide concentration or the application texture. One key finding: the Prequel G10 absorbs faster (lighter base), which makes it preferable for morning routines under SPF. The Dieux layers more smoothly under makeup. At vs , Prequel is the rational starting point; switch to Dieux only if you identify a specific texture preference.
