Works really well, help the nail polish to last longer, definitely hardened my nails too. It's really cheap and you can find it everywhere. Will definetely rebuy it anyday.

J'aime cette base pour le vernis. Très bonne qualité.

My nails have gotten shorter due to medical issues and I bought this with high hopes. It's an okay product, but didn't give me the results I expected. It made them shiny, but they didn't grow very much.

Can I just say WOW. I am a nail biter and this product helped me grow my nails at a rate that even I couldn't keep-up with. Plus, it stays on longer than any others I have tried.
