No es ni buena, ni mala, pero es que comparada con todo el mundo de la cosmética coreana, esta es lo que en occidente sería una "Crema Buena" pero si lo hacemos por comparación... hay mejores 

I've only used it once and I didn't like it because it's sticky. But it definitely moisten your face because my skin feel moist in the morning, but other than that, I don't see any other impact.

This is my favourite sleeping pack - I buy it constantly.

My skin always feel totally refreshed and moisturised in the morning, after a night of wearing it.

It also smells lovely too.

Highly recommend!
