New Xtrem Flash Gel Top Coat: Up to 21 days of wear & express removal. Exclusively designed for the Green Flash routine, the Xtrem Flash gel top coat nail polish guarantees long-lasting wear for up to 21 days and removes in just 10 minutes, with no filing and no acetone. The polish lifts off in a peel-off process, easily and gently, to protect the natural nail. ⚠️ Compatible only with Green Flash. Not suitable for Green, Active, or other brands’ polishes. Mirror-like shine & plump gel effect: its gel texture forms a protective shield that delivers a rounded, glossy, ultra-shiny finish worthy of a professional gel manicure. Ideal for enhancing color and strengthening the durability of all nail types for everyday wear. Thanks to its high-precision expert brush, application is easy and even. It is instantly dry and durable after curing under a 24W or 36W LED lamp or UV light for gel nails. How to use? After applying and curing 1 coat of Green Flash Vitaminized Base Coat and 2 thin layers of Green Flash color, apply a thin layer of Top Coat on 4 flat fingers (excluding the thumb - to prevent the gel texture from slipping into the cuticles and causing the manicure to lift prematurely). Cure under LED Lamp (Top Coat program). Repeat for the thumb separately, keeping it flat, then cure. The Xtrem Flash Top Coat does not require a primer, nor wiping after curing!
