Had my acrylic nails taken off after way too long keeping them on and my nails get so thin and peel away. I work with my hands so the risk of breaking them is extremely high every single day. After applying this varnish they really seem to be very resistant despite bashing them several times a day. No breaking and no peeling 👍🏻 Also arrived early which is nice Update: seems to peel when nail varnish is applied over the top.

Lo compré porque necesitaba fortalecer mis uñas. Llevo 2 semanas y noto mejoría. Lo utilizo comi base de esmalte y encima uso un esmalte con color. Es lo que buscaba.

If you're like me and have struggled with weak, brittle nails, then the Nail Invisible Flex Hardener is a game-changer you need in your beauty arsenal. This product promises to strengthen nails while remaining virtually undetectable, and let me tell you, it delivers on that promise. I've been using this hardener for a few weeks now, and the results speak for themselves. Not only have my nails become noticeably stronger and less prone to breakage, but they also look healthier and more polished overall. What sets this product apart is its invisible formula, which means you can wear it alone for a natural look or as a base coat under your favorite nail polish without any added bulk or texture. Application is a breeze thanks to the smooth, fast-drying formula. With just a few strokes, you can achieve a thin, even layer that provides instant reinforcement to your nails. Plus, the convenient brush applicator makes it easy to reach every corner and edge for thorough coverage.

x3 nails were breaking and put this on and it held them like superglue, but because the broken nails were too far broken I went to my usual nail shop (Nail & Spa) in East Acton... to get added assistance but made sure they added this as a bottom and top coat because i noticed added strength straight away. Thank u for this product; o)
