I have tested the serum for a few weeks and am overall satisfied! The bottle looks really luxurious and it's easy to get a good amount of serum out. The consistency is perfect, not too thick and not too watery. It's easy to apply. I have very dry skin and for me, it unfortunately didn't provide enough moisture despite toner and day/night cream. But when I used my regular serum on top of this, it was great, I feel really hydrated and glowy. I can't say if I see any difference in my lines yet, but I will definitely continue using the serum.
