MBR Eyelash Booster Serum

Product OverviewEyelash Booster Serum is an eyelash serum developed to help lashes look thicker and longer. Used as directed, it also helps lashes and eyebrows look denser within a precise Beauty Ambassade care ritual. The official formula highlights a Lash Conditioning Lipid Complex, Biotin, and Hyaluronic Acid. Together, these components support the product's role in the routine while helping the treated area look and feel well cared for. Recommended ForRecommended for lashes that look short, sparse or tired, and for brows that have been over-plucked and now read thin. It is a slow, nightly step rather than an instant one. Follow the official frequency and precautions, particularly if skin is reactive. Texture and ExperienceA clear, watery fluid applied with a fine brush along the lash line, much like a liquid eyeliner. It dries down quickly and leaves nothing visible. Key Ingredients Lash Conditioning Lipid Complex: Lipid compounds of the kind naturally present in skin and tissue, used to condition the lash line. Biotin: Vitamin B7, long associated with the condition of hair, skin and nails. Hyaluronic Acid: Hydrates intensely and prevents dryness, smoothes and firms. Conscious FormulaMBR states its formulas are developed and produced in Germany under pharmaceutical-industry manufacturing standards, without animal testing. Formulas can be updated; the current ingredient list is shown in the Ingredients tab above and on the product packaging. Available Size0.1 fl oz / 3 mL Safety InformationFor external use only. Apply along the upper and lower lash line with the brush, never into the eye itself, and rinse with plenty of water if the fluid gets in. Use the brush only on yourself and let the serum dry before going to sleep. Discontinue use if irritation occurs, and keep the container closed and away from direct heat. Not recommended for: Application to the inner waterline or the eye itself Use on irritated, swollen or freshly treated eyelids Wear over lash extensions or false lashes, which stop it reaching the lash line Sharing with another person Frequently Asked QuestionsHow long before I see anything? MBR states the first visible results appear after two to three weeks of nightly use. It is a consistency product, not an overnight one. How do I apply it? On a cleansed, dry, make-up-free lash line in the evening, drawn on with the applicator brush like a fine eyeliner along the upper and lower lashes. Let it absorb. Can I use it on my eyebrows? Yes. MBR states it can be applied to the brows as well, which is useful for gaps left by years of plucking. Do I keep using it every night forever? No. Once you reach the length you want, MBR states three applications a week is enough to maintain it, which also makes the 3 mL last. Can I wear mascara over it? Wear mascara through the day if you like, but apply the serum at night to a clean, bare lash line so nothing blocks it.
