Formulation Deep Dive

The Ordinary’s Multi-Peptide Lash and Brow Serum is formulated as a high-performance, water-based treatment designed to enhance hair density and volume. The carrier system utilizes a high concentration of glycerin and butylene glycol as humectants to ensure efficient delivery of actives into the hair follicle while providing essential hydration to the lash and brow line. The formulation’s efficacy is driven by a concentrated multi-peptide complex, including Myristoyl Pentapeptide-17, Biotinoyl Tripeptide-1, and Acetyl Tetrapeptide-3, which work synergistically with Caffeine and Panthenol (Provitamin B5) to stimulate keratin production and extend the hair growth cycle. Additionally, botanical extracts such as Larix Europaea Wood Extract (European Larch) and Camellia Sinensis Leaf Extract (Green Tea) provide antioxidant support and soothe the follicle environment. The serum is stabilized with a blend of hydroxyethylcellulose and xanthan gum to achieve a lightweight, non-greasy viscosity, preserved by a robust system containing Sodium Benzoate, Phenoxyethanol, and Chlorphenesin.
