Embryolisse Lashes & Brows Booster 6.5ml is a fortifying lash and brow serum from the long-running French pharmacy skincare brand. A dual-purpose treatment designed to lengthen, thicken and condition lashes — and densify brows — over time, with a 96% naturally-derived formula built around centella asiatica, castor oil, arginine and biotinoyl tripeptide-1. About Embryolisse Embryolisse is the long-running French pharmacy skincare brand best known for its iconic Lait-Crème Concentré — a multi-purpose moisturiser used backstage by makeup artists for decades. The brand's wider range extends that pro-grade, accessibly-priced ethos into targeted treatments — with the Lashes & Brows Booster as its lash- and brow-specific serum. Key ingredients Biotinoyl Tripeptide-1 — the key active in modern lash-fortifying serums, in a low concentration designed to be safe alongside daily mascara use. Castor Oil — long-time conditioning oil for lash and brow hair. Centella Asiatica Extract — soothing and anti-fall support. Arginine and Panthenol — for hair strength and condition. 96% ingredients of natural origin per the brand. Who it's for Anyone wanting fuller, denser, more conditioned lashes and brows — particularly suited to those whose lashes are weakened by mascara, false-lash use, or extension wear. Dermatologically and ophthalmologically tested per the brand, including for sensitive eyes and contact-lens wearers. How to use Always start with clean, dry lashes and brows — remove all eye makeup. In the morning, apply a thin layer along the upper lash line and through the brows as a makeup base. In the evening, re-apply a thin layer as a fortifying overnight care. Allow to fully absorb before applying any other product. Continue use for at least 28 days for visible results per the brand.
