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。

爪の上に薄い皮膜を作るようなアイテムです。 気泡が入りやすく、薄く塗っても入ることが多いです。 また、自分の爪と相性が悪いのか、お湯に弱いのか、お風呂に入るとすぐにどの指かが一本はペロンと剥がれてきます。 毎日重ねていき、7日後にオフと説明書にありますが、重ねるほど剥がれていきやすくなるため、持ちません。 剥がれる→こまめに塗り直す…という流れになるからか、塗りっぱなしのアイテムよりは爪に意識が向くことが多いです。
