Your intensive repair care for soft or damaged-looking nails:

I also like that the shine has survived showers and endless hand washing. It feels like it might be something which builds over time.Sally J. 🇬🇧Verified BuyerComments by Store Owner on Review by The TeaM on Mon Sep 01 2025The TeaMC’est super que la brillance tienne aussi bien malgré les lavages fréquents ! Avec le temps, l’effet glossy peut encore s’accentuer. Merci pour votre retour positif ! 💅✨Was this review helpful?00
