NAIL HARDENER & BASE COAT is a must-have base for stronger nails—and a long-lasting manicure. It is a dual-action formula that combines the best of botanicals and science to create the ultimate base coat for weak, brittle nails. Designed to condition, shield, and provide a durable surface for optimal polish wear, this base coat goes beyond just being a primer: it cares for nails below the surface, too.

What makes it special: It creates a durable surface to bond polish for extended wear while shielding nails from damage, primes nail surface for smooth, effortless application and a natural look, and encourages healthier, stronger-looking nails with a blend of botanical oils and extracts—which helps prevent breaking, chipping, cracking, peeling, and staining.

Good to know: Formulated without Formaldehyde, Toulene, DBP, Camphor, Ethyl Tosylamide, Acetone, Formaldehyde Resin. Vegan, gluten-free, cruelty-free.

Key ingredients: Strengthening Biotin (Vitamin B complex), Antioxidant Vitamin A, Moisturizing Vitamin B5, Conditioning Saccharomyces/Iron Ferment and Safflower Oil, Nourishing Florium Complex (Londontown's antioxidant-enriched, flower oil emulsion of Rapeseed Flower Oil, Cucumber Extract, Garlic Extract, Evening Primrose Oil, Chamomile Extract, and Vitamin E).

How to use: Start with clean nails. Apply one thin, even coat to bare nails. Follow with 1-2 coats of lakur and any kur top coat as a final touch.
