Review: سيء جداً ،، يحتاج عدد كبير من الطبقات ليعطي لون جيد وسعره غالي
Review: 気に入ってます！ジェルやってたのですが、手湿疹が出るようになってしまってオフしました。その後爪がかなり薄く、缶詰を開けるにもベコッ！シールを剥がすにもベコッ！何をするにも爪がペラペラで本当に嫌な思いをしていました。 それがこの商品を使い初めて1ヶ月くらいで自爪が厚く硬くなってきました。爪がひっくり返らないのでハイポニキウムも伸びてきてピンクの部分が長くなって嬉しいです！正しい使用方法通りに初日は2度塗り、翌日から1ど塗っていますがたまに忘れます。爪の先剥がれたりしますが、色的にあまりきにならないのと、全体的に爪の色が補正されるし傷がついても目立たないので自爪より綺麗です。

*by C***R on 19 October 2025*

This is a 1-week nail treatment where you coat your nails for 7 days before removing the product. I followed OPI's instructions and nails are visibly firmer and more resistant. Although, a bit flaky on the edges. The nails don't get thicker in any way, they just have denser keratin bonds. I read about people getting damaged nails for overusing, so I am taking breaks before the applications. There were people on reddit using it differently (many ways seem to work), seems worth to try different application routines. Overall it does what it says. But if you have a nail problem because of health issues, this product won't sort that out and your nails will continue to grow week. Always consult a doctor and look for underlying issues.
