L'Huile - Barrier Rebuild Oil - 5ml Trial

Yes. All active ingredients are formulated at clinically validated concentrations shown to deliver measurable benefits in skin health and overall wellness. The formulation was developed in collaboration with a certified medical herbalist and our R&D team in France, ensuring each ingredient is included at an evidence-based dosage supported by current scientific research and traditional phytotherapy principles.

Ceramosides™ are plant-derived ceramides extracted from wheat; however, the patented extraction and purification process developed by SEPPIC (France) removes gluten and other residual proteins, including gliadin and glutenin. What remains are only bioactive, skin-supportive lipids — with no detectable gluten, allergens, or proteins.

Each production batch undergoes third-party verification using the RIDASCREEN® Gliadin ELISA assay to confirm that it meets recognized gluten-free regulatory thresholds. Additionally, we can provide a certified allergen-free statement upon request to verify the absence of gluten and other major allergens in the final product.

Yes. The formulation is non-comedogenic and has been dermatologically tested for use on acne-prone and reactive skin types. It is completely biotin-free, as excessive biotin supplementation has been associated in some cases with altered sebum production and exacerbation of breakouts. The ingredient profile is specifically designed to support barrier integrity and maintain a balanced skin microbiome without contributing to congestion or inflammation.

While the formulation contains no ingredients known to be contraindicated during pregnancy or concurrent medication use, we strongly recommend consulting your healthcare provider prior to use if you are pregnant, breastfeeding, or under medical treatment. This ensures the supplement is appropriate for your individual health profile and compatible with any existing therapies or physiological conditions.

Yes. The formulation was developed in collaboration with board-certified healthcare professionals, certified medical herbalists, and our R&D team in France. Each ingredient and dosage has been scientifically evaluated for safety, efficacy, and synergistic activity in accordance with European regulatory and quality standards, which are among the most rigorous in the world. This multi-disciplinary approach ensures the final product is both clinically informed and evidence-based.
