Product Insights
This 15 ml illuminating booster serum from Les Cosmetiques blends niacinamide, panthenol, sodium hyaluronate, and peptide complexes (Palmitoyl Tripeptide-1 and Tetrapeptide-7) to enhance skin radiance, barrier strength, and hydration. Its formulation also includes multiple humectants such as glycerin, pentylene glycol, and sorbitol, plus a stable vitamin C derivative (ascorbyl glucoside) for antioxidant protection and brightening. Potential drawbacks are the inclusion of fragrance (parfum) and phenoxyethanol, which may cause irritation for very sensitive or allergy-prone skin.
Comparative Analysis
Positioned as a high-performance radiance booster, it sets itself apart by combining niacinamide with peptide-driven Tripeptide-1/Tetrapeptide-7 and hyaluronic acid for layered brightening, while the presence of fragrance and phenoxyethanol may limit its appeal to ultra-sensitive users.
