Double Serum® (9th Generation)

A well-formulated multi-botanical serum with solid hydration and antioxidant support, but efficacy is limited by weak peptide concentrations, lack of proven anti-aging actives (retinol, niacinamide, AHAs), and reliance on botanical extracts with modest clinical evidence. The biomimetic 2/3 hydric + 1/3 lipidic formula is cosmetically elegant and absorbs well, but the 22 plant extracts are largely present in trace amounts post-preservatives, diluting their individual impact. Turmeric, avocado oil unsaponifiables, and oat extract provide antioxidant benefits, while Palmitoyl Tripeptide-1 and -7 offer cell-signaling support—however, these peptides are typically underdosed in commercial serums and lack the clinical robustness of retinoids or proven peptide concentrations (e.g., Matrixyl 3000 at 3-5%). The formula excels at hydration (glycerin, hyaluronate, pentylene glycol) and antioxidant layering (Vitamin E, turmeric, cocoa), but falls short for visible firming or pore refinement without stronger actives. Fragrance (Parfum) and colorants (CI 14700) add sensory appeal but no clinical benefit. For a luxury serum at this price point, the absence of retinol, niacinamide, or AHA/BHA is a significant missed opportunity. If you're looking for skincare anti aging products or vegan skincare, this is worth evaluating.
