Soin durcisseur

The texture is so light it disappears into the nail, unlike the thick polishes I've tried before. My soft, peeling nails feel genuinely firmer after just a week of nightly application, and the biotine really seems to do its job.

Three weeks in and my nails no longer bend backwards when I catch them on things, the keratin and biotin mix actually did something. I paint it on before bed and the difference in softness is noticeable by morning.

My cuticles were peeling something fierce before this, but the keratin and biotin formula has genuinely made my nails feel denser within just two weeks. I only apply it every other day and the difference in flexibility is obvious.
